COCAS

It is a multiple-choice examination delivered in a single sitting. Expect scenario-based items that ask you to choose the best next step rather than recall a definition. Confirm the current delivery method, whether testing is at a center or proctored remotely, and any accommodations process with the certifying organization before scheduling.

Those figures are set by the certifying body and change over time, so this page does not state them. Check the official organization's website for the current item count and appointment length. When practicing, simulate the real timing once you have it, because pacing is one of the most common reasons strong candidates run short.

Difficulty is best judged by the applied reasoning required, not by trivia. Items typically present a client scenario and ask for the most appropriate clinical action, so memorizing terms is insufficient. Passing standards are criterion-referenced and published by the certifying organization; consult its site for the current threshold rather than relying on secondhand reports.

Retake rules, waiting periods, and any fee for additional attempts are set by the certifying organization and are not stated here. Look up the current retake policy on its official site before you sit the exam, and note whether a waiting period applies, since that affects how you plan a second attempt.

Start with clinical assessment and diagnosis and CBT theory and intervention, the two highest-weighted domains. Build a case conceptualization habit: for each practice vignette, write the presenting problem, maintaining factors, and the indicated intervention before reading answer choices. Add ethics next, then the smaller domains in short review cycles.

These domains punish rule-of-thumb thinking. Ethics items often hinge on the order of steps, such as consulting before disclosing, while cultural items reward integrating the client's context into formulation rather than applying a stereotype. Practice explaining why each distractor is wrong, not just why the key is right.

Enough to collaborate safely, not to prescribe. Focus on major drug classes, common side effects, adherence concerns, and when to refer or consult a prescriber. You should recognize situations requiring medical evaluation and know how to communicate findings to a prescribing colleague. Depth beyond that is unlikely to be tested.

Use them as diagnostics, not as a scoreboard. Take a mixed set early to find weak domains, then study those domains before returning to mixed practice. Review every miss and write one sentence explaining the error. Track accuracy by domain so you can see whether review is actually moving your weakest areas.

Most candidates need several weeks of consistent study given eight domains. Book your appointment only after you have confirmed eligibility requirements and current policies on the official site, and leave buffer time before the test date so a rescheduling policy, if one exists, remains available to you.
