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 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 AASHTO/ASTM standards:

ASTM C617/617M – Standard Practice for Capping Cylindrical Concrete Specimens
ASTM C1231/1231M – Standard Practice for Use of Unbonded Caps in Determination of Compressive
Strength of Hardened Concrete Cylinders
ASTM C39/39M – Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens
ASTM C78/78M – Standard Test Method for Flexural Strength of Concrete (Using Simple Beam with
Third-Point Loading)

 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 one-hour written examination is closed-book and consists of approximately 40 multiple-choice questions.
