In any school district operating on a full year school basis children who will attain age 5 within 30 days after the commencement of a term may attend school upon the commencement of such term and, based upon an assessment of the child's readiness, children who have attended a non-public preschool and continued their education at that school through kindergarten, were taught in kindergarten by an appropriately certified teacher, and will attain age 6 within 4 months after the commencement of a term may attend first grade upon the commencement of such term. The school district may, by resolution of its board, allow for a full year school plan. (Source: P.A. 98-673, eff. 6-30-14.)
