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.
Step 1. Register for your TCEQ exam. Visit the TCEQ website to register or call 512-239-1000 for assistance.
To request your appointment, select your site.
We'll reply with an email either confirming your choice, or offering some alternatives. When an appointment has been set, we'll send you a link to pay our test administration fee.
Pay your Texas State administration fee. Texas State University requires an administration fee based on the time limit of the exam.
See "Available Exams and Time Limits" below.
Up to 2 hours = $40 Up to 3 hours = $50 Up to 4 hours = $60 Up to 6 hours = $80
Bring the printed receipt as proof you paid.
Step 4. On the test day please bring your printed approval form from TCEQ, your administration fee receipt, your social security number, and approved forms of identification. You will not be allowed to test unless you have all the required documentation and identification with you.
Note: TEMC cannot provide refunds for any fees or payments beyond five business days from the date of payment. Your payment receipt is valid for 90 days from the date of purchase. It is essential to submit an appointment request within this timeframe to be eligible for testing.
TCEQ exams that are 4 hours or less in duration may be retaken on the same day if time and space permits. If retesting is available, you will be allowed a short break, without study, and time to make the additional fee payment before the retest begins.
