How to read an ABA exam pass rate

Read the count with the percentage

A 100% result from ten candidates and a 90% result from hundreds describe different amounts of evidence. Small cohorts can change sharply from one year to the next. Our tables put candidate counts beside every percentage so you can decide which comparisons are useful.

Compare the same program entry

One institution may have separate entries for campus, online, and certificate programs. The reported result belongs to that entry. It should not be presented as the result for every course offered by the institution.

Check the year and requirements

The BCBA table uses 2024 results, and the BCaBA table uses 2024 results. Some marked entries pool multiple years, listed on the entry. RBT outcomes are from 2025. These are historical outcomes, not a guarantee about a course you enroll in today. RBT requirements changed in 2026, and BCBA and BCaBA requirements change in 2027. Confirm the requirements that apply to your intended application date.

Ask what the percentage leaves out

Tuition, completion rates, student support, fieldwork access, and the experience of candidates are separate questions. Exam pass rates alone cannot tell you which program is best for your circumstances.
