NATS Air Traffic Controller Recruitment Guide

Becoming an air traffic controller with NATS

NATS recruits and trains air traffic controllers for some of the United Kingdom’s busiest and most complex airspace environments.

Becoming a NATS controller is not simply a matter of completing one aptitude test. Candidates may need to progress through eligibility screening, multiple online assessments, a virtual assessment centre, an interview, an air traffic control knowledge test and a practical exercise before receiving a conditional offer.

Successful applicants then begin an extended training process leading towards a Student Air Traffic Control Licence. After completing initial training, they continue learning at an operational unit until they validate and qualify as licensed air traffic controllers.

The exact recruitment sequence can change between campaigns. According to the current NATS recruitment information, the process is divided into four assessment stages, but candidates should always verify the published stages when their own application window opens.

This independent guide explains:

• what NATS air traffic controllers do;
• who can apply;
• how the current recruitment stages are structured;
• which abilities may be evaluated;
• what happens during training;
• where controllers may be posted;
• how preparation can help;
• which details must be checked directly with NATS.

What is NATS?

NATS is the United Kingdom’s leading provider of air traffic control services. Its controllers support the safe and efficient movement of aircraft through UK airspace and at airports where NATS provides the air traffic control operation.

NATS reports handling approximately 2.5 million flights each year. Its activities include managing aircraft travelling through controlled airspace, coordinating arrivals and departures, and helping pilots maintain safe separation while traffic conditions continually change.

The trainee air traffic controller route is designed for candidates who have not yet qualified as operational controllers. Successful applicants are employed and trained through a structured programme rather than being expected to arrive with an existing controller licence.

The current route is described by NATS as a Level 5 Apprenticeship Trainee Air Traffic Controller course. Initial training is followed by operational training at the unit to which the trainee is assigned.

What do NATS air traffic controllers do?

Air traffic controllers help aircraft move safely and efficiently through different phases of flight.

Their work requires much more than watching aircraft symbols on a screen. Controllers must absorb information, identify conflicts, communicate clearly, anticipate how situations may develop and make safe decisions under strict procedural constraints.

NATS identifies three broad controller specialisms.

Aerodrome controllers

Aerodrome controllers, often associated with airport control towers, manage aircraft and authorised vehicles operating on or close to an aerodrome.

Their responsibilities may include:

• managing aircraft departures and arrivals;
• issuing taxi instructions;
• coordinating runway use;
• monitoring aircraft and vehicle movements;
• maintaining safe spacing in the airport environment;
• responding to changes in weather, traffic and runway availability.

The exact division of responsibilities depends on the airport and the controller’s validated positions.

Approach controllers

Approach controllers manage aircraft approaching or departing an airport within the relevant area of responsibility.

They may need to:

• organise arriving traffic into an efficient sequence;
• maintain safe separation;
• coordinate aircraft climbing away from an airport;
• respond to route, altitude or weather changes;
• communicate with pilots and neighbouring control sectors;
• transfer aircraft at the appropriate point.

This work requires strong spatial understanding because the controller must build and continuously update a mental picture of aircraft moving in three dimensions.

Area controllers

Area controllers manage aircraft travelling through larger sectors of controlled airspace, often while the aircraft are in the en-route phase of flight.

They may work with:

• multiple aircraft following different routes;
• changing speeds and altitude profiles;
• sector boundaries;
• crossing traffic;
• weather deviations;
• coordination requests from other controllers;
• traffic entering and leaving their area of responsibility.

NATS states that Aerodrome, Approach and Area controllers perform different roles and may be based at different locations. Candidates are not normally recruited into a position where they can assume they will receive one particular specialism or workplace.

Is the NATS career suitable for you?

Air traffic control is a safety-critical occupation. The work may be rewarding, but the selection and training demands should not be underestimated.

A potentially suitable candidate is someone who can:

• remain accurate when several pieces of information compete for attention;
• follow rules without becoming inflexible when circumstances change;
• communicate calmly and precisely;
• accept correction and learn from mistakes;
• maintain concentration over repeated tasks;
• make timely decisions using incomplete but sufficient information;
• work effectively with colleagues;
• take responsibility for their actions;
• manage pressure without allowing urgency to become panic;
• relocate when operational requirements demand it.

