How this list was compiled: Our own questions, written to the seven content areas of the Damage Analysis and Estimating (Test B6) test specifications and task list in the ASE Collision Repair and Refinish Study Guide (copyright 2026, https://ase.com/wp-content/uploads/ASE_Collision_Study_Guide.pdf, opened 2026-10-14): damage analysis 11 of 50 scored questions, estimating 13, legal and environmental practices 3, vehicle construction 6, vehicle systems knowledge 11, parts identification and source determination 4, customer relations and sales skills 2. The bank holds the same 11, 13, 3, 6, 11, 4 and 2. Every fact was read in the public text the question names: 49 CFR 565.15, 567.4, 541.5, 580.5, 571.111 and 571.138 and 40 CFR 82.154 at ecfr.gov, and Wikipedia articles on body construction, materials, glass, restraints, driver assistance sensors, insurance terms and parts sources (texts fetched 2026-10-13). Four estimating questions are arithmetic: each states its own rates and rules, and its answer was worked twice. The sample questions printed in the study guide were not used.

Read the full guide

Seven content areas, 50 scored questions

ASE's Collision study guide gives estimating 13 questions, damage analysis 11 and vehicle systems knowledge 11. Vehicle construction has 6, parts identification and source 4, legal and environmental practices 3, and customer relations and sales skills 2.

An ASE B6 study guide in question form

Each answer names its source: the federal VIN, certification label and parts marking rules, FMVSS No. 111 and 138, EPA and odometer rules, and Wikipedia for body construction, materials, sensors, insurance terms and parts. Four estimating questions are arithmetic, with their own rates.

  • Estimating and damage analysis are 24 of the 50 questions. Start there.

Questions and answers

How many questions are on the ASE B6 test?

ASE's 2026 Collision study guide lists 60 questions in 75 minutes: 50 scored and 10 that are not counted. The recertification test is 25 questions in 30 minutes.

Is there an official ASE B6 study guide?

Yes. ASE's free Collision Repair and Refinish Study Guide covers tests B2 to B6. Its B6 pages hold the test specifications, the task list and six sample questions. None of those questions is used here.

Does B6 count toward Master Collision Repair and Refinish Technician?

No. ASE's study guide marks B2, B3, B4 and B5 as required for that recognition. B6 is a certification of its own for damage estimators.

What work experience does ASE B6 certification require?

ASE's B6 page asks for a passed test and proof of two years of work experience specifically related to damage analysis and estimating. Hands-on collision repair does not count toward it.
