An Aggregate Testing Technician 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.

This two-day course involves a full day of classroom instruction. The second day begins with a two-hour written test that is open book followed by the performance test. ACI will grant certification only to those applicants who pass both the ACI written test and successfully complete the ACI performance examination.
