105 ILCS 5/14-7.02c
The Illinois Purchased Care Review Board must accept amended student enrollment data from special education private therapeutic day schools that have specialized contractual agreements with a school district having a population exceeding 500,000 inhabitants in the 2016-2017 and 2017-2018 school years. The amended student enrollment data must be based on actual monthly enrollment days where a student placed by the school district was formally enrolled and began to receive services through the last date he or she was formally exited from the therapeutic day school. All enrolled days must be confined to the official beginning and end dates of the therapeutic day school's official calendar on file with the State Board of Education. In no instance may the amended enrollment be further reduced to account for student absences. A school district having a population of 500,000 or less inhabitants must be billed at the per diem rate approved by the Illinois Purchased Care Review Board based on days enrolled as prescribed in Section 900.330 of Title 89 of the Illinois Administrative Code.
