FAA Written Test Endorsement: Who Signs It and What It Says

Key facts at a glance

What does the written test endorsement confirm?

It confirms that an authorized instructor has assessed your preparation and considers you ready for the required knowledge test.

For a private pilot applicant, 14 CFR 61.103(d) requires the instructor to have conducted the training or reviewed your home study in the applicable knowledge areas. That makes the endorsement the result of a review. Finishing a book, buying an app or watching every lesson doesn't make the assessment automatic.

Arrange the review before you need the signature. Tell your instructor which test you're taking and how you've prepared, then agree on what they need to see. That gives you time to work through any gaps before your appointment.

Who can sign an FAA written test endorsement?

An appropriately authorized flight instructor or ground instructor can sign for the private pilot knowledge test.

Your flight instructor is one option, and a certificated ground instructor can also help. 14 CFR 61.215 gives both basic and advanced ground instructors the authority to recommend applicants for private pilot knowledge tests. An instrument ground instructor rating alone covers instrument-related knowledge tests. Ground instructors must also meet the recent experience requirements in 61.217.

The important question to ask is simple: "Can you review my preparation for the Private Pilot Airplane knowledge test and provide the required endorsement if I'm ready?"

How do you get an endorsement after self study?

Complete a home-study course covering the required knowledge areas, then have an authorized instructor review your work and assess your readiness.

14 CFR 61.105(a) allows home study as a way to complete the private pilot aeronautical knowledge preparation. The scope matters: your study should cover the applicable areas in paragraph (b), including regulations, weather, navigation, performance, aircraft systems and aeronautical decision-making.

A useful way to prepare for the review is to bring:

1. Your study outline. Show the instructor which materials you used and which knowledge areas you covered.
2. Recent practice results. Include the topics you missed, so the review can focus on the gaps.
3. Worked problems. Bring examples of chart reading, weight and balance, and flight-planning calculations you can explain.
4. Your questions. List any answers you can recognize but still struggle to explain.

These are suggestions for making the review useful, rather than a separate FAA document requirement. Ask the instructor how they prefer to conduct the assessment and what their ground instruction costs.

For example, if your practice scores look good but you repeatedly miss questions about airspace entry, work through a specific flight on a sectional with the instructor. Explaining where you are, what airspace you're entering and what you need before entry gives the review something concrete to test.

Complete your study, have it reviewed, obtain your authorization, then bring it to the testing center.

Can an online ground school provide the endorsement?

Yes, some online courses provide an instructor-signed authorization after you meet their completion and assessment requirements.

Check what the provider actually issues. AC 61-65K describes an industry home-study route that includes a comprehensive exam scored by the provider and a graduation certificate signed by its authorized flight instructor (AC 61-65K, section 10.2). A course dashboard showing "100% complete" is not, by itself, the same document.

Before paying for a course, ask who signs its test authorization, which FAA test it covers, and how you receive it. If you already bought a course, look for the endorsement or graduation document in your account and read the provider's instructions. Ask your testing center ahead of time if you're unsure about its acceptance.

FirstSolo.ai is a study tool and does not issue FAA knowledge-test endorsements. Its practice results can help you identify topics to review, but your test authorization must come from an accepted instructor or school source.

What should the endorsement say?

It should identify you and the intended knowledge test, confirm the required preparation and readiness, and include the instructor's signing details.

The current FAA private pilot sample is A.36 in AC 61-65K. For an instructor reviewing home study, A.86 is also relevant. Have your instructor select and complete the appropriate wording (AC 61-65K, Appendix A).

The FAA's signing guidance distinguishes flight instructors from ground instructors. Have the signer check their own details rather than filling in a flight instructor field for a ground instructor.

Check the applicant, intended test, preparation, readiness and instructor signing details together.

What practice score do you need for an endorsement?

The private pilot endorsement rules do not prescribe a universal practice-test percentage.

The requirement in 61.103(d) is the instructor's determination that you're prepared. An instructor or course provider may set a practice-score requirement as part of its assessment. Ask what that requirement is and what else the review includes.

Use a score as feedback. If you can answer a question correctly but can't explain how a different wind, aircraft weight or airspace boundary would change the answer, spend more time on that topic. A useful review checks whether you can apply what you've studied.

How long is a written test endorsement valid?

The general private pilot written-test prerequisites do not set a blanket expiration period for the initial endorsement.

Neither 61.35(a)(1) nor 61.103(d) specifies one. Read your actual document for any stated validity limit, and resolve questions with the issuer and testing center before your appointment.

After you pass, a different clock matters: the private pilot knowledge-test result generally must fall within the 24 calendar months preceding the month you complete the practical test (61.39(a)(1)(i)). That window runs from the test, not the date your instructor signed the initial endorsement.

What should you check before test day?

Check that you have an accepted authorization for the test you're booked to take and that the document is complete and legible.

For the PAR test, the FAA testing matrix lists a graduation certificate from an FAA-certificated pilot school or a written statement/logbook endorsement from an authorized ground or flight instructor (FAA testing matrix, page 13). Check the document well before the appointment so the issuer has time to correct anything missing.

If your endorsement is in an electronic logbook or course account, ask the testing center how to present it. A printed copy is a useful precaution; follow the center's instructions about originals and copies. Keep the full statement and signing details together.

For an instructor endorsement, check all six items together. A graduation certificate follows the issuing school's format.

Have your authorization ready before booking or leave enough time to resolve it before test day. Our FAA knowledge-test scheduling guide explains the FTN, IACRA and PSI steps.

Do you need another endorsement if you fail?

Yes. After a failure, you need additional training and an endorsement from the authorized instructor who provided it.

Under 14 CFR 61.49(a), the instructor must determine that you're proficient to pass before you reapply. Arrange a review of the deficient areas on your Airman Knowledge Test Report (AKTR), work through the problems and obtain the retest endorsement.

The FAA testing matrix, page 13 also requires the failed report for a retest after failure. Check your documents before paying for another appointment. Your original authorization alone does not cover the additional training and endorsement required after that failure.

Frequently asked questions

Can I get endorsed before starting flight lessons?

Yes. The knowledge preparation can be completed through ground training or home study; you still need the required instructor review and test authorization (61.105(a), 61.103(d)).

Does the endorsement authorize solo flight?

No. This endorsement concerns admission to the knowledge test. Solo flight requires its own training and authorizations, addressed separately in the FAA's endorsement guidance (AC 61-65K, Appendix A).

What if my instructor says I'm not ready?

Ask which topics need work, agree on a study plan and arrange another review. Use the feedback to make the next session more useful.

Does FirstSolo.ai provide endorsements?

No. FirstSolo.ai helps you study; it does not issue endorsements. Arrange your authorization with an appropriately authorized instructor or an accepted school source.
