Synthesis of Information Related to Highway Practices. Topic 55-06. State DOT Certification Programs for Materials Testing Personnel

The Code of Federal Regulations (23 CFR Subpart B) requires that each state department of transportation (DOT) develop a quality assurance program for materials and workmanship that includes the use of qualified sampling and testing personnel. To that end, state DOTs and some groups of state DOTs have developed programs to qualify or certify the personnel performing the testing. The entities that administer the certification programs may be the state DOTs themselves or other entities that have been delegated the authority to administer the certification programs by the state DOTs. The purpose of certification is to indicate that testing personnel possess a thorough understanding of, and competency in, the performance of their duties. This should lead to reliable test results that enable the states to make a valid acceptance decision and comply with the CFR. The purpose is the same for all state DOTs, but the means to qualify testing personnel to perform specific tests, and applicable DOT regulations, varies between the agencies. The objective of this synthesis is to document practices used by state DOTs for carrying out the mandated certification programs for materials testing personnel.
