Joint Training and Certification Program (JTCP)

COVID-19 Response

In response to the COVID-19 (Coronavirus) pandemic, the JTCP has temporarily suspended delivery of the program through May 22, 2020. Those who were enrolled in a suspended class will be contacted individually by CSU Long Beach staff with options for refunds or transfer into a new section.


Caltrans may grant extensions to existing certifications for technicians who currently hold or have a recently expired certification. Technicians requesting extension should contact Caltrans JTCP personnel at with subject line "Extension Request".

Provisional Certifications

Those new technicians needing certification through these canceled sessions in order to work project direct, will be provided an opportunity for a *Provisional* certification to keep projects moving forward. A *Provisional* certification will require the technician to pass a written and practical examination at their laboratory (or other predetermined location) under the watch of the Caltrans Independent Assurance personnel. The technician must have paid for and be enrolled in a future JTCP session (see CSULB website for available dates and registration). The technician will be required to attend the in-person class at the future date for which they signed up. Technicians requesting *Provisional* certification should fill out the “Technician Training and Evaluation Record TL-0121” and “Employer Affidavit of Testing Proficiency TL-0122” (both available at Caltrans' *Independent Assurance Program site) and submit them to using the subject line of “Provisional Certification Request”.

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)
  • 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).
