The board of any district may authorize the employment of attendance officers, who must investigate truancy or nonattendance at school, make complaints, serve notice and process, and attend to the enforcement of all laws and district rules regarding school attendance. When any attendance officer learns of any case of habitual truancy or continued nonattendance of any child required to attend school the officer must immediately notify the person having control of the child to send and keep the child in school. The attendance officer must also refer a habitual truant child as defined in section 260C.007, subdivision 19, and the child's parent or legal guardian to appropriate services and procedures under chapter 260A, if available within the school district. Attendance officers or other designated school officials must ensure that the notice required by section 260A.03 for a child who is a continuing truant is sent. The officer must act under the general supervision of the superintendent.
