(1) Each educational service district superintendent shall cause to be investigated all written and signed complaints, from whatever source, that allege that a certificated education professional within their educational service district is not of good moral character or personal fitness or has committed an act of unprofessional conduct. If the educational service district superintendent themself is the subject of the complaint, the educational service district superintendent will forward the complaint to the superintendent of public instruction for investigation.

(2) If the educational service district superintendent investigates and determines the facts are reliable and further investigation by the superintendent of public instruction is warranted, the educational service district superintendent shall forward the written complaint and the results of their investigation to the superintendent of public instruction.

(3) If the educational service district superintendent, after consultation with the assistant attorney general assigned to their educational service district, determines that the substance of the complaint would not constitute grounds for reprimand, suspension, or revocation if true, then such educational service district superintendent need not investigate the complaint.

(4) If the educational service district superintendent receives a written assurance from the superintendent of public instruction, a district superintendent, or a chief administrative officer of an approved private school that such official is investigating or will investigate the same or a substantially similar complaint, the educational service district superintendent shall be deemed to have caused an investigation in compliance with this section.
