The agency shall make the procedures available on the agency Internet website. Agency staff must be trained in the procedures and must follow the procedures in conducting the special investigation.
(a-1) During the pendency of a special investigation under this section, the agency is not required to disclose the identity of any witness.

An informal review provided under this section is not a contested case for purposes of Chapter 2001, Government Code.
(i) In conducting a special investigation under § 39.003, the commissioner or the commissioner’s designee may subpoena a current or former school district employee, agent, or official to compel the employee, agent, or official to attend a deposition or produce documents reasonably necessary for the investigation.
(j) If a person fails to comply with a subpoena issued under Subsection (i), the commissioner, acting through the attorney general, may file suit to enforce the subpoena in a district court in this state. On a finding that good cause exists for issuing the subpoena, the court shall order the person to comply with the subpoena and the court may punish a person who fails to obey the court order.
