The ACAC certification application process involves three steps:  verification of field experience, the written examination, and certification board review.  There is no required training course for any ACAC certification, although some type of study-review course is recommended.  ACAC does not participate in the development or administration of training courses.

Only those candidates who have successfully undergone verification, examination and review according to the following process can be ACAC-certified:

  1. ACAC certification candidates complete and forward the online application form and required email verifications. 

  2. ACAC certification candidates pass the closed-book examination. If the examination is not successfully passed, a re-examination fee of $100 is required before retaking the examination.  Call (888) 808-8381 to schedule the certification exam after forwarding a complete application file to the ACAC office.

  3. ACAC certification candidates have up to 6 months from the date of application to complete the application process, which includes taking the examination. Applications left incomplete after 6 months will be considered null and void; candidates must submit a new, currently dated application to continue the certification process.

  4. ACAC certification candidates wait for the awarding of the certification. The Certification Board meets every four to six weeks to review the examination results and supporting materials before voting to award the certification.  All votes to award certification must be unanimous.
