Certification Requirements

ACI will grant certification only to those applicants who meet both of the following requirements:

  1. A passing grade on the ACI written examination, and
  2. Successful completion of the ACI performance examination.

The two-hour written examination is "open book" and consists of approximately 100 multiple choice questions. There are 8 to 12 questions on each of the Standards. To pass the written examination, both of the following conditions must be met:

The performance examination is closed-book and requires actual demonstration of the required Standards. The examinee is judged on his/her ability to correctly perform or describe all of the required procedures for each standard.