Aviation enthusiasm can provide motivation, but interest alone does not demonstrate suitability. NATS must assess whether an applicant can develop the cognitive, behavioural and practical competencies required for safe controller training.

You can explore the role in more detail in the NATS air traffic controller career guide.

NATS eligibility requirements

Candidates should check the official criteria before investing substantial time in an application or preparation course.

The current NATS eligibility information states that applicants must:

• be at least 18 when applying;
• have the right to work in the United Kingdom without requiring sponsorship now or in the future;
• possess five GCSEs at Grade 4, or Scottish National 5 qualifications at Grades A-C, including English and Mathematics;
• hold accepted equivalent qualifications where applicable;
• be able to obtain the required security clearance;
• complete the required Class 3 medical assessment;
• comply with the NATS drug and alcohol policy from the point specified by NATS.

These are minimum conditions, not a guarantee of selection.

Do you need a degree?

A university degree is not listed among the current minimum eligibility requirements.

Candidates with degrees may apply, but a degree does not replace the need to demonstrate the abilities assessed during selection. Likewise, applicants without a degree may be eligible if they satisfy the published qualification requirements.

Do you need aviation experience?

Previous aviation or air traffic control experience is not listed as a current minimum requirement for the trainee route.

This means the recruitment process is intended to identify potential rather than merely reward prior industry knowledge. However, applicants should still understand the role, the organisation and the realities of training before attending an interview.

Medical requirements

Operational controllers must meet the applicable medical standards and hold a valid CAA Class 3 Medical Certificate.

Medical suitability is assessed individually. Candidates should not assume that a particular diagnosis, medication or medical history will automatically produce either acceptance or rejection.

NATS emphasises the importance of making complete and honest declarations during the medical process. Candidates should consult the UK Civil Aviation Authority’s current medical standards and contact an appropriate aeromedical professional when they need guidance about their circumstances.

Read the dedicated NATS medical requirements guide for an explanation of the process and its limits.

Security clearance

Candidates must also satisfy the required security vetting standard.

Security decisions are made by the relevant authorities and cannot be guaranteed by a preparation website, recruiter or candidate account. Applicants should provide complete, accurate and consistent information throughout the process.

See the NATS eligibility requirements guide for the points candidates should prepare to document for security clearance.

Is NATS currently accepting applications?

The official NATS trainee controller page currently displays the application window as closed and states that there is no confirmed timetable for reopening applications.

Candidates can check their eligibility and register their interest for future recruitment updates. A third-party website should never invent or predict a reopening date.

Recruitment availability can change. Always confirm the current position on the official NATS careers website rather than relying on an old article, forum discussion or archived PDF.

The current NATS assessment process

The current official recruitment information describes four assessment stages.

This structure reflects the process currently published by NATS. It should not be treated as a permanent guarantee for every future campaign.

For a stage-by-stage explanation, use the NATS assessment process guide.

Stage 1: online ability tests

Candidates whose registrations are approved may be invited to complete eleven online ability tests.

NATS states that these assessments are designed to examine abilities such as:

• spatial awareness;
• logical thinking;
• numerical ability;
• sense of direction;
• reaction speed.

These are broad ability categories. They do not provide enough information to justify claims that a particular independent exercise is an exact copy of a NATS test.

The number, sequence, interface and scoring rules should be taken from the instructions supplied to the candidate for that recruitment campaign.

What might the ability tests demand?

Although individual tasks can differ, candidates may need to:

• interpret visual information quickly;
• distinguish relevant from irrelevant details;
• track changes accurately;
• make directional judgements;
• apply a rule consistently;
• perform simple calculations without avoidable errors;
• respond within a limited period;
• balance speed with accuracy.

The challenge is not necessarily advanced academic difficulty. A task can become demanding because information is presented quickly, attention must be sustained or several simple operations must be coordinated.

Virtual proctoring

NATS currently states that the Stage 1 and Stage 2 assessments are virtually proctored by Aon. Candidates are required to consent to webcam and microphone use for identity validation. NATS indicates that a candidate who does not provide the required consent will be unable to take the assessments.

Candidates should prepare their equipment and environment before the assessment rather than waiting until the test is about to begin.

