OMAHA, Neb. (AP) — The Omaha school district is changing its hiring process for aspiring principals in an effort to build a more robust group of candidates who can tackle a school’s top job.

Instead of a candidate applying directly for the job he or she wants, they will apply to a principal pool. Candidates will then be interviewed and vetted before being considered for a principal position at a specific school.

A committee of district principals, teachers and administrators has drawn up specific job requirements and skills that candidates should be able to demonstrate to prove they’re ready to lead a school.

Omaha Public Schools anticipates that about 10 principals will leave their jobs or retire at the end of this school year.
