Lamar Institute of Technology is a site for Texas Commission on Environmental Quality (TCEQ) computer-based testing for Occupational Licensing examinations. The TCEQ strives to protect our state's human and natural resources consistent with sustainable economic development. TCEQ’s goal is clean air, clean water and the safe management of waste. The Permitting and Registration Support Division’s Operator Licensing Section oversees 10 occupational licensing programs and maintains approximately 50,000 licenses. Licensing of these individuals ensures minimum competency in occupations directly affecting public health and the environment.

All licensing applicants must be pre-approved by the TCEQ before applicants are eligible to take a CBT. Once approved, the applicant will be eligible to attempt a total of four tests during a one-year approval period (first initial test plus up to three retests). Only eligible tests for that individual will be available for them to take. The CBT application will not allow an individual access to a licensing test if he/she is not eligible to retest. Candidates are allowed to immediately retest after failing the first three of four tests during his/her one year approval period. Sufficient time should be scheduled for the immediate retest if the candidate indicates they want to take advantage of this option.
