If certification expires the specialist may not perform any Level 1A responsibilities on a TxDOT project. If Level 1A certification expires and the Specialist is Level 2 certified the Level 2 certification will also be inactive.

Level 1A Exempt

All Level 1A Specialists that hold certification for nine (9) consecutive years will be classified as Level 1A Exempt. As a Level 1A Exempt Specialist re-certification is no longer required. The Specialist is, however, required to participate in the federally mandated annual proficiency program. NOTE: In order to become exempt individuals must call the Hot Mix Asphalt Center to request re-classification as Exempt.

Training Class

The Level 1A Training classes will be three-days in length and focus on providing a basic understanding and knowledge of the TxDOT Test Procedures and Specifications. These classes are not pre-requisites to any certification class and participants will not earn certification.

Federally Mandated Annual Proficiency

The Texas Department of Transportation requires all Level 1A Specialist to participate in an Annual Proficiency Program. Participation in this program is MANDATORY. Failure to participate will result in certification revocation.
