A Masonry Field Testing Technician
is an individual who has demonstrated the knowledge and ability to perform sample preparation and testing of masonry construction-related materials—including materials for brick, structural clay tile, concrete masonry units, prisms, mortars, and grouts—in the field.

Scope and Knowledge:


This program requires demonstration of the knowledge and hands-on skills covered on the Job Task Analysis (JTA):

JTA for ACI Masonry Field Testing Technician Certification

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 field procedures selected from the following ASTM test methods and practices.  You will be required to obtain your own copy of the ASTM Standards listed below:

  • C67/C67M – 18—Sampling and Testing Brick and Structural Clay Tile
  • C140/C140M – 18a—Sampling and Testing Concrete Masonry Units and Related Units
  • C780 – 18 including Annex—Preconstruction and Construction Evaluation of Mortars for Plain and Reinforced Unit Masonry
  • C1019 – 18—Sampling and Testing Grout
  • C1314 – 18—Compressive Strength of Masonry Prisms

Supplemental resources that may aid you in this program are:

  • C109/C109M – 16a—Compressive Strength of Hydraulic Cement Mortars (Using 2-in. or [50-mm] Cube Specimens)
  • C143/C143M – 15a—Slump of Hydraulic-Cement Concrete
  • C1064/C1064M – 17—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 approximately 60 multiple-choice questions. There are between 8 and 12 questions on each of the ASTM test methods and 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 practices; AND
  2. A minimum score of 70% overall.

The performance examination is also closed-book and requires actual demonstration of select field procedures described in ASTM test methods C140/C140M, C780, and C1019. The examinee is judged on his/her ability to correctly perform (or describe, where allowed) required steps for each procedure.

Certification is valid for a period of five years from the date of successfully completing all requirements.

Recertification requires successful completion of both the written and performance examinations.
