ASE Task Lists › B4
The ASE B4 Task List
All 50 official tasks on the Structural Analysis and Damage Repair test, as ASE publishes them. This is exactly what you are graded on.
What is actually on the ASE B4 test
ASE publishes a task list for every certification: the specific jobs a technician is expected to be able to do. The test is built from that list, and the number of questions in each content area is fixed. Below is every task on the official list, together with how many questions each content area carries so you can see where your study time pays off.
50 scored questions across 4 content areas and 50 tasks. The live test also includes a small number of unscored pilot questions that do not count toward your result.
