Pre-hire aviation aptitude tests for airlines and MROs: what they show and what buyers should ask for

An aviation aptitude test is a standardized pre-hire assessment that measures abilities, and sometimes personality or knowledge, that bear on how a candidate will perform in training and on the job. For airlines and maintenance, repair and overhaul (MRO) organizations it supports a hiring decision. It does not make the decision.

This guide is for training managers, HR leads and training providers who buy, build or deliver pre-hire screening for pilots, technicians, cabin crew or ground staff. It is not a preparation guide. When this post was researched in October 2026, search results for the term were mostly candidate practice-test pages, so it covers the employer side: what the rules say, what evidence to demand and how a training provider can offer screening honestly.

The adverse impact example uses invented numbers. Regulatory facts are dated as of October 2026, and rules differ by country, so check your competent authority and your employment counsel. This is general information, not legal advice.

Key takeaways

• An aviation aptitude test supports a selection decision next to a structured interview and a qualification check, and it is not a medical or clinical assessment.
• EU rules require operators to have flight crew psychologically assessed before line flying, yet UK CAA guidance says using a psychometric tool is not mandatory, and the sources reviewed show no equivalent rule for technicians or ground staff.
• A 2019 FAA review found few pilot selection processes built on a recent job analysis, and only one of nine with available information disclosed fairness data, so ask any provider for seven pieces of evidence.
• A training provider can sell screening as a delivery and records service, but the employer stays responsible for showing a test is valid, so keep licensed ability and personality tools apart from knowledge screens you write yourself.

What is an aviation aptitude test in pre-hire screening?

In pre-hire screening, an aviation aptitude test is a timed, standardized measure of ability, behavior or knowledge, scored the same way for every candidate. UK CAA guidance says psychometric tests broadly measure ability and performance, or personality, preference and style. Ability results may be set against a pass mark, and personality results are usually compared with a norm group.

Three neighbors are often confused with it. A knowledge test checks what a candidate already knows. A licence or rating exam checks competence for a certificate. A clinical evaluation looks at mental health concerns, and the UK CAA’s CAP 1938 guidance on pilot psychological assessment says a pilot psychological assessment is not one. It adds that a suspected mental health problem is a medical matter for the aeromedical examiner or the company medical advisor.

Do regulators require an aviation aptitude test before hiring?

For EU commercial air transport pilots, the rules require operators to ensure flight crew complete a psychological assessment before line flying, but they name no particular test. For technicians, cabin crew and ground staff, the sources reviewed for this post showed no equivalent aptitude rule, so the employer decides. Check your competent authority.

The pilot rule is point CAT.GEN.MPA.175(b) of the EU Air Operations rules, as replaced by Commission Regulation (EU) 2018/1042. EASA’s explanatory note to Decision 2018/012/R gives the aim as ensuring “reasonable measures are taken so that flight crew members are psychologically suitable for CAT operations” (quoted).

CAP 1938 (April 2020), written for UK operators, quotes the requirement as “Identify psychological attributes and suitability of the flight crew in respect of the work environment” (quoted). It summarizes the acceptable means of compliance, AMC1 CAT.GEN.MPA.175(b), in four points:

• The assessment should rest on a job analysis.
• It should cover at least cognitive abilities, personality traits, operational and professional competencies, and social competences.
• It should fall within the 24 months before line flying, unless the operator can show an older one is still adequate.
• A psychologist with aviation knowledge should perform it or oversee it.

On tools, the same guidance states “Using a psychometric assessment tool is not mandatory” (quoted). So the rule leaves you to decide which instrument, which norms, where the pass mark sits and what happens after a weak result. This post relies on the UK CAA’s summary of the AMC. Read the current AMC and GM on EASA’s website, and note that rules of the FAA, India’s DGCA and other authorities were not reviewed here.

What can an aptitude assessment show, and what can it not?

