Joint Training and Certification Program (JTCP)

About Us

Caltrans, local agencies, and industry have established a joint training and certification program (JTCP) to make the certification process more efficient and to ultimately obtain consistent, reliable, quality testing through joint training. The need to build a proficient workforce to efficiently manage an ever increasing workload is highlighted with the recent passing of SB1. Through the JTCP, testing technicians will receive training, gain proficiency and become certified to sample and test highway construction materials. The JTCP will offer training and certification in hot mix asphalt (HMA), soils and aggregates (S/A), and portland cement concrete (PCC). Through a partnership with CSU Long Beach and San Jose State University, JTCP offers four Modules covering several key test methods identified below. Training and certification through JTCP is required for all technicians to receive or maintain certification in the test methods offered through these modules (some exceptions apply, see JTCP FAQ's).
