 TCEQ Occupational Licensing Response to COVID-19

With the onset of COVID-19 (coronavirus) and the Governor’s Proclamation of a state of disaster in Texas, TCEQ is extending the expiration dates of all occupational licenses expiring March through August of 2020 by 30 days. All licenses expiring after August 31, 2020 are expected to comply within the original 3-year renewal cycle. TCEQ is aware that occupational license holders may be having difficulty locating in-person continuing education classes for renewal of their licenses. All license holders are encouraged to seek online training opportunities, when possible.

BPAT license holders whose licenses expire March 2020 through March 2021 are still required to obtain 24 continuing education hours through online courses; however, the TCEQ is temporarily waiving the requirement that eight (8) of the CE hours must be hands-on, practical skills training in order to renew their license. This information and future updates are available at Occupational Licensing Responses to COVID-19 (coronavirus).
