110 ILCS 805/3B-3
Every Board shall provide by rule or contract for a procedure to evaluate the performance and qualifications of non-tenure faculty members. If the implementation of such procedure results in a decision to dismiss a non-tenure faculty member for the ensuing school year or term, the Board shall give notice thereof to the faculty member not later than 60 days before the end of the school year or term. The specific reasons for the dismissal shall be confidential but shall be issued to the teacher upon request. If the Board fails to give such notice, within the time period, the faculty member shall be deemed reemployed for the ensuing school year. If the Board fails to give such notice within the time provided during the third year, or during the fourth year in the case of a one year extension, the faculty member shall enter upon tenure during the ensuing school year or term.
