OMAHA, Neb. (AP) — Parents are voicing concern about a grant that would bring new federal money to Wakonda Elementary in Omaha, but would require that half the school’s teachers and its principal to be replaced.

Omaha Public Schools’ administrators are applying for the federal school improvement grant that would give the school, which is listed as one of the state’s lowest-achieving, about $1 million over three years for student improvement.

Superintendent Mark Evans told parents at a meeting Thursday that the principal has decided to retire, and that a replacement would be hired if the is approved. Teachers would also have to reapply for their jobs, but only half of them would be rehired.

Many parents are worried their children will have trouble adjusting to new faces and teaching styles.
