ACI Concrete Strength Testing Certification (CST)

The CST certification is offered to both new technicians and current technicians that expire in 2009. Technicians that are recertifying can elect to attend the day and a half course/exam or take the exam only option (see 'Fees" below).

Established by the American Concrete Institute (ACI) in 1997, the Concrete Strength Testing (CST) certification was developed for certifying experienced laboratory technicians in the following ASTM concrete cylinder test methods:

Course Overview

On day one, the four ASTM standards are reviewed through a combination of classroom and laboratory instruction. On day two, students will complete a written and performance exam demonstrating their proficiency of the test methods.

Exam

The written exam consists of 40 multiple choice questions divided into four sections. Each section covers an individual ASTM Standard. Passing requires a minimum overall score of 70% AND a minimum score of 60% on each individual standard. Students have 60 minutes to complete the written exam.

For the performance exam, students are graded on their ability to correctly perform all required procedures for each of the ASTM standards.

ACI Aggregate Testing Technician - Level I Certification (ATT)

Established by ACI in 2007, the Aggregate Testing Technician (ATT) - Level I Certification was developed to certify experienced laboratory technicians in the following AASHTO aggregate test methods.

Course Overview

On day one, the eight AASHTO standards are reviewed through a combination of classroom and laboratory instruction. On day two, students will complete a written and performance exam demonstrating their proficiency of the test methods.

Exam

The written exam consists of 100 multiple choice questions divided into eight sections. Each section covers an individual AASHTO standard. Passing requires a minimum overall score of 70% AND a minimum score of 60% on each individual standard. Students have two hours to complete the written exam.

For the performance exam, students are graded on their ability to correctly perform required procedures for each of the AASHTO standards.

Certification is required by ASTM C94,"Standard Specification for Ready Mixed Concrete" and ASTM C1077, "Standard Practice for Laboratories Testing Concrete and Concrete Aggregates for Use in Construction".

Certification assures owners, specifiers and other interested parties that testing of strength specimens and aggregate is conducted by qualified laboratory personnel. Recertification is required every five years.

NOTE: Students successfully passing both programs will also receive ACI's Laboratory Testing Technician - Grade I Certification.
