ACI will grant certification to candidates who meet both of the following requirements:
- Passing score on the written examination, AND
- Successful completion of the performance examination.
The one-hour written examination is closed-book and consists of approximately 50 multiple-choice questions.
There are between 6-10 questions on each of the ASTM test methods and practices. To pass the written examination,
BOTH of the following conditions must be met:
- Minimum score of 60% correct for each of the required test methods and practices, AND
- Minimum score of 70% overall.
The performance examination is also closed-book and requires actual demonstration of the required test methods and practices. The examinee is assessed on his/her ability to correctly perform (or describe items verbally, where allowed) all of the required steps for each procedure.
Certification is valid for a period of five years from the date of successfully completing all requirements.
Recertification requires the successful completion of both the written and performance examinations.