Useful checks include:

• confirming that the computer meets the stated technical requirements;
• testing the webcam and microphone;
• using a reliable internet connection;
• choosing a quiet and private room;
• removing prohibited materials;
• reading identification requirements;
• disabling unnecessary notifications;
• following the instructions concerning breaks and permitted equipment.

The dedicated NATS Stage 1 tests guide explains how to prepare without attempting to reproduce protected assessment material.

Stage 2: situational judgement and listening comprehension

Candidates who pass Stage 1 may be invited to two further online assessments:

1. a Situational Judgement Test;
2. a Listening Comprehension test.

Situational Judgement Test

A situational judgement assessment presents workplace situations and asks the candidate to evaluate possible responses.

The purpose is not to discover a clever way to manipulate the test. Candidates should demonstrate professional judgement consistent with a safety-critical working environment.

Relevant principles may include:

• prioritising safety;
• following procedures;
• communicating concerns;
• taking responsibility;
• remaining calm;
• escalating an issue appropriately;
• cooperating with colleagues;
• avoiding assumptions;
• responding proportionately;
• learning from feedback.

An answer that appears decisive is not automatically effective. Acting without enough information, ignoring procedures or refusing to consult others can create unnecessary risk.

Read the NATS Stage 2 tests guide for original practice scenarios and response-analysis methods.

Listening Comprehension test

Listening comprehension can be particularly demanding because candidates must process information that may not remain visible.

The assessment may require the candidate to:

• concentrate on spoken information;
• retain key facts;
• distinguish similar details;
• follow a sequence;
• identify the meaning of a message;
• answer accurately without replaying information, where replay is unavailable.

Preparation should focus on active listening rather than memorising reported questions.

A useful method is to practise identifying:

• who is involved;
• what happened;
• when it happened;
• where it happened;
• which numbers or conditions matter;
• what action is required.

The NATS Stage 2 tests guide provides original, non-official listening exercises.

Stage 3: virtual assessment centre

Candidates who pass Stage 2 and satisfy the relevant minimum requirements may be invited to a virtual assessment centre conducted through Microsoft Teams.

According to the current NATS description, Stage 3 includes:

• an interview;
• an Air Traffic Control knowledge test;
• retesting of previous assessments while the candidate is observed.

The NATS interview

The interview may explore whether the candidate understands the role and can provide credible evidence of the behaviours required in a demanding training environment.

Preparation topics can include:

• motivation for becoming an air traffic controller;
• understanding of NATS;
• awareness of the training commitment;
• communication;
• teamwork;
• resilience;
• accountability;
• responding to mistakes;
• working under pressure;
• willingness to relocate;
• professional conduct.

Candidate reports published on community websites can suggest themes worth considering, but they should not be treated as a verified list of exact questions.

Prepare personal examples rather than memorised scripts. The STAR structure can help:

• Situation: briefly establish the context;
• Task: explain your responsibility;
• Action: describe what you personally did;
• Result: explain the outcome and what you learnt.

Use the NATS interview guide to build structured but authentic responses.

The ATC knowledge test

The knowledge test should not be confused with the cognitive ability assessments.

Ability tests examine how a candidate processes information. A knowledge test examines what the candidate has learnt and understood.

Candidates may benefit from developing a high-level understanding of:

• what NATS does;
• the principal types of air traffic controller;
• why separation and coordination matter;
• the differences between tower, approach and area control;
• the training pathway;
• the responsibilities associated with a safety-critical role;
• current public information supplied by NATS.

Do not copy flashcards or reproduce questions allegedly remembered from a real assessment. Candidate-created Quizlet or Brainscape sets are not authoritative specifications of the current test.

The NATS Stage 3 assessment centre guide explains how to study public information ethically for the knowledge test.

Observed retesting

NATS currently states that candidates may retake previous assessments while being observed during Stage 3.

Candidates should therefore develop stable competence rather than rely on a single unusually strong performance. Practising only enough to recognise one exercise format may not transfer effectively when the task is observed or presented differently.

Stage 4: practical exercise

Candidates who pass Stage 3 may be invited to complete a practical exercise.

The official page states that this stage may be held:

• virtually through Microsoft Teams; or
• face to face at the NATS Whiteley office.

A practical assessment may require candidates to understand instructions, process changing information and make decisions in a structured task.

