Scope and Knowledge:

The program requires a working knowledge of the following CSA test methods and standard practices:

  •   A23.2–1C—Sampling Plastic Concrete

  •   A23.2–5C—Slump of Concrete

  •   A23.2–6C—Density, Yield, and Cementing Materials Factor of Plastic Concrete

  •   A23.2–3C—Making and Curing Concrete Compression and Flexural Test Specimens

  •   A23.2–17C—Temperature of Freshly Mixed Hydraulic Cement Concrete



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 56 multiple-choice questions. There are eight questions on each of the test methods and standard 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 standard practices; AND
  2.       A minimum score of 70% overall.

The performance examination is also closed-book and requires actual demonstration of five of the required CSA test methods and standard practices plus a verbal description of Standard Practice A23.2–1C (sampling). The examinee is judged on his/her ability to correctly perform or describe all of the required procedures for each test method and standard practice.

Recertification is necessary every five years and requires successful completion of both the written and performance examinations.
