NATS ATC Eligibility Requirements

We may earn a commission from some links on this page. Recommendations remain editorially independent.

Can you apply to become a NATS air traffic controller?

NATS sets minimum eligibility requirements for its Trainee Air Traffic Controller programme because candidates are applying to train for a safety-critical occupation.

According to the current NATS recruitment information, applicants must:

• be at least 18 years old when they apply;
• have the right to work in the United Kingdom without requiring sponsorship now or in the future;
• possess five GCSEs at Grade 4 or above, or Scottish National 5 qualifications at Grades A-C;
• include English and Mathematics among those qualifications;
• provide accepted equivalent qualifications where applicable;
• be capable of passing Security Check clearance, commonly called SC clearance;
• complete the required initial Class 3 medical assessment;
• comply with the NATS drug and alcohol policy from the point specified by NATS;
• provide complete and truthful information throughout recruitment, medical screening and security vetting.

Meeting these conditions allows you to be considered. It does not guarantee that your application will be accepted or that you will pass the NATS assessment process.

The requirements may change between recruitment campaigns. Check the official NATS trainee careers page before applying rather than relying solely on an old recruitment PDF, forum discussion or preparation website.

NATS eligibility requirements at a glance

This table summarises the currently published route. The vacancy notice and candidate instructions for your own campaign take priority if they differ.

Minimum age requirement

You must be aged 18 or over when you submit your application.

Being nearly 18 is not the same as meeting the requirement. If the application form asks you to confirm that you are already 18, answer according to your age on the date you apply.

Is there a maximum age limit?

The current NATS trainee eligibility section does not publish a general maximum application age.

That does not mean every older candidate will automatically satisfy the medical, training or employment requirements. It means that age alone should not be treated as a disqualifying upper limit unless NATS states one in the applicable campaign.

Candidates should distinguish between:

• the minimum recruitment age;
• individual medical fitness;
• the time required to complete training;
• pension or retirement considerations;
• unsupported claims about an alleged maximum age.

An old article or candidate comment should not be used to invent an age limit that NATS does not currently publish.

Academic qualification requirements

NATS currently requires five GCSEs at Grade 4 or above, including English and Mathematics.

For candidates using Scottish qualifications, the published requirement is five Scottish National 5 qualifications at Grades A-C, including English and Mathematics.

Equivalent qualifications may be accepted.

What does Grade 4 mean?

In the current numerical GCSE grading system in England, Grade 4 is generally treated as a standard pass.

Applicants with older letter-graded GCSEs, qualifications obtained elsewhere in the United Kingdom or overseas qualifications may need to show how their results compare with the NATS standard.

Do not assume that an unfamiliar qualification will be rejected, but do not assume equivalence without evidence either.

English and Mathematics are compulsory

You need acceptable qualifications in both English and Mathematics.

Having five other GCSEs does not satisfy the published requirement when English or Mathematics is missing.

The English requirement reflects the importance of:

• understanding written instructions;
• processing spoken information;
• communicating precisely;
• learning technical material;
• operating safely in an English-language training environment.

The Mathematics requirement does not mean that applicants need advanced university mathematics. It establishes a minimum educational foundation before cognitive ability is assessed during recruitment.

Are equivalent qualifications accepted?

NATS states that equivalent qualifications are accepted.

Possible cases may include:

• older GCSE grading systems;
• Scottish qualifications;
• qualifications obtained in Wales or Northern Ireland;
• international school qualifications;
• vocational qualifications with recognised equivalence;
• alternative English or Mathematics credentials.

Acceptance depends on how NATS evaluates the evidence. A preparation website cannot certify equivalence on the employer’s behalf.

Before applying, prepare:

• your qualification titles;
• awarding organisations;
• subjects;
• grades;
• dates obtained;
• certificates or official statements of results;
• an equivalency statement where one is reasonably required.

Contact NATS recruitment when the application material does not explain whether your qualification is acceptable.

What if you cannot find your certificates?

NATS states that qualifications may be checked during the vetting process.

If your original certificates are missing, contact the awarding organisation or your former school or college early. Replacing documents may take time.

Do not enter an estimated grade or claim a qualification you cannot support.

A difference between the application form and later verification may delay the process or raise concerns about accuracy.

Do you need a university degree?

A degree is not listed as a minimum requirement for the current NATS trainee route.

Applicants may therefore come from different educational backgrounds, including:

• school or college;
• apprenticeships;
• university;
• military service;
• technical work;
• customer service;
• administration;
• operations;
• other unrelated occupations.

A degree does not exempt a candidate from any part of the selection process. Degree holders must still meet the minimum school-qualification requirements or provide accepted equivalents where requested.

