The CONCRETE STRENGTH TESTING TECHNICIAN TRAINING provides an opportunity for new and existing personnel to understand basic laboratory concrete strength-testing procedures, why they are necessary, and to prepare for the CONCRETE STRENGTH TESTING TECHNICIAN exam.
The tentative 08.19.2026 Concrete Strength Testing Technician Training has been cancelled due to lack of interest. There are no Concrete Strength Testing Technician Trainings scheduled for 2026.
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. Once all portions of the exam are passed, the certification is valid through ACI for 5 years. CRMCA does not keep record of certifications or results.
The Concrete Strength Testing Technician TRAINING provides an opportunity for new and existing personnel to understand basic laboratory concrete strength-testing procedures and why they are necessary. The training will encompass the four (4) ASTM practices and test methods contained within the ACI Concrete Strength Testing Technician certification:
- C617/C617M – Capping Cylindrical Concrete Specimens
- C1231/C1231M – Unbonded Caps for Concrete Cylinders
- C39/C39M – Compressive Strength of Cylindrical Concrete Specimens
- C78/C78M – Flexural Strength of Concrete
The one-day course, full of both classroom presentation and hands-on practice, runs from 8:00 AM to 1:00 PM MDT. Registration is required regardless of membership status.

Supplemental Examiners Needed
The ACI certification program provided through the CRMCA is only possible with the help of volunteer Supplemental Examiners. These Supplemental Examiners primarily assist the Examiner of Record for each exam with the administration of the individual performance exam stations for various certifications. Supplemental Examiners are always needed!
In addition to supporting this program and aiding in the advancement of our industry, Supplemental Examiners can earn points for their company which can later be used to cover the costs of future exam registrations. To learn more about these Supplemental Examiner Points (SEPs) and how they can be used, please visit the SEP Program page.
