A Concrete Strength Testing Technician is an individual who has demonstrated the knowledge and ability to properly perform, record, and report the results of four basic laboratory procedures related to the determination of concrete compressive and flexural strength.
Scope and Knowledge:
This program requires demonstration of the knowledge and hands-on skills covered on the Job Task Analysis (JTA):
JTA for ACI Certification of Concrete Strength Testing Technician
The JTA is a detailed list of specific points of knowledge and skills that may be included in the examinations for this ACI Certification program. ACI urges candidates to use the JTA to prepare for the certification exams.
The program requires a working knowledge of the following ASTM practices and test methods:

- C78/C78M – Flexural Strength of Concrete
Certification Requirements:
ACI will grant certification only to those applicants who meet both of the following requirements:
- A passing grade on the ACI written examination, and
- Successful completion of the ACI performance examination.
The one-hour written examination is closed-book and consists of approximately 40 multiple-choice questions. There are at least eight questions on each of the practices and test methods. To pass the written examination, both of the following conditions must be met:
- At least 60% correct for each of the required practices and test methods, and
- A minimum score of 70% overall.
The performance examination is also closed-book and requires actual demonstration of the required practices and test methods. The examinee is judged on his/her ability to correctly perform all of the required steps for each procedure.
