Investigation of and response to a complaint shall be as follows:

(1) Upon receipt of a properly filed complaint, the superintendent of public instruction shall send a copy of the complaint to the educational entity, for investigation of the alleged violations.

(2) The educational entity shall investigate the complaint. The responsible official of the educational entity shall respond in writing to the superintendent of public instruction, and include documentation of the investigation, no later than twenty calendar days after the date of receipt by the entity of such complaint.

(3) The response to the superintendent of public instruction shall clearly state either:

(a) That the educational entity denies the allegations contained in the complaint and the basis for such denial; or

(b) Propose reasonable corrective action(s) deemed necessary to correct the violation.

(4) The superintendent of public instruction shall provide the complainant a copy of the entity's response to the complaint.

(5) The superintendent of public instruction will provide the complainant the opportunity to submit additional information, either orally or in writing, about the allegations in the complaint.

(6) Upon review of all relevant information including, if necessary, information obtained through an independent on-site investigation by the superintendent of public instruction, the superintendent of public instruction will make an independent determination as to whether the public agency is in violation of any federal program requirement as authorized under the Elementary and Secondary Education Act as amended by the Every Student Succeeds Act or this chapter.

(7) The superintendent of public instruction shall issue a written decision to the complainant and public agency that addresses each allegation in the complaint including findings of fact, conclusions, and the reasonable corrective measures deemed necessary to correct any violation. The superintendent may provide technical assistance activities or negotiations; and corrective measures necessary to resolve a complaint. All actions shall be instituted, as soon as possible but in no event later than thirty calendar days following the date of the decision, unless otherwise agreed to, or for good cause.

(8) The written decision by the superintendent of public instruction is the final decision in the matter. A complaint is considered resolved when the superintendent has issued a written decision and corrective measures, if warranted, have been completed.

(9) If compliance by a local district or other public agency, educational service district, or other subgrantee is not achieved pursuant to subsection (7) of this section, the superintendent of public instruction may initiate fund withholding, fund recovery, or any other sanction(s) deemed appropriate.
