Independent Assurance Program
IA Program COVID-19 Response:
The IA Program will continue to deliver essential services to new laboratories and new technicians as requested through the IA Service Request system at IA.Service.Request@dot.ca.gov. To reduce exposure risk related to COVID-19, we will provide extensions to those labs and personnel that have current certifications but are expiring. We anticipate these extensions will be offered to laboratories and technicians for approximately one month, though this is subject to change. An IA Service request must still be provided for cases of extension. Caltrans IA personnel will evaluate each service request and work directly with the laboratory and technician for extensions.
Background
Code of Federal Regulations (CFR) Title 23, Section 637 Subpart B requires all sampling and testing to be performed by qualified laboratories and personnel for project-produced materials used in the acceptance decision. The Caltrans Independent Assurance Program ensures that sampling and testing is performed correctly through qualification of laboratories and testers.

IA Service Request
The IA Service Request process has been developed as the request mechanism to provide laboratory accreditations and technician certifications. The IA Service Request is managed through the Caltrans Headquarters Independent Assurance Program within the Division of Engineering Services (DES), Materials Engineering and Testing Services (METS).
Requests for laboratory accreditation and/or tester certification are addressed in the order in which a complete submittal has been received. The general process is as follows:
- Laboratory submits a completed request form and all required documents to the IA Service Request Coordinator at IA.Service.Request@dot.ca.gov. Request forms are available below.
- Cursory review of submitted package is performed for completeness.
- Request is assigned to Independent Assurance (IA) staff.
- Assigned IA will review the submitted package and requests additional information as needed.
- IA staff will schedule and perform laboratory accreditation and/or technician certification.
- The Statewide Independent Assurance Database (SIAD) will be updated with lab accreditation and/or tester certification information.
Questions, concerns, and feedback related to the IA Program or the IA Service Request process may be directed to the IA Service Request email address shown above.

Reference Sample Program (RSP)
2022 RSP Schedule
Topic | Time Frame |
AASHTO T 84 - Determining Specific Gravity and Absorption of Fine Aggregate | January - May |
AASHTO T 209 - Determining Theoretical Maximum Specific Gravity (Gmm) and Density of 3/4 inch Rubberized Hot Mix Asphalt Mixtures | March - August |
CT 540/521 - Determining PCC Strength and Fresh Concrete Properties | September - December |
Reference samples are used to evaluate laboratory equipment and practices, tester competence, and the repeatability of the test methods. RSP provides laboratories an opportunity to compare their performance relative to the entire population of participating laboratories. IA qualification requires laboratories to enroll in the RSP. Laboratories can enroll in RSP and update any changes using the RSP questionnaire.