They must also pass the same applicable assessments, medical checks and security vetting.

Do you need previous air traffic control experience?

Previous air traffic control experience is not listed as a minimum requirement for the trainee programme.

The purpose of the route is to recruit candidates who have the potential to complete professional controller training.

You are not expected to arrive with:

• an air traffic controller licence;
• professional separation knowledge;
• operational radar experience;
• airport-control experience;
• pilot qualifications;
• an aviation degree.

However, later recruitment stages may examine whether you understand the career and have researched NATS.

You should be able to explain:

• what NATS does;
• the difference between aerodrome, approach and area control;
• why the occupation is safety-critical;
• why controller training is demanding;
• why mobility may be necessary;
• why you personally want the role.

The NATS air traffic controller career guide explains these responsibilities without pretending to replace professional training.

Right to work in the United Kingdom

NATS currently requires applicants to have the right to work in the UK without needing sponsorship now or in the future.

This is more restrictive than simply being able to enter the United Kingdom or work temporarily under limited conditions.

NATS does not offer sponsorship for this route

The published requirement means that candidates should not apply on the assumption that NATS will sponsor a work visa for the trainee position.

You need immigration status that permits you to meet the stated condition.

Your exact position depends on your status and documents. Official GOV.UK guidance should be used for questions about:

• British or Irish citizenship;
• settled or pre-settled status;
• indefinite leave to remain;
• time-limited immigration permission;
• student restrictions;
• dependant status;
• work visas;
• share codes;
• pending immigration applications.

An independent ATC preparation website cannot determine whether your status satisfies NATS recruitment requirements.

Right to work is not the same as citizenship

A person may have the legal right to work in the UK without being a British citizen.

Conversely, having permission to visit, study or remain in the UK does not always create an unrestricted right to perform the job described.

NATS separately requires security vetting. Passing a right-to-work check does not guarantee SC clearance.

How right to work may be proved

Depending on your status, evidence may involve:

• an eligible passport;
• immigration documents;
• a Home Office online share code;
• confirmation through the Employer Checking Service;
• other documents accepted under current Home Office rules.

Use the official GOV.UK right-to-work service to understand the available methods.

Do not upload identity or immigration documents to an unofficial preparation website.

Security clearance requirement

NATS currently requires trainee applicants to pass SC-level security clearance.

Security Check vetting is separate from the aptitude assessments. A strong test score cannot replace the security requirement.

The process may examine information connected with:

• identity;
• address history;
• employment;
• education;
• criminal records where relevant;
• finances where relevant;
• overseas residence or travel;
• personal associations where relevant;
• other matters required by the vetting authority.

The exact scope is determined by the official security process, not by candidate speculation.

Does overseas residence prevent clearance?

Do not assume that time spent abroad causes an automatic rejection.

However, overseas residence can make verification more complex because authorities may need sufficient information to assess the candidate’s background.

Applicants should follow the instructions provided for the relevant clearance level and explain their history accurately.

Do not invent a universal residency rule for NATS unless it is expressly stated in the current vacancy or vetting instructions.

Honesty is essential

NATS warns candidates that false statements or deliberate omissions may disqualify them.

A past issue is not necessarily assessed in the same way as an attempt to conceal it. The correct approach is to:

• answer the question asked;
• provide accurate dates;
• declare relevant information;
• explain discrepancies;
• supply documents when requested;
• contact the authorised vetting team when unsure.

Do not omit information because you believe it is unimportant or embarrassing.

Use the official NATS careers information and your candidate instructions for a more detailed explanation of security-clearance preparation and documentation.

Class 3 medical requirement

To work operationally as an air traffic controller, you must hold the applicable CAA Class 3 Medical Certificate.

NATS currently requires applicants to undergo an initial Class 3 medical assessment in full.

The UK Civil Aviation Authority states that the initial examination must be conducted by an authorised aeromedical examiner at an aeromedical centre.

The examination considers the applicant’s medical history and current findings. It is not limited to one eyesight or hearing check.

Areas assessed may include:

• vision;
• colour perception;
• hearing;
• cardiovascular health;
• respiratory health;
• neurological history;
• mental health;
• medication;
• substance use;
• other relevant illnesses, injuries or treatments.

The complete standards are determined by the CAA.

A medical condition does not always equal automatic rejection

Candidates sometimes search for simple answers such as:

• “Can I become a controller with ADHD?”
• “Will anxiety disqualify me?”
• “Can I apply if I have migraines?”
• “What eyesight is allowed?”
• “Does asthma prevent Class 3 certification?”

