Effective September 1, 2017, HB 1508, 85th Leg., R.S. (2017), amended Chapter 53 of the Texas Occupations Code to add Subchapter E relating to notice to applicants to and enrollees in certain educational programs regarding the consequences of a criminal conviction on eligibility for an occupational license.

Pursuant to Chapter 53, Subchapter E, of the Texas Occupations Code, please be advised that Texas Southmost College offers programs that lead to an occupational license as defined under Texas Occupations Code 58.001. Licensing authorities may have guidelines concerning prior criminal convictions that would make an individual ineligible for the issuance of a given license. If you are enrolled in a program that may prepare an individual for an occupational license and/or if you later decide to change to a program that prepares you for an occupational license as defined under Texas Occupations Code 58.001, in accordance with state law, please be advised of the following:

  1. An individual who has been convicted of an offense may be ineligible for issuance of an occupational license upon completion of the educational program;
  2. Each licensing authority that may issue an occupational license to an individual who completes an educational program must establish guidelines that state the reasons a particular crime is considered to relate to a particular license and any other criterion that affects the decisions of the licensing authority.
  3. Local or county licensing authorities may issue additional guidelines related to criminal history. Applicants should contact their respective local or county licensing authority for more details.
  4. A person may request a criminal history evaluation letter regarding personal eligibility for a license issued by a licensing authority under Texas Occupations Code 53.102.

Note that the provisions of Chapter 53 of the Texas Occupations Code relating to the consequences of criminal conviction do not apply to licenses granted by the Supreme Court of Texas, law enforcement officers (Texas Occupations Code Chapter 1701), emergency medical services personnel (Texas Health and Safety Code Chapter 773), or persons licensed by the Texas Medical Board, the Texas State Board of Pharmacy, the State Board of Dental Examiners, or the State Board of Veterinary Medical Examiners that have been convicted of a felony under Chapter 481 or 483 or Section 485.003 of the Texas Health and Safety Code. If you are seeking one of these licenses, please be aware that other law provisions may apply to the consequences of a criminal conviction.

All applicants to and enrollees of Texas Southmost College are encouraged to review all applicable eligibility requirements for the respective occupational license. Questions related to eligibility requirements should be directed to the applicable licensing authority.
