The Omaha Public Schools board has 45 days to appoint a new District Two representative.
Gray resigned Wednesday from the board. Last November, Gray was elected to a second term as District Two representative.
State law says OPS must give notice, both in writing to the election commissioner or county clerk and to the local newspaper, of the board vacancy. The notice must include information about the vacant board seat and the length of the term.
The vacancy is filled by appointment, and must be done by March ninth.
