ExploreAbout this exam
The CAET is a certification exam for allied health professionals working in assistive technology and rehabilitation, covering the selection, fitting, and support of prostheses, orthotics, and related devices. Candidates typically come from clinical, technical, and rehabilitation backgrounds and sit the exam to demonstrate a defined body of knowledge to employers, payers, and the public. The exam is multiple choice and spans eight domains: basic sciences; clinical assessment and diagnosis; medical and surgical management; rehabilitation and therapeutic interventions; prosthetics, orthotics, and assistive technology; professional practice, ethics, and patient safety; research, evidence, and quality improvement; and interprofessional and communication skills. Basic sciences and clinical domains carry the most weight, so build those first, then layer on device-specific and practice topics. Preparation works best as a structured cycle: map the domain outline to your own gaps, study from primary texts and clinical guidelines rather than question dumps, and practice applied reasoning across cases.

What you'll study
About CAET preparation
What does the CAET exam actually test?
Applied knowledge across eight domains, from basic sciences and clinical assessment through device management, ethics, evidence, and communication. Expect questions that ask you to reason through a clinical or practice scenario rather than recall a definition in isolation.
How long is the exam, and how many questions are there?
The certifying body sets and periodically revises the question count and time limit. Those figures are published on the official organization's website along with the current content outline. Check there before you plan your pacing strategy.
What score do I need to pass?
Passing standards are set by the certifying body and are not fixed for all time. The official site publishes the current scoring and reporting policy. Do not rely on secondhand numbers from forums or prep vendors.
How hard is it?
Most candidates find it demanding but fair. The difficulty comes from breadth and from scenario questions that combine domains, not from obscure trivia. If you have solid clinical experience and study the outline systematically, the content is learnable.
Can I retake it if I fail?
Retake rules, waiting periods, and any fee differences are set by the certifying body and can change. Confirm the current policy on the official website before you sit the exam, so you know your options in advance.
What order should I study the domains in?
Start with basic sciences and clinical assessment, since later domains assume that foundation. Then move to medical and surgical management and rehabilitation interventions, followed by prosthetics, orthotics, and assistive technology. Finish with ethics, research, and communication, which are lighter but easy points.
Why do candidates fail?
Common causes: studying from question banks instead of source material, skipping basic sciences because it feels like review, ignoring ethics and research domains as low-yield, and never practicing applied case reasoning under time pressure. Breadth failures are more common than depth failures.
How much lead time should I allow?
Most working candidates need a few months of steady study rather than a few weeks of cramming, given the number of domains. Build a schedule around your weakest two domains and protect weekly time for case-based practice.
