A comprehensive provider agency must obtain a criminal history background check on each staff member and applicant to whom an offer of employment is made if the responsibilities of the position include personal contact with an individual receiving services, in order to ensure that individuals do not come in contact with and are not provided services by a staff member who has a conviction for any of the criminal offenses listed in Texas Health and Safety Code, §250.006, or for any criminal offense that the comprehensive provider agency has determined to be a contraindication to employment.
