I'm a rehabilitation specialist at a post-acute TBI program and my supervisor wants me to get the CBIS within the next year. I've been working in brain injury rehab for 3 years but I'm not sure how much of what I know from clinical work translates directly to what's on the exam. The content outline covers medical aspects, cognitive and behavioral issues, community integration, and ethics and professional issues.
The medical section is where I feel weakest. I do the functional rehab side but I'm not a nurse, and the neuroanatomy and pathophysiology questions are outside my daily practice. I've been spending most of my prep time there — about 45 minutes a day on medical content and another 30 on practice questions. Three weeks in I'm averaging around 68% on practice tests, which feels low with 8 weeks still to go.
The ethics section is also making me nervous because it covers both general professional ethics and brain injury-specific scenarios like surrogate decision-making, capacity assessment, and community reintegration barriers. Those topics don't come up much in my actual job so I need to give them real attention. Has anyone taken the exam recently and noticed big content shifts from older prep materials?
I took it about 14 months ago. The prep materials I used were from 2022 and were still accurate for core content, though the community integration section had gotten more emphasis on supported employment and independent living outcomes than older materials reflected. Medical and behavioral content hasn't shifted much.
68% at 3 weeks out with 8 weeks to go is totally fine — don't panic. I was in the same spot and ended up at 79% on the real exam. The neuroanatomy piece genuinely does require deliberate memorization if you don't use it daily. Flashcards for major structures and their functions got me from 65% to 80% on that domain alone.
Three years of TBI rehab experience will carry you through the behavioral and community sections even if you feel shaky going in. The exam rewards clinical reasoning and your real-world experience fills in a lot of gaps you'd miss studying cold. Concentrate your remaining time on the medical weaknesses and you'll be fine.
The ethics and professional issues section gets underestimated a lot. A lot of it ties to BIAA standards and principles of community-based rehabilitation. If you haven't read the BIAA's professional standards document, do that before your exam date — some questions reference it pretty directly.
