Convenience Testing for Service Technician Exams

Beginning May 19, 2025, Metro Institute (Metro) will be administering TDA service technician exams. Metro will provide both excellent quality exam opportunities and a convenient schedule for service technicians to test in several locations across the state. Applicants for a license will complete an application and submit to TDA.  After they receive an account number from TDA, they will be able to go to Metro’s website and register for an exam at one of their conveniently located testing locations in Texas

You must be registered with TDA before you can receive payment of any kind for:

• Placing a device into service; 
• Removing an out-of-order tag; or 
• Performing inspections of LPG meters or hopper scales.

TDA may issue a registration to each person who submits an application and subsequently passes a written examination for each class of license desired.

All Service Technicians must be employed by a Licensed Service Company. To apply to be a Service Technician, email your completed RWM-708 application to WeightsMeasures@TexasAgriculture.gov. Once the application is processed, an eligibility letter will be mailed to you with instructions to register for your exams. Once TDA receives a passing exam, the license will be issued. A license is valid for 5 years and at that time the Service Technician will be required to re-test. To request re-testing please email WeightsMeasures@TexasAgriculture.gov.
