FAA written practice test facts before you schedule PSI

Searchers looking for a "FAA written test practice" page usually need more than a question bank. This guide pins the current Private Pilot Airplane PAR rules next to the IRA, CAX, and UAG routes students confuse with it: question count, allotted time, passing score, 24-calendar-month validity, and what the Airman Knowledge Test Report means after a miss.

PAR test code
60 questions

Private Pilot Airplane: age 15 minimum, 2.0 hours, 70 passing score.

Result clock
24 calendar months

A passing knowledge-test report expires after the month it was taken.

Retest packet
AKTR + endorsement

After a failed test, bring the failed AKTR and instructor retest endorsement.

Pick the right test code

PAR is the airplane private pilot written test; Part 107 students should use UAG, and instrument students should move to IRA once the private-pilot fundamentals are stable.

Treat 24 months as a checkride clock

A passing report starts a 24-calendar-month window. Schedule the written early enough to guide training, but not so early that weather and maintenance delays burn the practical-test window.

Turn missed ACS codes into drills

After the FAA test, the AKTR prints deficient codes. Use those codes to target handbook, FAR/AIM, and oral-exam practice before the instructor signs the retest or checkride review.

FAA Written Test FAQ
Q1Which FAA written practice test should a private pilot student take first?
Start with the PAR Private Pilot Airplane bank if you are training for an airplane private pilot certificate. GroundScholar separates the written-test drill from checkride oral prep so PAR weak areas do not get hidden behind unrelated scenario practice.
Q2How many questions are on the FAA private pilot written test?
The FAA Airman Knowledge Testing Matrix lists PAR Private Pilot Airplane as 60 scored questions, 2.0 hours allotted, age 15 minimum, and a 70 passing score.
Q3How long is the FAA written test good for?
A satisfactory FAA knowledge test expires 24 calendar months after the month you took it. If the practical test is not completed in that window, you need another knowledge test.
Q4What do I need to schedule or retake an FAA written test?
The FAA testing matrix requires identification, an FTN in IACRA, and the applicable authorization. For PAR, acceptable first-test authorization includes a pilot-school graduation certificate, instructor endorsement, or home-study course completion certificate; retests after failure require the failed AKTR plus an instructor endorsement.
Q5Which practice test should I use for the instrument written test?
Use the IRA Instrument Rating Airplane practice test if you are adding an airplane instrument rating. The current FAA matrix lists IRA as 60 questions, 2.0 hours, age 15 minimum, and a 70 passing score.
Q6What is the CAX written exam?
CAX is the Commercial Pilot Airplane knowledge test. The FAA matrix lists 100 scored questions, 2.5 hours allotted, age 16 minimum, and a 70 passing score, so commercial students should not use a PAR-only practice set.
