1.1 Current Exam Facts

The FAA Private Pilot — Airplane knowledge test is not a generic “pilot written.” It is one specific airman knowledge test with the test code PAR. You sit it on a computer at an authorized PSI testing center. The items are multiple-choice. They are written to the Private Pilot for Airplane Category Airman Certification Standards. A passing result is a legal prerequisite for the practical test. It is not a pilot certificate by itself, and it does not authorize solo.

Official PAR numbers (use the testing matrix)

The document a PSI proctor actually applies is the FAA Airman Knowledge Testing Matrix. The October 22, 2025 revision — the current matrix as of this writing — lists PAR as follows. Memorize these four logistics numbers the way you memorize V-speeds.

Those figures describe the real exam, not the size of any local practice inventory. seo.totalQuestions language and this guide’s “60” always mean the official PAR form. A 100-question practice bank is study inventory. It is not the FAA test.

The 2.5-hour trap and validation items

Until April 24, 2023, PAR really was a 150-minute test. FAA Airman Testing Community Advisories from February and April 2023 announced that a psychometric review of PAR (and the commercial airplane test, CAX) had finished, that the topics did not change, and that allotted time would drop from 150 minutes to 120 minutes that Monday. The current matrix still shows 2.0 hours.

The trap is that FAA-S-ACS-6C’s own appendix knowledge-test table still prints 2.5 hours. That appendix row is stale. Use the testing matrix for time, scored-question count, age, and passing score. Use ACS-6C for what you must know. If a 2022 blog, a laminated ground-school card, or even the ACS appendix says 2.5 hours, treat the time figure as outdated.

The same 2023 advisories explained that five unscored validation questions may be added, so the screen count can look like 65. The matrix is explicit on two points: the listed “NUMBER OF QUESTIONS” (60) does not include validation items, and the listed allotted time does include time to answer them. You will not be told which items are validation. Do not confuse “I clicked through about 65 screens” with “the official test is 65 scored questions.” Validation items do not count for or against the 70 percent score.

Sixty official items versus a 100-question practice bank

Prep products often bank about 100 PAR-style items so you can drill ACS knowledge more than once. That inventory is a study tool. It is not the official exam length, and it is not a leaked FAA form. The FAA does not publish the live item pool. Anyone who tells you “the real written has 100 questions” is describing a practice product, not PAR.

You need 42 scored correct answers to hit 70 percent. A 68 percent is a fail. There is no FAA curve, no “almost passed” endorsement, and no extra credit for finishing early.

Three ages that are not the same number

These ages are repeatedly swapped on oral quizzes. Keep them separate.

• 15 — testing-matrix minimum age to sit PAR. 14 CFR 61.35(a)(3) also requires identification showing you meet, or will meet before the AKTR expires, the age for the certificate sought. The matrix’s “15” is the number the proctor enforces at check-in.
• 16 — typical minimum age to solo an airplane. 14 CFR 61.83 sets student-pilot eligibility at 16 for airplanes (14 for glider or balloon). 14 CFR 61.87 is the solo rule itself: an instructor-given pre-solo knowledge test, the listed maneuvers, and a 90-day make-and-model endorsement. Sixteen is the solo age; 61.87 is the solo process.
• 17 — 14 CFR 61.103(a) minimum age to be issued the private certificate in an airplane (16 for glider or balloon).

A 15-year-old with a proper endorsement can legally take PAR. That passing AKTR then sits on the 24-calendar-month clock while the student finishes dual and solo. The private certificate still cannot be issued until 17. Claiming “there is no minimum age for the written” is a miss. So is assuming you must already be 17 to walk into PSI.

Endorsement, English, identification, and fee

14 CFR 61.35(a)(1) and 61.103(d) require an authorized instructor’s endorsement that you completed the applicable ground training or home-study course on the 61.105 knowledge areas and are prepared for the knowledge test. A certificate of graduation from an FAA-certificated pilot school under 61.71(a) also works. Conversion tests such as PCP do not need that endorsement. PAR does. Arriving with only a student-pilot certificate and no knowledge-test signoff is a wasted appointment.

61.103(c) requires you to read, speak, write, and understand English. That is certificate eligibility, not a PSI courtesy.

Bring acceptable identification: photograph, signature, date of birth, and a physical residential address. A post-office box is not a residential address. If you are under 18 and lack an acceptable ID, a parent or legal guardian may accompany you, present their own ID, and attest to your identity. Create an IACRA profile and obtain your FAA Tracking Number (FTN) before test day; the FTN prints on the AKTR.

The testing fee is a PSI fee, not a number written into 14 CFR. PSI’s organizational voucher price has been $175 per airman knowledge test (plus applicable tax). Individual scheduling can differ by center and date. Treat about $175 as the working figure and confirm the live amount when you book on the PSI FAA site. If the posted fee has moved, the posted PSI figure controls — not a blog and not this paragraph.

Pass, fail, and the 24-calendar-month clock

A passing PAR result counts for the practical test only if you passed “within the 24-calendar-month period preceding the month the applicant completes the practical test” (14 CFR 61.39(a)(1)(i)). FAA’s recreational-and-private knowledge-test page says the same thing in calendar-month language: the result expires 24 calendar months after the month you took it. Pass on 14 August 2026 and you must finish the checkride in or before August 2028. Miss that window and you retake PAR. The AKTR is not a certificate and it does not “stay good until you fly.”

If you fail, 14 CFR 61.49 is blunt. You may reapply only after an authorized instructor has given additional training, determined you are proficient to pass, and endorsed you. The matrix allows that endorsement as a signed statement, a logbook notation, or the Authorized Instructor’s Statement on the failed AKTR. You must present the failed AKTR at retest; the proctor scans it and destroys the paper. Do not invent a 14-day PAR waiting period. That 14-day rule belongs to other tests (for example UAG), not to PAR when you have the 61.49 endorsement.

The AKTR lists ACS codes for missed areas whether you passed or failed. PAR is an ACS-coded test. Those codes travel with you to the instructor and the designated pilot examiner. Section 1.2 teaches how to read them.

The right airplane test — not sport, recreational, or helicopter

PAR is Private Pilot Airplane. Adjacent codes that students book by accident include:

• PRH — Private Pilot Helicopter (60 questions, age 15, 2.0 hours). Different ACS, different aircraft.
• SPA — Sport Pilot Airplane (40 questions, 2.0 hours).
• RPA — Recreational Pilot Airplane (50 questions, 2.0 hours).
• PAT — Private / Recreational transition (30 questions, 1.5 hours).

The testing supplement for this family is FAA-CT-8080-2H (Sport Pilot, Recreational Pilot, Remote Pilot, and Private Pilot). FAA has begun embedding some Private Pilot figures on the screen. You should still know how the supplement’s legends, performance graphs, and sample sectional excerpts work.

Scenario: Maya at the PSI desk

Maya is 16. She has a 61.103(d) endorsement dated last week, a state driver’s license with her home street address, and her FTN. She asks for “the private pilot written.” The proctor’s screen offers PAR and PRH. She is training in a Cessna 172, so PAR is the only correct code. She has two hours, not two and a half. She should expect 60 scored items and possibly a handful of unmarked validation items. If she scores 70 percent, she walks out with an AKTR that is good for 24 calendar months — long enough to finish solo (she is already 16) and to take the checkride after she turns 17. If she scores 68 percent, she does not “almost” have a written. She needs 61.49 training, a new endorsement, and a new sitting. If she had shown up without the endorsement, the proctor would have been required to turn her away, fee or no fee.