An aptitude assessment can give every candidate a comparable score on a defined ability or profile. It cannot show how a person will behave in a real crew, whether they are medically fit, or whether they will hold a licence. Each tool answers one narrow question, and a hiring file needs several.

The table below, which is my own framework drawn from CAP 1938 and the FAA review cited in the next section, shows what each common component can support and where it stops.

For maintenance roles, start from a job analysis of the actual tasks, such as reading technical documentation, using tools and fault-finding, not from a test catalog. If your offer includes interviews or work-sample ratings, calibrate your assessors as described in examiner standardization and assessor calibration.

What evidence should you ask a test provider for?

Ask for seven pieces of evidence: a job analysis, measurable performance criteria, reliable and valid predictors, a validation study, a documented pass mark, a fairness analysis and written documentation. They come from a 2019 FAA review of pilot selection, which found public evidence of several of them missing.

That review, Best Practices in Pilot Selection (Broach, Schroeder and Gildea, FAA Civil Aerospace Medical Institute, report DOT/FAA/AM-19/06, February 2019), examined 15 test batteries and selection processes from two US airlines and several foreign airlines, using public information only. The table turns its seven practices into questions for a provider and notes what it found.

The review covers pilots, uses public information and dates from 2019, so practice may have changed. Nothing in the seven practices depends on a cockpit, though. The authors also agree with IATA’s 2012 conclusion that pilot selection programs do not appear to have a strong scientific basis, which is a reason to question every provider.

Pro tip: Ask For The Pass-Mark Rationale Under NDA. The FAA review links the lack of public cut-score information to confidentiality, so candidates cannot game the test. You can still ask the provider to share how the pass mark was set and when it last changed, under a confidentiality agreement, and to put the answer in writing.

How do you check an aviation aptitude test for adverse impact?

Compare pass rates between groups. Under the US Uniform Guidelines, a selection rate below four-fifths (80 percent) of the highest group’s rate is generally treated as evidence of adverse impact. It is a screening rule, not a verdict. A flagged test can stay in use if it is valid and no equally valid, less impactful option exists.

The FAA review describes the rule in those terms. EEOC guidance on employment tests (issued December 1, 2007, and without the force of law) adds that a test with adverse impact must be “job-related and consistent with business necessity,” and that employers remain responsible for validity even when a test vendor supplies supporting documentation (quoted phrase; the rest paraphrased).

The table is a worked example with invented numbers. It shows the arithmetic: divide the lower pass rate by the higher one, and compare the result with 0.80.

A ratio of 0.75 falls below 0.80, so this test would be flagged for review. The next steps are to examine the evidence for the pass mark, the job relevance of each section, and whether a less impactful alternative would work as well. Do not simply move the cut score. The FAA review says a pass mark should match the lowest acceptable job performance and that changes should be documented.

Small groups swing the ratio widely, so treat one flag as a prompt to investigate. Outside the US the legal test and statistics differ, so ask counsel in your country. Run the check on the pilot cohort and again each intake, and store pass rates by group next to the form version.

How do accommodations and candidate data fit in?

Treat accommodations and data handling as part of test design. In the US, EEOC guidance says tests should show the skill being measured, not the candidate’s impairment, and that employers must provide reasonable accommodations in test administration unless that causes undue hardship. UK CAA guidance covers consent and data storage.

CAP 1938 says sharing an earlier assessment with another operator needs the candidate’s consent, and that a candidate may refuse without being penalized in selection. It also says records must be stored and protected in line with GDPR. For screen, timing and extra-time settings, see accessible online exams and WCAG basics for training providers. Let candidates request adjustments before test day, and record each request and decision.

How can a training provider offer pre-hire screening to airlines and MROs?

A training provider can offer pre-hire screening as a managed service: it hosts the branded test, schedules candidates, delivers it securely and returns scores to the employer, while a qualified publisher supplies any ability or personality instrument. The employer remains responsible for showing the test is valid for its jobs.

