Online Examination & Administration

The Certified Addiction Specialist Examination is an online, proctored examination administered by an approved testing center/proctor in your area. Candidates may schedule a time to take the exam once their application has been reviewed and accepted. Candidates are allowed three hours to complete the examination and the results are available within two business days from the testing date. The exam is pass/fail based on raw score. 100 out of 150 is a passing score. The raw score indicates the number of questions that were answered correctly. The minimum score required to pass the CAS exam is established by a committee of CAS subject matter experts, using the Angoff method. The Angoff method is a criterion-referenced methodology in which subject matter experts estimate the passing probability for each exam question. These ratings are averaged to determine the passing score.
The exam must be proctored.