It should not be assumed that the exercise requires professional controller knowledge. NATS is assessing trainee candidates, not already licensed controllers.

Useful transferable skills include:

• building an accurate mental model;
• following a rule system;
• communicating clearly;
• updating decisions when conditions change;
• prioritising competing demands;
• recovering constructively after an error;
• avoiding impulsive responses;
• maintaining accuracy under observation.

Independent preparation cannot reproduce the exact exercise without official permission and complete current information.

The NATS practical exercise guide focuses on general task-management methods rather than claimed inside knowledge.

What happens after the assessments?

A candidate who passes the assessment stages may receive a conditional offer of employment.

The offer remains subject to the relevant conditions, including medical and security clearance. Passing the practical exercise does not remove these requirements.

NATS currently explains that candidates who achieve the required Class 3 medical clearance can be assigned to a training course and given an employment start date. The security clearance process begins within the timetable determined for the candidate’s intended start.

Delays can occur because:

• training places are limited;
• medical assessments require additional information;
• security vetting takes time;
• operational workforce requirements change;
• course dates or locations are adjusted.

Candidates should avoid making irreversible employment, housing or travel decisions until they have received and understood their formal instructions.

NATS air traffic controller training

Selection is only the beginning.

The current NATS route includes initial training leading towards a Student Air Traffic Control Licence, followed by operational unit training leading towards full validation.

Initial training

NATS describes the trainee route as involving approximately one to two years of training at an initial training organisation.

Its current recruitment page also explains that most college-based training is completed within approximately one year to eighteen months, although the duration depends on factors such as specialism and individual progress.

Initial training combines theory and practical sessions.

Trainees may need to demonstrate competence in areas such as:

• aviation and air traffic control principles;
• procedures and rules;
• communication;
• simulator-based control tasks;
• traffic planning;
• safe decision-making;
• maintaining an operational picture;
• responding to developing situations.

This is professional training. Independent aptitude-test preparation is not a substitute for the instruction delivered by an approved training organisation.

Student licence and unit training

After gaining the required Student Air Traffic Control Licence, the trainee is posted to an operational unit.

Training continues under supervision until the trainee validates on the required positions and becomes eligible for the full controller licence.

The time required can differ considerably. Progress depends on:

• the specialism;
• unit complexity;
• training opportunities;
• individual performance;
• local validation requirements;
• operational circumstances.

Read the NATS training process guide for a detailed explanation of each phase.

Training and working locations

NATS emphasises that air traffic controllers are employed in a mobile grade.

Candidates may be required to train or work in a location selected according to organisational needs. The official eligibility information warns applicants to consider the personal effect of relocation before applying.

NATS currently identifies two initial training locations:

• NATS Corporate and Technical Centre in Whiteley, Hampshire;
• Global ATS at Gloucestershire Airport near Cheltenham.

After obtaining the Student Air Traffic Control Licence, a trainee may be posted to an airport or control centre where NATS operates.

Locations listed by NATS currently include:

• Aberdeen Airport;
• Belfast City Airport;
• Belfast International Airport;
• Bristol Airport;
• Cardiff Airport;
• Farnborough Airport;
• Gatwick Airport;
• Gibraltar International Airport;
• Glasgow Airport;
• Heathrow Airport;
• London City Airport;
• Luton Airport;
• Manchester Airport;
• Southampton Airport;
• Stansted Airport;
• Prestwick Control Centre;
• Swanwick Control Centre.

NATS states that posting decisions depend on the trainee’s skills, training and business requirements. Candidates cannot safely assume that they will receive their preferred region or airport.

See the NATS air traffic controller career and training process guides before deciding whether the mobility requirement is realistic for you.

NATS salary and benefits

Trainees are paid during training.

The official NATS page currently displays salary figures identified as 2025 rates:

These figures should not be treated as guaranteed current rates for a future intake. Salary scales, allowances and employment terms can change.

NATS also currently refers to benefits including:

• a contributory pension scheme;
• 28 days of annual leave plus public holidays;
• voluntary benefits;
• employee networks and social clubs;
• peer support;
• family-friendly and wellbeing policies.

Before making a financial decision, verify the offer applicable to your recruitment campaign on the official NATS careers page. Published figures may separate basic pay, allowances, shift-related elements and qualified-controller earnings.

