Supplemental Examiner/Proctor Training:
The Supplemental Examiner/Proctor Training is meant to further educate potential, new, interested, existing, or experienced SEs the minimum expectations during ACI certifications and provide further insight and hints to how to be a better SE during sessions, as well as improve training skills outside of the exam room. This training is not mandatory but is STRONGLY encouraged for all potential Supplemental Examiners.

Training – Field Testing Technician Grade 1:
The Field 1 Training provides an opportunity for new and existing personnel to understand basic field concrete testing procedures and why they are necessary. The training will encompass the seven (7) ASTM Standards contained within the ACI Field Concrete Testing Technician certification, which is required for most testing technicians on nearly all project sites. The training is not required prior to registration of a certification session for individuals, though is highly recommended as an introduction and/or refresher on the requirements of the certification. The one-day course full of both in class presentation and hands-on practice is free to CRMCA members.
Concrete Strength Testing Technician:
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 ASTM laboratory procedures related to the determination of concrete compressive and flexural strength.
Aggregate Testing Technician Level 1:
An Aggregate Testing Technician – Level 1 is an individual who has demonstrated the knowledge and ability to properly perform, record, and report the results of basic field and laboratory procedures for aggregates.\
Aggregate Testing Technician Level 2:
An Aggregate Testing Technician – Level 2 is an individual who has demonstrated the knowledge and ability to properly perform, record, and report the results of advanced laboratory procedures for aggregates. ACI states individuals must possess a current certification as an Aggregate Testing Technician – Level 1 to grant certification of Aggregate Testing Technician – Level 2. CRMCA recommends registrants be certified as an Aggregate Testing Technician – Level 1 prior to scheduling this certification.
Laboratory Testing Technician Level 2:
A Concrete Laboratory Testing Technician – Level 2 is an individual who has demonstrated the knowledge and ability to properly perform, record, and report the results of advanced laboratory procedures for aggregates and concrete.
