Supporters of a proposed charter school serving indigenous students plan to take their application to the state Board of Education, following a second rejection by Oklahoma City Public Schools.

“We are really frustrated that we couldn't come to an agreement with the district ... but it never felt like the district wanted to find that common ground," said Phil Gover, who is leading an effort to launch the Sovereign Community School.

Proposed charter schools can apply to a local school district and appeal a rejection before it can bring its application to the state board.

The Oklahoma City school board denied the Sovereign Community School application earlier this year and rejected its appeal at a board meeting earlier this month.
