I've been an ATP for 6 years and finally decided to go for the SMS. My caseload is almost entirely complex rehab so the clinical side feels manageable, but I've heard the exam hits hard on the business and documentation side, which isn't exactly my strong suit. Planning to give myself about 10 weeks and I'm trying to figure out the right split between clinical content and administrative knowledge.
Right now I'm thinking 70% clinical, 30% business and documentation in my study hours. That feels right but I don't know if the exam actually reflects that ratio. Anyone who's taken it recently — does the content distribution match what NRRTS publishes in the candidate guide?
I'm also curious about the equipment knowledge questions. I work mostly with power chairs and tilt-in-space systems so I feel solid there, but I'm less confident on manual ultra-lightweight chairs and pediatric positioning. Should I grind those areas or is it a small enough slice that I can get by with surface-level review?
10 weeks is a comfortable timeline if you're already practicing at a high level. I did 8 weeks at about 1.5 hours per day and passed, but I'd been doing CRT-heavy work for 9 years. Your ATP background gives you a solid foundation.
Your 70/30 split sounds about right based on my experience. I'd maybe shift it to 65/35 in the last two weeks and really hammer the documentation and justification writing. A lot of the business questions are actually about Medicare coverage criteria, which is specific and testable.
Peds positioning was maybe 8–10% of my exam. Enough that you can't ignore it, but not so much that you need to go deep. Know the major positioning principles and the common diagnoses and you should be fine.
The pediatric growth considerations and school-based documentation requirements tripped a few people in my study group.
I passed on my second try after failing by a pretty narrow margin the first time. The thing I underestimated was the outcomes measurement section — functional assessment tools, goal-writing standards. Really worth some dedicated time there.
Just passed mine last month so this is fresh. The business and documentation stuff was definitely where I struggled too, and honestly what got me was doing a deep dive into the AT Act, Medicaid coverage policies, and the letter of medical necessity components. Not just skimming them but actually writing out practice LMNs and checking them against what the coverage criteria require. It felt tedious but the exam had way more questions about justification and coding than I expected.
One thing I didn't expect to matter as much was knowing the difference between what's clinically appropriate versus what's actually fundable, and how to document that gap. If you're strong on the clinical side you might assume the documentation will just follow naturally, but it doesn't always. Give that funding and policy section more time than feels necessary and you'll thank yourself on exam day.
Something that really clicked for me was spending as much time on the wrong answer choices as the right ones. Like, don't just mark C and move on — actually ask yourself why A, B, and D are wrong, because the SMS exam loves to give you options that sound plausible but miss a key compliance angle or mix up the documentation timing. Once I started doing that, I stopped second-guessing myself on the business and billing questions because I understood the logic behind them, not just the answer.
For the 10 weeks you've got, I'd front-load the stuff that feels least familiar — the regs, the documentation standards, the supplier stuff — and leave the clinical pieces for later since you've already got that foundation. It's tempting to start with what you know, but you'll feel way more confident going into test day if the hard stuff isn't still sitting in the back of your mind. And honestly, drilling wrong answers on those business questions will serve you better than reading the same chapter twice.
Six years as an ATP definitely helps with the clinical side — that part felt pretty natural to me too. I gave myself 8 weeks and basically carved out 45 minutes every morning before my first client, and then a longer session on Sunday afternoons. The business and documentation sections were rough at first, but I found drilling category-specific questions helped a lot. I spent a solid week on sms/questions/neurological and medical conditions because I kept second-guessing myself on the medical complexity cases even with my background.
Don't underestimate the billing and justification content. It's not glamorous but it's a real chunk of the exam and it's easy to skim it because it feels like paperwork stuff you already know. I didn't, and I had to scramble. Honestly 10 weeks is plenty if you stay consistent — the hardest part is just protecting that study time when your schedule gets busy.
