IDAC Air Traffic Controller (CTA) exam-day guide
IDAC Air Traffic Controller (CTA) · Prepare for the day ahead.
Your checklist
Government-issued photo ID and admission document
Bring the original photo ID required for admission plus any confirmation letter or admission ticket the test centre issued. The exact ID types accepted, and whether a second form is required, vary by provider and country, so confirm with the provider before travel. A photocopy or a photo on your phone is normally not accepted.
Appointment confirmation with time, address and entry instructions
Save the confirmation offline on your phone and print one copy. Check the street entrance, building, floor and any security-desk procedure, because large test centres often have several entrances and a check-in desk that closes before the appointment time. Confirm with the provider how early you must arrive.
Travel plan with a backup route and buffer time
Plan to reach the area well before your appointment, with a second route in case of rail disruption or roadworks. Traffic delays are a common cause of refused admission, and late arrival rules are set by the provider, so confirm with the provider whether late candidates can still sit the test.
Provider rules on personal items and storage
Find out in advance what you may take into the test room and whether lockers are available for bags, phones and watches. Many aviation selection tests prohibit phones, smart watches and notes in the testing area. Do not assume storage is provided; confirm with the provider.
Permitted aids: calculator, pen, water, medication
Ask the provider which aids are allowed. Some aptitude batteries supply an on-screen or provided calculator, while others prohibit any calculator. If you need medication, glasses, hearing aids or other aids, confirm the approval process with the provider in advance rather than on the day.
Rest, hydration and a normal meal before the test
Aptitude and cognitive tests are sensitive to fatigue. Sleep normally for the two nights before the test, avoid heavy alcohol, and eat a normal meal so you are not hungry or over-caffeinated. Do not try a new energy drink or supplement on exam day.
Practice the test interface and question format in advance
Use only the familiarisation material the provider publishes, plus general practice on the underlying skills: mental arithmetic, spatial reasoning, attention to detail and multitasking. Do not memorise answers from unofficial question banks, because the live test is likely to differ and guessing from a memorised key wastes time.
Prepare your personal history and documents for any interview or medical stage
Some selection processes combine the computer-based test with an interview, document check or medical questionnaire on the same day. Confirm with the provider which stages are scheduled and what supporting documents, certificates or records you must bring.
Know the scoring and retake rules before you sit
Ask the provider how each subtest is scored, whether there is a minimum per subtest or only an overall threshold, and whether failed subtests can be retaken and after what waiting period. These rules are provider-specific; confirm with the provider and do not rely on forum reports.
Plan the day after the test
Do not schedule tight commitments immediately after the test. Some batteries are long, and results or next-stage invitations may arrive with short notice. Leave the evening free and keep your phone and email reachable in case the provider contacts you.
Check the provider's current policy on illness, cancellation and rescheduling
If you are unwell, contact the provider before the appointment rather than attending and underperforming. Cancellation, rescheduling and no-show rules differ between providers and may involve fees; confirm with the provider. needs_review
Verify the test language and any accommodations
Confirm the language in which the test is delivered and whether translated instructions or extra time are available for a documented need. Accommodation requests usually need approval before the test date, so confirm with the provider. needs_review
Plan the day
Re-read the admission letter and confirm the exact address, arrival time and ID requirements. Check that your ID is valid and not expired, and that the name matches your booking. Print the confirmation and save an offline copy. Confirm with the provider if anything in the instructions is unclear.
Do a final, light practice session on the skills the test measures, such as timed mental arithmetic, instrument-style spatial reasoning and sustained attention. Stop heavy practice at least 48 hours before the test; last-minute cramming tends to raise anxiety without improving aptitude scores.
Plan the journey in detail: route, departure time, backup route, parking or public transport, and the building entrance. Decide what you will carry and check the provider's list of prohibited items so you are not surprised at check-in.
Adjust your sleep schedule so you are awake and alert at the appointment time. If the test is early, shift bedtime earlier over these three nights rather than relying on one early night.
Lay out ID, confirmation, permitted aids and clothing the night before. Charge your phone but plan to switch it off or store it as required. Pack water and a snack for after the test, not for the test room unless the provider allows it.
Do a short review of test structure only: how many subtests, their order, time limits and whether there are breaks. Do not attempt new practice tests late in the day. Confirm with the provider if the schedule or timing is not stated in your admission materials.
Eat a normal dinner, avoid alcohol, and go to bed at your planned time. Avoid intense screen use late in the evening. If you feel unwell, check the provider's illness policy now rather than on the morning of the test.
Eat a normal breakfast and drink a moderate amount of water. Avoid excessive caffeine if you are not used to it. Arrive at the test centre with the buffer you planned; being early reduces stress and protects against refused admission for lateness.
Follow check-in instructions exactly: present your ID, store prohibited items as directed, and listen to the invigilator's briefing. Ask the invigilator about anything unclear, such as break rules or how to flag a technical problem, before the test starts.
Read each instruction screen carefully before starting a timed section. Work steadily and do not dwell on a single item; unanswered items usually score the same as wrong answers, so attempt every item within the time available. Use any on-screen tutorial or practice items to learn the controls before the scored section begins.
Manage your attention deliberately. In multitasking or attention tasks, keep a consistent scan pattern rather than reacting randomly. In timed arithmetic, use rough estimation where the answer options allow it, and check units and signs before submitting.
If equipment fails, the screen freezes or you feel unwell, raise your hand and tell the invigilator immediately. Do not attempt to fix equipment yourself. Note the time and the subtest so the incident can be recorded; ask the invigilator how the incident will be handled.
Take only the breaks the provider permits and return on time. Use breaks to stand, drink water and reset attention rather than to review questions. Do not discuss test content with other candidates, because that may breach the provider's conduct rules.
Follow the provider's instructions on leaving the centre and returning materials. Ask when and how results will be communicated, and what the next stage involves. Do not post detailed test content online; confirm with the provider what you may and may not disclose.
Rules to check
Bring the original photo ID specified by the provider and present it at check-in. If your ID is expired, damaged or bears a different name from your booking, contact the provider before the test date; admission may be refused and the decision rests with the provider.
Arrive by the time stated in your admission materials. Late arrival, rescheduling and no-show rules are set by the provider, so confirm with the provider in advance rather than assuming you will be admitted late.
Follow all invigilator instructions and the provider's conduct rules. Do not bring unauthorised notes, phones, smart watches or other devices into the testing area, and do not attempt to record, photograph or share test content.
Do not communicate with other candidates about test content during the session or afterwards in a way that breaches the provider's confidentiality rules. If you are unsure what may be discussed, confirm with the provider.
Attempt every item unless the instructions say otherwise. In most timed aptitude batteries there is no penalty for a wrong answer beyond the lost mark, so leaving items blank usually lowers your score; check this in the instructions.
Breaks are only those the provider schedules or permits. If you need to leave the room for illness or another reason, attract the invigilator's attention rather than leaving unannounced; the provider decides whether the test can continue.
Scoring methods, minimum thresholds and retake eligibility are provider-specific. Ask the provider how results are reported and whether and when you may retake a subtest; do not rely on unofficial accounts.
If you have a disability, medical condition or other need requiring an accommodation, request it before the test date and follow the provider's approval process. Accommodations are unlikely to be arranged on the day.
