Texas Commission on Environmental Quality (TCEQ)
The TCEQ is dedicated to the protection of the environment and human health through the responsible licensing of individuals whose occupations may have an environmental impact. Please visit the TCEQ website for information regarding preparation, requirements, and approvals that you must have before you take an occupational licensing exam.
Texas State University has two locations that provide the TCEQ computer-based testing. You may test at our main campus in San Marcos or at our campus in Round Rock. Please review this website and choose the location that is most convenient for your needs. If you have any questions, please contact the location where you wish to test. For testing at San Marcos, please call TEMC at 512.245.2276. For testing at Round Rock, please call 512.716.4020.
