Register for an Occupational Licensing Exam

How to apply for a license, pay an application fee, obtain a TCEQ approval, and register to take an exam.

Pre-Approval is Required Before Exam Registration

The TCEQ must pre-approve your license application before you can register for an exam. If approved, you will receive an approval letter (see sample approval letter) in the mail which you must bring with you to your exam. If you don't have a copy or lose your approval letter, you can print a copy of your application status showing "Approved" from searching your name or license number. Approval of an electronic application takes approximately 3-4 weeks if all supporting documentation is provided and there are no deficiencies.

Conditional Approval

A conditional approval is an option if you:

  • are only missing the required core training;
  • have no deficiencies; and
  • intend to take the exam immediately following the required training at a location where the TCEQ, or a TCEQ-designated agent, is proctoring the exams.

When you apply, you must indicate that you intend to apply for a conditional approval and provide proof of the last course registration confirmation and the location, city, and date of the exam you are approved to take.

Note that if you are conditionally approved, you may not register for a licensing exam at a TCEQ Regional Office until you have completed your core training and have contacted the Occupational Licensing Section to request a regular Approval. Once you have an Approved application, you can return to LEXR and register to take an exam in a TCEQ Regional Office.

Conditional Approvals are not accepted at CBT locations.

Retaking an Exam

If an approved applicant fails the exam, they may retake the test a maximum of three times within one year of the application approval date. Retesting is possible as soon as an approved applicant receives a notice of failing the exam in the mail or by CBT, provided the testing center can accommodate the retest. After the fourth unsuccessful test in the one-year period, the applicant will need to submit a new application and fee.