Three offers fit a training provider:

• Intake screening for your own courses. You make the decision and hold the outcome data for ab initio or technician cohorts.
• Managed pre-hire delivery for a client. You run sessions and report scores, and the airline or MRO owns the hiring decision. Contract and pricing points are in selling assessment as a service to corporate clients.
• A knowledge screen for experienced hires. Build it from your own item bank against the client’s job analysis, and set the pass mark with a documented method, as in how to set cut scores for professional training courses.

Keep ability and personality instruments licensed from their publishers. CAP 1938 notes that some suppliers require a British Psychological Society qualification or tool-specific training, and it advises caution about tools with no licensing or certification requirement. A provider without a qualified test user should not score or interpret those instruments.

Pro tip: Log Screening Scores Next To Course Outcomes. The FAA review found the main performance measure in the batteries it studied was pass or fail in training. A training provider already holds that outcome. Store each screened candidate’s scores with the later course result, with consent and a retention rule, so a validation study can use your own data.

What should your assessment platform handle for pre-hire work?

A pre-hire program needs candidate records kept apart from trainee records, per-candidate timing for accommodations, locked form versions, retake rules, retention and deletion controls, and an export of pass rates by group. Check each one in a demo instead of assuming it.

SimpliAssess’s features page lists item banking, test management, examinee management, schedule management, analytics and reporting, and white-label brand control. Its published pages do not describe pre-employment use, norm groups, adverse impact exports or proctoring, so ask for those directly. Its FAQ says data ownership stays with the customer, who can access, modify or delete it.

What should you do next?

Write a one-page job analysis for one role, such as line maintenance technician or first officer cadet. List the tasks, the knowledge needed and the training outcome you will treat as success. Every row of the evidence table hangs from that page.

Then send the seven-practice table to the provider you are considering, and run the four-fifths calculation on your pilot cohort before widening use. After the offer, training and currency tracking are a different job. SimpliTrain’s aviation industry page describes “a comprehensive training tracker and certification monitor” with expiry alerts, and it does not describe recruitment screening.

Frequently asked questions

What is an aviation aptitude test?

An aviation aptitude test is a standardized pre-hire assessment that measures abilities, and sometimes personality or knowledge, relevant to aviation work such as piloting, maintenance or ground operations. Employers use the scores alongside interviews and qualification checks. It is not a licence exam, and it is not a clinical or medical assessment.

Do airlines have to use aptitude tests?

No test is required by name. For EU commercial air transport, the Air Operations rules require a psychological assessment of flight crew before line flying, and UK CAA guidance says using a psychometric tool is not mandatory. Rules for other roles and other authorities differ, so check your competent authority.

Can an aptitude test predict who will succeed in pilot training?

Some can, but only with evidence. UK CAA guidance says a tool should be shown to predict job or training performance for the relevant population. A 2019 FAA review found the test batteries it examined showed evidence of reliability and useful validity, with pass or fail in training as the main measure. It does not endorse any named test.

What is the four-fifths rule in hiring tests?

The four-fifths rule is a US rule of thumb under the Uniform Guidelines: a selection rate below 80 percent of the highest group’s rate is generally treated as evidence of adverse impact. It flags a test for review, not for automatic removal. Small samples and other facts can change the picture, so involve counsel.

Can a training provider run pre-hire tests for an airline or MRO?

Yes, as a delivery and records service with a clear contract. EEOC guidance says employers remain responsible for validity even when a vendor supplies documentation. A provider also needs qualified users for licensed instruments and clear data-handling terms, and it should not describe its service as approved or certified by any authority.

Do candidates with disabilities need accommodations on aptitude tests?

In the US, EEOC guidance says employers must provide reasonable accommodations in test administration unless doing so would cause undue hardship, and tests should show the skill measured, not the impairment. Other countries have their own rules. Let candidates request adjustments before test day and record each request and decision.
