How many questions are on the BCaBA exam?
175 multiple-choice questions: 150 count and 25 are unscored. Each has 4 answer choices, just 1 of them correct, and all are equally weighted, by the BCaBA Handbook.

Up to 8 attempts within the 2-year period after the application is approved, with a wait of 30 days after each attempt and a new retake application each time, by the BCaBA Handbook.
What is the passing score for the BCaBA exam?
The BACB sets it with the modified Angoff method: BACB-certified subject matter experts on a panel determine the score and the Board of Directors approves it. A new passing score follows a new test content outline.
