Certification Requirements:

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

2. Successful completion of the ACI performance examination.

The one-and-a-half-hour written examination is open-book and consists of approximately 70 multiple-choice questions. There are between 8 and 12 questions on each of the ASTM test methods and practices. To pass the written examination, BOTH of the following conditions must be met:

1. At least 60% correct for each of the required test methods and practices, AND
2. A minimum score of 70% overall.

The performance examination is closed-book and requires actual demonstration of select field procedures described in ASTM test methods C140/C140M, C780, C1019, and C1552. The examinee is judged on his/her ability to correctly perform (or describe, where allowed) the required steps for each procedure.

Certification is valid for five years from the date of completing all requirements. 

Recertification requires successful completion of both the written and performance examinations.