How difficult is NATS selection?

NATS selection is competitive and demanding, but difficulty cannot be reduced to one published pass rate.

A candidate must progress through different types of assessment. Strength in one area does not guarantee strength in another.

For example:

• strong numerical reasoning does not automatically produce effective listening;
• fast reactions do not compensate for careless decisions;
• aviation knowledge does not replace spatial ability;
• test practice does not replace honest interview evidence;
• passing online tests does not guarantee success in a practical exercise;
• passing all selection exercises does not guarantee medical or security clearance.

The most useful approach is to treat the recruitment process as a series of distinct requirements rather than searching for a single trick that supposedly unlocks the whole process.

How to prepare for NATS assessments

Preparation should develop transferable skills and familiarity with timed assessment conditions.

It should not focus on obtaining recalled questions or reproducing a confidential assessment.

Step 1: understand the current process

Start with the official NATS recruitment page.

Record:

• the eligibility requirements;
• the current assessment stages;
• the delivery method;
• technical requirements;
• deadlines;
• required documents;
• medical and security conditions.

Do not begin with an old forum post or historical recruitment diagram.

Step 2: establish a baseline

Complete short, original exercises across several skill categories.

Measure:

• accuracy;
• completion rate;
• response time;
• types of error;
• concentration over time;
• performance after a mistake.

A baseline helps prevent random practice. It identifies whether your main issue is comprehension, speed, accuracy, attention or strategy.

Step 3: isolate weak skills

Practise one skill at a time before combining several demands.

Examples include:

• mental arithmetic;
• interpreting direction;
• tracking moving information;
• listening for precise details;
• applying logical rules;
• evaluating workplace responses;
• responding accurately under time pressure.

Step 4: introduce timed practice

Timing should be added gradually.

First learn an accurate method. Then reduce the time available while preserving decision quality.

Repeatedly rushing through unfamiliar exercises can reinforce poor habits.

Step 5: practise in a realistic environment

Because the current online stages are virtually proctored, candidates should become comfortable working:

• at a desk;
• without interruptions;
• using the intended device;
• with the webcam and microphone active;
• without checking a phone;
• without unapproved notes;
• for sustained periods.

Step 6: prepare for later stages

Do not stop preparing after the online ability tests.

Allocate time to:

• researching NATS;
• understanding the controller role;
• preparing honest competency examples;
• reviewing public ATC information;
• practising active listening;
• explaining your motivation;
• thinking through relocation and training commitments.

The How to prepare for NATS ATC selection guide provides a structured study plan, including practice-resource comparison and diagnostic-led scheduling.

A sample six-week preparation framework

The ideal schedule depends on your starting level and the notice provided by NATS. The following framework is an example, not an official NATS timetable.

Week 1: orientation and baseline

• Verify the current official recruitment process.
• Review every eligibility requirement.
• Complete short baseline exercises.
• Identify technical and environmental requirements.
• Record your strongest and weakest skill areas.

Week 2: accuracy foundations

• Practise numerical accuracy.
• Work on directional reasoning.
• Review basic logic methods.
• Analyse errors rather than merely recording scores.
• Begin short active-listening exercises.

Week 3: attention and spatial processing

• Practise tracking visual information.
• Work on spatial relationships.
• Introduce controlled reaction-time exercises.
• Continue listening practice.
• Increase session length gradually.

Week 4: time pressure and judgement

• Add realistic time constraints.
• Practise original situational judgement scenarios.
• Review safety-critical decision principles.
• Alternate cognitive tasks to reduce dependence on one format.
• Recheck technical readiness.

Week 5: later-stage preparation

• Research NATS and the controller role.
• Prepare personal STAR examples.
• Review public information relevant to ATC knowledge.
• Practise explaining your motivation clearly.
• Consider relocation and training implications honestly.

Week 6: consolidation

• Complete mixed timed sessions.
• Review recurring errors.
• Reduce excessive last-minute practice.
• Prepare identification and equipment.
• Protect sleep and maintain a stable routine.
• Read the candidate instructions again.

This plan should be adapted to the actual invitation and deadlines supplied by NATS.

Ethical practice material

Appropriate preparation includes:

• original aptitude exercises;
• generic reasoning practice;
• active-listening exercises;
• personal interview preparation;
• public research about NATS;
• practice using timed conditions;
• reflection on professional judgement.

