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.

Apply for Your License Online Using the Occupational Licensing Electronic Application (OLEA)

To apply for a license, please use OLEA. However, if you must submit a paper check, money order, or ITV (Inter-agency Transfer Voucher - only available for state agencies), you can request a paper application that can be filled out and mailed to the TCEQ with your payment. You can email a request for a paper application to licenses@tceq.texas.gov and include the following statement in the body of the email: "Please email me an application for [license type] so I may submit my payment via paper check, money order or ITV." Don't forget to include the license type in your request. Paper applications will be processed in approximately 6-8 weeks, if they are complete with no deficiencies.

Testing Methodslicensing exams via cbt

There are two methods to take an exam: Computer-Based (CBT) at one of several testing centers or Paper-Based at one of the TCEQ Regional offices. Preapproval of your application is required for both testing methods before you may register to take an exam.

Computer-Based Testing (CBT)

We strongly encourage you to take advantage of the CBT opportunities. If the CBT exam you need is not offered, or you are not able to take computer-based examinations, the paper-based exams are offered in the regional offices. Visit the Computer-Based Testing webpage for more information.

Some of the benefits are:

  • Convenience (more location, more frequently offered)!
  • Offered 5-7 days a week, depending on location!
  • Immediate exam score!
  • Immediate exam analysis feedback!
  • Faster receipt of licenses!
  • Immediate retesting available!

Many Computer-Based Testing exams are available in the following exam locations:
