Prepare for your ASTB-E

OAR uses Math Skills, Reading Comprehension and Mechanical Comprehension. The full ASTB-E also includes Aviation and Nautical Information, the Naval Aviation Trait Facet Inventory and Performance Based Measures. Aviation applicants need the full battery; confirm the requirement for your officer program.

Navy guidance estimates about 2 hours to 3 hours 15 minutes for the full ASTB-E, and 1–2 hours for OAR. Official adaptive question counts can vary. Our full practice uses 84 knowledge questions, a short unscored trait familiarization and a sequence of performance tasks. Its counts and clocks are original preparation settings.

One ASTB pass covers its math, reading, mechanical, aviation and nautical drills, performance drills, replays and full practice. Accounts with free first attempts can try each short drill once. The public study guide and examples are free, and saved results remain available after a pass expires. The separate OAR product is not unlocked by an ASTB pass.

Knowledge answers and explanations appear after the full sitting ends. Short knowledge drills explain each submitted answer. Performance tasks show the movement and signals needed to play; their results are reviewed afterward. Trait familiarization has no correct answers or score.

Use a desktop or laptop and stereo headphones for listening and combined performance practice. Check the controls supported on the practice setup screen and complete its calibration. Browser controls can teach the task but do not reproduce the motor demands of the Navy’s test-center equipment. You do not need to buy equipment to read the guide or work on knowledge questions.

Choose the statement that describes you more closely. The six original pairs here introduce the format; there is no ideal answer key, trait score or suggested pilot profile. We do not save your choices. Full practice records only that familiarization was completed.

Official results include an OAR score from 20–80 and AQR, PFAR and FOFAR scores from 1–9. Requirements depend on the program and current selection criteria. Practice accuracy and performance measures are learning feedback; we do not convert them into official scores or predict selection.

Current Navy guidance allows three Series-E attempts and requires 30 full calendar days after completion of the full battery before another full attempt. A full-battery retest repeats the battery, and scores cannot be combined across attempts. The most recent scores replace earlier scores even if lower. Confirm your eligibility and appointment with the testing office.

The Navy does not permit a calculator and supplies relevant formulas and scratch materials. Adaptive questions cannot be skipped or revisited. Our knowledge practice also moves forward after each submitted answer. Use the original formula reference to learn the method, then practice calculations without a calculator.