Inappropriate preparation includes:

• seeking leaked questions;
• sharing remembered test content;
• copying protected assessment interfaces;
• using another person to complete an assessment;
• using prohibited notes or tools;
• misrepresenting qualifications or experience;
• attempting to bypass virtual proctoring.

The objective is to improve the abilities required for training, not to create a false assessment result.

Common preparation mistakes

Treating every online source as current

Older articles may describe previous NATS recruitment systems. Stage names, providers and delivery methods can change.

Use the current official careers page as the primary reference.

Assuming NATS uses FEAST

FEAST is associated with EUROCONTROL and participating organisations. It should not automatically be equated with the current NATS process.

NATS presently publishes its own four-stage assessment description. Candidates should not assume that FEAST, DART or MULTI-PASS is involved unless NATS explicitly confirms this for the relevant campaign.

Read What is FEAST? for the correct European context.

Confusing NATS assessments with the FAA ATSA

The Air Traffic Skills Assessment is associated with the United States Federal Aviation Administration hiring system.

It is not the name of the NATS recruitment assessment.

See What is the ATSA? for the US process.

Practising only the easiest skill

Candidates often repeat exercises they already enjoy because improving scores feels encouraging.

Effective preparation devotes more time to recurring weaknesses.

Sacrificing accuracy for speed

Fast incorrect responses rarely demonstrate the ability being assessed.

Develop a reliable method first, then increase speed.

Memorising interview scripts

A rehearsed answer can sound polished but collapse when the interviewer asks a follow-up question.

Prepare genuine examples and understand what each example demonstrates.

Ignoring mobility

NATS explicitly warns candidates that posting depends on business needs and that they may be required to work elsewhere in the United Kingdom.

Consider the practical implications before applying, not after receiving an offer.

Underestimating training

Passing selection does not make a candidate a qualified controller.

Initial and operational training remain demanding, and continued employment or progression depends on meeting the required standards.

Limits of preparation

Preparation can help you:

• understand instructions more quickly;
• become familiar with timed assessment conditions;
• identify weak skill areas;
• improve accuracy;
• develop active-listening habits;
• structure interview examples;
• research the role;
• reduce avoidable technical problems.

Preparation cannot:

• guarantee a pass;
• reveal the exact current questions;
• replace the required aptitude;
• guarantee medical certification;
• guarantee security clearance;
• guarantee a particular posting;
• guarantee completion of training;
• convert an unofficial simulator into the real assessment.

Be cautious with any provider claiming to offer exact NATS questions, a guaranteed passing score or an authorised replica unless NATS itself confirms that claim.

You can also review the available NATS aptitude test preparation package from ATC Practice.

Affiliate disclosure: We may receive a commission if you purchase through this link, at no additional cost to you. Third-party preparation materials cannot guarantee the exact tests, questions, timings or assessment format assigned by NATS.

What to verify officially

Before applying or sitting an assessment, verify the following directly with NATS:

• whether the application window is open;
• the current eligibility requirements;
• the qualifications accepted as GCSE equivalents;
• the right-to-work requirement;
• the current assessment stages;
• the number and type of online assessments;
• the assessment provider;
• virtual-proctoring requirements;
• webcam, microphone and device requirements;
• assessment deadlines;
• the delivery method for Stage 3 and Stage 4;
• retake or reapplication rules;
• medical certification requirements;
• the required security-clearance level;
• training start dates;
• training locations;
• salary and allowance rates;
• operational posting arrangements;
• required documents.

The principal reference should be the official NATS trainee air traffic controller careers page.

Historical NATS documents from 2013 or 2016 may help illustrate how controller recruitment was presented in the past, but they must not be used as definitive descriptions of the present process.

Bottom line

The NATS trainee air traffic controller route combines eligibility screening, cognitive assessment, behavioural and listening tests, an assessment centre, a knowledge test, an interview, a practical exercise and an extended training programme.

The best preparation is broad and ethical. Develop the underlying abilities, understand the role, prepare genuine interview evidence and become comfortable performing under controlled assessment conditions.

Most importantly, use the current NATS careers information for the definitive process. Recruitment windows, assessment arrangements, salary rates and training details can change.
