Scope and Knowledge:
The program requires a working knowledge of field procedures selected from the following ASTM test methods and practices:
- C67—Sampling and Testing Brick and Structural Clay Tile
- C140/C140M—Sampling and Testing Concrete Masonry Units and Related Units
- C780 and C780 Annex—Preconstruction and Construction Evaluation of Mortars for Plain and Reinforced Unit Masonry
- C1019—Sampling and Testing Grout

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.
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 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:
- At least 60% correct for each of the required test methods and practices; AND
- 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.
Recertification is necessary every five years and requires successful completion of both the written and performance examinations.
