Start testHow these COTA practice tests match the real exam
The real NBCOT Certified Occupational Therapy Assistant (COTA) Exam has 190 questions and a 240-minute time limit. Question types: Three- and four-option single-response multiple choice plus six-option multi-select items. Each practice test here uses the same question formats, so you get used to how COTA questions are asked before test day.
The tests draw on every COTA content area, weighted like the official outline:
- Collaborate and Gather Information (about 27% of the exam)
- Select and Implement Interventions (about 55% of the exam)
- Uphold Professional Standards and Responsibilities (about 18% of the exam)
Use tutor mode to see the explanation after each answer, or timed mode to practise at real exam pace. Every answer comes with an explanation of why it is right and why the other options are wrong.
