Iowa Admin. Code r. 501-10.210
The minimum qualifications for certification of a general instructor include the following: a regular, nonprobationary Iowa certified sworn peace officer (active, inactive, or retired in good standing) with documented experience in the subject area to be instructed and endorsement by the chief, sheriff, or agency administrator of a law enforcement agency or other agency approved by the council as to the person's qualifications to instruct. Good standing is determined by the endorser and by the academy. A person who has been dismissed for good cause from previous employment, who left during an internal affairs investigation that would have resulted in dismissal for good cause, or who is currently involved in the decertification process shall not be considered in good standing.
