All (Level 1A Plant Production Specialists, AGG101 Aggregate Specialist, SB101 Properties Specialist and SB 201 Strength Specialists) are required to participate in the Federal Highway Administration’s Annual Proficiency Program. Participation in this proficiency testing program is mandatory in order to meet the Federal Highway Administration’s requirements listed in 23CFR637, “Quality Assurance Procedures for Construction.”
Some of the benefits of proficiency testing are: reducing variation in testing, helping identify equipment and procedural problems and reducing the number of disputes that may arise because of testing variation between two or more laboratories. It is important to note that proficiency testing is not a competition. Results are compared to statewide averages, not to known values. All ratings are indicators of how representative a particular laboratory is of the average laboratory in the state.
In order to participate in the Annual Proficiency Program, Specialist must log into the HMAC’s website at www.txhmac.org to verify employment information.
TxDOT sends all proficiency samples. Specialists are allowed approximately one month to independently perform the tests and submit results. After performing tests on proficiency samples, results must be entered on the HMAC’s website for analysis by a deadline set forth by TxDOT.
Once ratings are posted, each technician must login and view ratings. Any rating of two or below must be responded to with a low rating response by the given deadline determined by TxDOT.
If a Specialists does not participate in all aspects of the proficiency program their certification will become inactive. These Specialists will not be allowed to perform QC/QA testing on any TxDOT project until they successfully complete the course again at the HMAC.
If (Level 1A/SB201) certification becomes inactive due to lack of participation in the proficiency program, the (Level 2/SB202) certification will also become inactive.
