Applicants may prepare for this examination by studying contemporary clinical material in each of the five areas outlined above. A suggested reading list has been compiled by the Academy as a reference list to correlate with the examination topics.

Web-based Examination & Administration

The Certified Addiction Specialist Examination is a web-based proctored examination administered by the Academy via the internet. Candidates may schedule a time to take the exam once their application has been reviewed and accepted. Candidates are allowed two and one half hours to complete the examination and the results are available within two weeks from the testing date. The exam is pass/fail based on raw 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.

Examination Fee: $275.00            Re-Testing Fee: $100.00

Once applications are reviewed and accepted, the examination fee will be due. Candidates who do not successfully complete the exam will be contacted and given the opportunity to re-test for the certification.

Steps to Certification:

  • Applicants will be notified within two weeks of the outcome of the exam.
  • Upon successful completion of the exam, the applicant will be awarded Certified Addiction Specialist (CAS) certification.
  • A letter confirming certification, a certificate for framing, and a certificant card will be mailed.
