ACI 211.1—Selecting Proportions for Concrete*
ASTM C192/C192M—Making and Curing Concrete Test Specimens in the Laboratory
[This standard also requires the knowledge and ability to perform ASTM C143/C143M (Slump), C173/C173M and C231/C213M (Air Content), C138/C138M (Unit Weight), and C1064/C1064M (Temperature).]
ASTM C470/C470M—Molds for Forming Concrete Test Cylinders Vertically*
ASTM C496/C496M—Splitting Tensile Strength of Cylindrical Concrete Specimens*
ASTM C42/C42M—Obtaining and Testing Drilled Cores and Sawed Beams of Concrete*
ASTM C157/C157M—Standard Test Method for Length Change of Hardened Hydraulic-Cement Mortar and Concrete
*Written exam only
ACI will grant certification only to those applicants who meet all of the following requirements:
- Have at least one year (2000 hours) of approved work experience or a combination of work experience and education, AND
- Hold current certification as an ACI Concrete Laboratory Testing Technician—Level 1, and

Course and Test Management
The ACI Certification Program is conducted by a local sponsoring group. This group is the Oklahoma Ready Mix Concrete Association and is responsible for scheduling and conducting all review courses and examination sessions, payment of all bills and establishment and collection of all registration fees. The ACI Certification Department assists the local sponsoring group in setting up the program and manages the daily operation of the program. This includes the publication and distribution of all books and exams, grading, maintenance of certification records and issuance of a certification to successful candidates.
