In school districts having seven or more directors the school board may appoint and remove at pleasure one or more school attendance officers and shall pay them from the public school funds.

2. Each attendance officer has the powers of a deputy sheriff in the performance of his duties. He shall investigate the claims of children for exemptions under section 167.031, and report his findings to the person authorized by that section to grant the exemption sought. He shall refer all cases involving an alleged violation of section 167.031 involving a public school to the superintendent of the public school of the district where the child legally resides and all cases involving an alleged violation of section 167.031 involving a private, parochial, parish or home school to the prosecuting attorney of the county wherein the child legally resides. When reasonable doubt exists as to the age of any such child he may require a properly attested birth certificate or an affidavit stating the child's age, date of birth, physical characteristics and bearing the signature of the child. He may visit and enter any mine, office, factory, workshop, business house, place of amusement, or other place in which children are employed or engaged in any kind of service, or any place or building in which children loiter or idle during school hours; may require a properly attested certificate of the attendance of any child at school; may arrest, without warrant, any truant, or nonattendants or other juvenile disorderly persons, and place them in some school or take them to their homes, or take them to any place of detention provided for neglected children in the county or school district. He shall serve in the cases which he prosecutes without additional fee or compensation. Each attendance officer appointed by a school board shall carry into effect the regulations lawfully prescribed by the board by which he was appointed.

3. In any urban school district, any metropolitan school district and in school districts having seven or more directors and which are located in a first class county having a charter form of government, any duly commissioned city or county police officer shall be ex officio school attendance officers. Any police officer exercising duties of ex officio school attendance officer need not refer any child apprehended pursuant to the provisions of this section to juvenile court or a juvenile officer, but nothing in this subsection shall be construed to limit the police officer’s regular powers and duties as a peace officer.