These questions cannot be answered responsibly from the diagnosis name alone.

The CAA explains that medical certification considers the complete medical history and examination findings. The only definitive way to know whether a certificate can be issued is to complete the appropriate medical process.

Possible outcomes may depend on:

• the nature of the condition;
• severity;
• symptoms;
• stability;
• treatment;
• medication;
• side effects;
• supporting reports;
• operational implications;
• the applicable medical standard.

Do not stop prescribed medication or alter treatment to improve an application without guidance from the clinician responsible for your care.

Full medical disclosure

NATS asks applicants to disclose their complete history honestly.

Its current eligibility information specifically reminds candidates to declare relevant matters including:

• illnesses and injuries;
• mental health conditions;
• addictions;
• neurodevelopmental conditions;
• migraines;
• asthma;
• visual problems.

These examples are disclosure categories, not a published list of automatic exclusions.

Failure to declare relevant medical history or medication may jeopardise medical certification and, in serious cases, have wider licensing consequences.

The NATS medical requirements guide explains what to research before the formal assessment.

Drug and alcohol requirements

Air traffic control is a safety-critical occupation. NATS therefore applies strict drug and alcohol rules.

Current NATS information states that applicants must comply with its drug and alcohol policy from the point of signing their contract.

NATS also indicates that random drug and alcohol testing may occur from the first day of employment.

Candidates should understand that:

• illegal drug use is incompatible with the safety-critical role;
• so-called legal highs may also be prohibited;
• alcohol limits for safety-critical work are stricter than ordinary social expectations;
• medication can affect fitness for duty;
• new medication may need to be reported through the required channels;
• misuse or non-disclosure may affect employment and licensing.

Do not rely on informal estimates of how long a substance remains detectable. The correct standard is compliance with the policy and fitness for safety-critical duty.

Mobility and place of work

NATS describes air traffic controllers as a mobile grade.

Candidates may need to train or work at a location selected according to organisational requirements.

Current NATS information tells applicants to consider the effect of relocation before applying. It also states that candidates cannot express a preference during the eligibility-registration stage described on its careers page.

Possible locations include:

• one of the initial training organisations;
• an airport where NATS provides air traffic control;
• Swanwick Control Centre;
• Prestwick Control Centre.

Your eventual posting may depend on:

• the specialism for which you train;
• your performance and demonstrated skills;
• course availability;
• staffing needs;
• operational requirements.

Mobility is a practical eligibility issue

A candidate may satisfy the age and qualification requirements but still find the route unsuitable when relocation is impossible.

Before applying, consider:

• whether you can move during training;
• housing costs;
• relationships and family commitments;
• a partner’s employment;
• caring responsibilities;
• commuting limitations;
• whether you can accept a posting without choosing the location.

Do not assume you can complete training remotely or wait indefinitely for a preferred airport.

See the NATS training process and career guides, together with the official NATS careers page, for currently listed training and operational sites.

Workplace conduct and behaviour

NATS includes workplace conduct in its eligibility self-check.

The organisation expects employees to:

• respect differences;
• value colleagues’ opinions;
• listen to others;
• consider how their behaviour affects people;
• remain calm and measured during setbacks;
• manage pressure appropriately.

These expectations matter because controller work depends on cooperation, clear communication and trust.

A candidate who performs well on cognitive assessments may still be unsuitable when they cannot:

• accept feedback;
• communicate respectfully;
• take responsibility;
• work within procedures;
• cooperate with colleagues;
• manage frustration professionally.

Behavioural suitability may be explored through the NATS Situational Judgement Test, interview and observed assessment activities.

English-language expectations

The current academic requirement includes an accepted English qualification.

In addition, the recruitment and training process is conducted in English. Candidates must be able to:

• understand written instructions;
• process spoken information;
• communicate clearly;
• learn technical terminology;
• answer interview questions;
• participate in training;
• use precise operational language after receiving instruction.

The Stage 2 process currently includes an online listening-comprehension assessment, which is separate from merely holding an English qualification.

Meeting the GCSE requirement does not guarantee success on a listening test. The NATS Stage 2 tests guide explains how to practise information retention ethically.

Does NATS require a driving licence?

A driving licence is not listed among the general minimum eligibility requirements on the main current trainee page.

However, transport may become a practical consideration because:

• some shifts begin or end outside normal public-transport hours;
• a training site may be difficult to reach;
• an operational posting may require relocation;
• local commuting arrangements vary.

Check the specific vacancy and location information rather than treating a driving licence as either universally required or universally unnecessary.

Does NATS require UK citizenship?

The main current NATS eligibility section states a right-to-work requirement rather than a general British-citizenship requirement.

