In the case of revocation, the local school board or the State Board , as the chartering entity, shall notify the charter school in writing of the reason why the charter is subject to revocation. The charter school shall submit a written plan to the local school board or the State Board, whichever is applicable, to rectify the problem. The plan shall include a timeline for implementation, which shall not exceed 2 years or the date of the charter's expiration, whichever is earlier. If the local school board or the State Board , as the chartering entity, finds that the charter school has failed to implement the plan of remediation and adhere to the timeline, then the chartering entity shall revoke the charter. Except in situations of an emergency where the health, safety, or education of the charter school's students is at risk, the revocation shall take place at the end of a school year. Nothing in this Section shall be construed to prohibit an implementation timetable that is less than 2 years in duration. No local school board may arbitrarily or capriciously revoke or not renew a charter. Except for extenuating circumstances outlined in this Section, if a local school board revokes or does not renew a charter, it must ensure that all students currently enrolled in the charter school are placed in schools that are higher performing than that charter school, as defined in the State's federal Every Student Succeeds Act accountability plan. In determining whether extenuating circumstances exist, a local school board must detail, by clear and convincing evidence, that factors unrelated to the charter school's accountability designation outweigh the charter school's academic performance.
The State Board may reverse a local board's decision to revoke or not renew a charter if the State Board finds that the charter school or charter school proposal (i) is in compliance with this Article and (ii) is in the best interests of the students it is designed to serve. The State Board may condition the granting of an appeal on the acceptance by the charter school of funding in an amount less than that requested in the proposal submitted to the local school board. The State Board must appoint and utilize a hearing officer for any appeals conducted under this subsection. Final decisions of the State Board are subject to judicial review under the Administrative Review Law.
