ABA board exam — how long did you study and what did you prioritize?

Twelve weeks at 1.5 hours daily should be enough. I did ten weeks at two hours and scored an 84%. Katz is good for depth but it's dense — use it for your weak domains and don't try to read the whole thing cover to cover or you'll run out of time.

The hearing aid section includes coding and reimbursement questions that surprised me. Make sure you're not just prepping the clinical side — the business and billing knowledge is tested more than the content outline implies.

It's a fixed-format exam, not adaptive. You get 200 questions and four hours. Most people finish with time to spare but I'd recommend marking and reviewing flagged questions rather than rushing — I changed about eight answers on review and six of those changes were correct.

The vestibular section trips up a lot of clinicians who've been in specialized practices. I'd weight your prep based on your clinical gaps, not the official blueprint percentages. If you haven't done much vestibular work recently, give it 25% of your time even if it's only 12% of the exam.

Update for anyone following this thread: I just hit 74% on a practice set last night and honestly I wasn't expecting that. I've been using a mix of resources but what really helped me click on the diagnostic side was working through the free aba audiologic assessment diagnosis questions because they're worded the way the real exam tends to phrase things. Still shaky on vestibular stuff but everything else feels a lot more solid than it did two months ago.

I'm planning to sit in late September. If you're in the same boat just start doing practice questions even if you don't feel ready, that's what finally got me moving.

I felt exactly the same way before I started studying, and honestly the eight content areas had me convinced I'd never be ready. What actually helped me was stopping trying to cover everything equally and just leaning hard into diagnostic audiology first. I found free aba audiologic assessment diagnosis practice questions and drilled them until the patterns clicked. Once that section felt solid the rest of the exam started making more sense because so much of it connects back to assessment fundamentals.

I studied about three months, maybe an hour and a half most weekdays. It wasn't glamorous but it worked. Don't let the content outline psych you out, you probably know more than you think you do from your clinical hours.

Honestly the content domains stressed me out too until I changed my whole approach. I stopped trying to memorize right answers and started obsessing over why the wrong ones were wrong. Like if you miss a cochlear implant candidacy question, don't just flag it and move on -- dig into what made each distractor plausible. I used aba/questions/cochlear implants implantable hearing devices 2 a lot for that because the question sets let you actually think through the reasoning, not just pattern match.

I studied for about four months, roughly an hour a day, and I prioritized diagnostic audiology first since it's the heaviest domain. But honestly the method mattered more than the hours. Once I understood the clinical logic behind wrong answers I started getting stuff right on topics I hadn't even reviewed yet because the reasoning transfers. If you've got four years of clinical experience you already have the instincts -- you just need to trust them and stop second-guessing yourself on exam day.

Honestly the content domains freaked me out too at first, but what actually moved the needle for me was stopping myself from just circling the right answer and moving on. Every time I got a question wrong, I'd force myself to figure out exactly why each distractor was wrong, not just why the keyed answer was right. That shift took more time per question but it meant I wasn't just pattern-matching, I actually understood the underlying reasoning, which matters a lot for the diagnostic audiology stuff where the distractors are genuinely close.

I studied for about four months, roughly an hour a day on weekdays. I didn't treat all eight domains equally, I looked at where my clinical gaps were and leaned into those harder. With four years of experience you probably already have solid intuitions, so trust them, but verify the edge cases. The exam loves to test the exception to the rule you think you know cold.
