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: 
1. At least 60% correct for each of the required standards, and
2. A minimum score of 70% overall.

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. 

Recertification is necessary every five years, and requires successful completion of both the written and performance examinations.
