Iowa Admin. Code r. 281-19.19
The school board that established the charter school, in the absence of revoking the charter pursuant to rule 281-19.20(256F), takes affirmative action to renew a charter school contract after the initial four-year contract for a charter school and at the end of each renewal period. The school board shall hold a public hearing on the issue of renewal and submit to the department a copy of the minutes of the public hearing showing that a majority of the school board members voted in favor of renewal of the charter. Any action to renew a charter specifies the number of years, which may only be four years or less, for which the charter was renewed by the school board.
A school board will submit a new application to the department if the board modifies any of the terms of the original charter.
