What If Your ATP Written Exam Score Expires Before Your Checkride?

The validity window pilots often overlook

An FAA knowledge test result, including the ATP written exam, is valid for 24 calendar months from the date you take it. That means the practical test (checkride) for the associated certificate or rating must be completed before the end of the month, 24 months later, in which the test was taken, or the score no longer satisfies the aeronautical knowledge requirement for that certificate.

This timeline can sneak up on pilots who complete the ATP-CTP and the written exam early, then spend a year or more building the remaining flight hours needed to meet the 1,500-hour total time requirement, only to realize their scheduling window for the checkride is tighter than they assumed once other life events, hiring timelines, or training slots get factored in.

What happens if the 24 months run out

If your knowledge test result expires before you complete the checkride, the test result simply becomes invalid for certification purposes. It does not carry a penalty beyond the practical reality that you must retake the written exam before your practical test can be conducted, since the FAA requires a current, valid knowledge test result on file at the time of the checkride application.

There is no waiver or extension process for an expired knowledge test result. The only path forward is retesting. For the ATP written specifically, this also means confirming that any prerequisite training tied to the exam, such as the ATP-CTP, is still recognized as satisfying the training requirement, since the CTP graduation certificate itself does not expire the same way the written score does, but you'll want to verify current guidance with your training provider and testing center before scheduling a retest.

Why this matters more for ATP candidates specifically

The ATP written exam sits behind a mandatory prerequisite, the ATP-CTP, which most candidates complete as a 6- to 8-day course covering 32 hours of academic ground training and 10 hours of simulator training. Because that course has to be scheduled, attended, and completed before you're even eligible to sit for the written, candidates sometimes complete the CTP and written well before they've finished accumulating flight hours or secured a class date for type rating and airline training.

That gap between finishing the written exam and reaching the checkride is exactly where the 24-month clock becomes relevant. If you're early in flight time accumulation when you complete your CTP and written, it's worth mapping out a realistic timeline for hours, hiring, and training to make sure the checkride happens comfortably inside that window rather than right up against the deadline.

• Knowledge test results are valid for 24 calendar months from the test date
• The checkride must occur before that window closes, not just be scheduled
• There is no extension or waiver — an expired score requires retesting
• Track your CTP completion date against your projected flight-hour and hiring timeline

Practical steps to avoid the problem

Treat your knowledge test date as the start of a countdown, not a completed milestone. Write the 24-month expiration date somewhere you'll actually see it, and revisit your flight-hour progress and airline application timeline against that date periodically rather than assuming things will line up.

If you can see that your hour-building or hiring process is going to take a long time, some candidates deliberately delay taking the written exam until they're closer to being eligible for the checkride, rather than completing it as early as possible. There's no single right answer here — it depends on your personal timeline — but it's a conversation worth having with your training provider before you schedule the CTP.

If you do need to retest

Retaking the ATP written after an expiration isn't a disciplinary event or a mark against your record in the way a checkride failure can feel. It is simply a scheduling and knowledge-currency requirement. Most candidates who retest after a gap benefit from a structured review of current regulations and procedures rather than trying to recall study materials from years earlier, since testing standards and question banks are updated periodically.

If you're approaching your 24-month window or unsure where you stand, it's worth reaching out to a training provider to confirm your specific dates and plan the remaining steps toward your checkride.
