The FAA sample questions and Airman Knowledge Test Reports may contain two types of coding. This is determined based on the availability of a published Airman Certification Standards (ACS) for the particular test in which you are taking.

1. The Learning Statement Code (LSC) associated with question topic areas. The Learning Statement codes currently appear on the Airman Knowledge Test Report for any missed knowledge test questions for which an Airman Certification Standards (ACS) is not yet published, and the Practical Test Standard (PTS) remains the guiding document. View the complete list of LSC.
2. The Airman Certification Standards (ACS) code for question topic areas. The ACS codes currently appear on the Airman Knowledge Test Report for any missed knowledge test questions for which an Airman Certification Standards (ACS) has been published.