Applicants must have the right to work in the UK without sponsorship now or in the future and must also pass the required security clearance.

Nationality, immigration status and security eligibility are related but separate issues. Do not infer that:

• every non-British citizen is ineligible;
• right to work guarantees security clearance;
• a temporary visa necessarily satisfies the no-sponsorship condition;
• citizenship removes the need for vetting.

Candidates with questions about their immigration status should use official Home Office guidance. Security-clearance questions should be addressed through the authorised recruitment or vetting route.

How NATS checks eligibility

The process may involve several forms of verification.

Application declarations

You may be asked to confirm that you satisfy the core requirements before progressing.

An incorrect declaration can result in rejection later, even if the online application initially continues.

Qualification checks

NATS may verify:

• subjects;
• grades;
• awarding organisations;
• certificates;
• equivalent qualifications.

Keep your information consistent across the application and any later forms.

Right-to-work checks

NATS must verify that a prospective employee has the legal right to work under the conditions required for the role.

Security vetting

The official vetting process reviews the information necessary for SC clearance.

Medical assessment

An authorised aeromedical process determines whether you meet the Class 3 medical standard.

Ongoing obligations

Eligibility is not always a one-time event.

Controllers may need to maintain:

• valid medical certification;
• required security status;
• professional conduct;
• drug and alcohol compliance;
• competence;
• fitness for operational duty.

Common eligibility mistakes

Applying before turning 18

The published requirement applies at the time of application, not at a later training date.

Counting five GCSEs without English or Mathematics

The total number alone is insufficient. English and Mathematics must be included.

Assuming a degree replaces missing qualifications

NATS does not state that a university degree automatically overrides the published GCSE requirement. Obtain confirmation if your academic route is unusual.

Guessing qualification equivalence

Equivalent qualifications are accepted, but the employer determines whether the evidence satisfies its requirement.

Confusing a temporary right to work with the NATS condition

The official criterion requires the right to work without sponsorship now or in the future. Check your individual status against that wording.

Hiding medical history

NATS and the CAA emphasise honest disclosure. Concealment can be more serious than the underlying condition.

Assuming a condition automatically disqualifies you

Medical certification is based on formal standards and individual assessment. A diagnosis name alone may not provide a definitive answer.

Treating security clearance as a criminal-record check only

SC clearance can involve wider identity, history and security verification.

Expecting to select a preferred airport

NATS states that posting is determined by skills, training and business needs.

Preparing for aptitude tests before checking eligibility

Commercial test preparation has little value when a candidate clearly fails a non-negotiable requirement. Complete the eligibility check first.

What eligibility does not guarantee

Meeting the minimum requirements does not guarantee:

• an invitation to every assessment stage;
• a passing aptitude-test result;
• success in the situational judgement or listening tests;
• success at the assessment centre;
• medical certification;
• security clearance;
• a conditional offer;
• a preferred training date;
• a preferred location;
• completion of training;
• eventual controller validation.

Eligibility is the entry threshold. Selection and training assess whether the candidate can develop and demonstrate the competencies required for the occupation.

What to verify officially

Before applying, verify the following directly with NATS and the relevant official authorities:

• whether applications are open;
• the minimum age;
• whether any campaign-specific age conditions apply;
• the number and grades of required qualifications;
• accepted English and Mathematics qualifications;
• treatment of international or equivalent qualifications;
• documents needed as evidence;
• the exact right-to-work condition;
• whether sponsorship is available;
• the required security-clearance level;
• any residency or documentation expectations associated with vetting;
• the current Class 3 medical process;
• the applicable drug and alcohol policy;
• when the policy begins to apply;
• mobility and posting requirements;
• training locations;
• whether workplace adjustments are available;
• any campaign-specific conditions in the vacancy notice.

Use the official NATS trainee air traffic controller page as the primary recruitment source.

Use the UK Civil Aviation Authority’s ATCO medical guidance for Class 3 medical information.

Use GOV.UK right-to-work guidance for immigration-document and employment-status questions.

Bottom line

The current NATS trainee eligibility standard requires applicants to be at least 18, hold the required English, Mathematics and other school qualifications, possess the right to work in the UK without sponsorship, and be capable of passing Class 3 medical and SC security-clearance processes.

Candidates must also accept the practical conditions of a safety-critical career: complete honesty, strict drug and alcohol rules, professional behaviour, extended training and possible relocation without a preferred posting.

Check these requirements before spending money on preparation. When your eligibility is uncertain, obtain an answer from NATS, the CAA, the Home Office or another competent official authority rather than relying on an unofficial forum response.
