Beginning with the 1998-99 school year, the board of education shall establish, implement, and enforce a uniform and consistent policy under which a student in any of grades 9 through 12 who fails to maintain a specified minimum grade point average or a specified minimum grade in each course in which the student is enrolled or both is suspended from further participation in any school-sponsored or school-supported athletic or extracurricular activities for a specified period or until a specified minimum grade point average or minimum grade or both are earned by the student. The board of education shall adopt a policy as required by this Section not later than one year after the effective date of this amendatory Act of 1997 and shall concurrently file a copy of that policy with the State Board of Education. After the policy has been in effect for one year, the board of education shall file a report with the State Board of Education setting forth the number and length of suspensions imposed under the policy during the period covered by the report. If the board of education already has a policy that is consistent with the requirements of this Section in effect on the effective date of this amendatory Act of 1997, it shall file a copy of that policy with the State Board of Education within 90 days after the effective date of this amendatory Act and shall file the annual report required under this Section 12 months thereafter.
