Except for a school district organized under Article 34 of this Code, a truant officer or, in a school district that does not have a truant officer, the regional superintendent of schools or his or her designee, after giving the notice provided in Section 26-7, shall determine whether the notice has been complied with. If 3 notices have been given and the notices have not been complied with, and if the persons having custody or control have knowingly and willfully permitted the truant behavior to continue, the regional superintendent of schools, or his or her designee, of the school district where the child resides shall conduct a truancy hearing. If the regional superintendent determines as a result of the hearing that the child is truant, the regional superintendent shall, if age appropriate at the discretion of the regional superintendent, require the student to complete 20 to 40 hours of community service over a period of 90 days. If the truancy persists, the regional superintendent shall (i) make complaint against the persons having custody or control to the state‘s attorney or in the circuit court in the county where such person resides for failure to comply with the provisions of this Article or (ii) conduct truancy mediation and encourage the student to enroll in a graduation incentives program under Section 26-16 of this Code. If, however, after giving the notice provided in Section 26-7 the truant behavior has continued, and the child is beyond the control of the parents, guardians or custodians, a truancy petition shall be filed under the provisions of Article III of the Juvenile Court Act of 1987.
