FAA Test Code Lookup

Missed questions on your FAA knowledge test come back as codes, not topics. Paste the codes from your Airman Knowledge Test Report and see exactly what each one means, so you know what to study before the checkride.

How the codes work

Every code on your test report points to a single knowledge area. Older tests print learning statement codes such as PLT264; newer tests with a published Airman Certification Standards print ACS codes such as PA.VIII.C.K1c. Your instructor is required to review each one with you and endorse the review before you take the practical test. Use the lookup above to translate them, then drill the weak areas.

What is an ACS code?

The FAA is moving from the older learning statement codes (the PLT numbers) to Airman Certification Standards codes. An ACS code is a precise address inside the standard, written as three parts: the Area of Operation, then the Task within it, then the specific Knowledge, Risk management, or Skill element.

Take PA.I.A.K1: PA is the Private Pilot Airplane ACS, I is Area of Operation I (Preflight Preparation), A is the first Task (Pilot Qualifications), and K1 is the first knowledge element under it. Newer test reports print these ACS codes; older ones still print PLT learning statement codes. This lookup handles both.

Preparing for your checkride deficiencies

The codes on your report are not just a score, they are the agenda for the next step. Under 14 CFR 61.39, an authorized instructor must review each area you missed and endorse that review before you take the practical test, and the examiner will revisit those areas during the oral.

So work the list in order: translate each code above, study the underlying topic in the FAA handbook it comes from, and be ready to explain it out loud, not just recognize the right answer. That is the difference between passing the written and being ready for the checkride.

Browse every code

All 916 learning statement codes from the FAA reference guide, grouped by test family. 519 now have a full plain-English breakdown (linked); we are adding more. Use your browser find (Ctrl or Cmd + F) to jump to one.

Common questions

What are the codes on my FAA knowledge test report?

When you miss a question on an FAA Airman Knowledge Test, your test report lists a code for the knowledge area behind it. Older tests use learning statement codes (like PLT005); tests with a published Airman Certification Standards use ACS codes (like PA.I.A.K1). Your instructor reviews each code with you before the practical test.

How do I use this lookup?

Type or paste the codes from your test report into the box above and select Look up codes. Each recognized code shows the FAA learning statement it stands for, so you know exactly what to review.

Where do the code definitions come from?

They are taken verbatim from the FAA Learning Statement Reference Guide for Airman Knowledge Testing (AFS-600), which is public domain. It covers pilots, instructors, flight engineers, dispatchers, parachute riggers, inspection authorization, and aircraft mechanics.
