Notes on how to study for the BCBA exam, grounded in the research on how people actually learn, and honest about what the evidence does and doesn’t say.
Here is the thing almost nobody tells you first: retake candidates pass the BCBA exam at about 23%, against 51% for first-time candidates — less than half the rate. Part of that gap is unavoidable, but a large part of it is method, because the most common retake plan is to study the same material the same way, and material you have already studied feels even more familiar the second time through.
Before you study, know these six things: the exam is 185 questions of which only 175 are scored, there is no fixed passing percentage because scores are scaled, you receive almost no feedback if you pass and a detailed breakdown if you fail, you have eight attempts inside a two-year window, the nine content areas carry very different weights, and the exam tests judgment on scenarios rather than recall of definitions. Each one has a consequence for how you prepare.
The five study habits with the strongest research behind them are: test yourself instead of rereading, spread your sessions across weeks instead of stacking them, mix domains within a session, aim your time at your weakest areas, and practice with scenarios instead of definitions. Every one of them feels worse than what it replaces, which is exactly why most people do not do them.
