There are two principal licenses, for grades PreK–9 and grades 4–12. The master's degree is required as a subset of the requirements for the Principal's License. The license requires the master's degree plus an additional 15 hours of course work in Educational Administration.
These licenses are intended for those who plan to serve the educational system as leader of a public or private school. Two years of successful teaching under a professional teaching license at the age level for which the principal license is sought is required by the State of Ohio.
Also, the candidate for these licenses must earn a qualifying score of 610 on the Praxis II specialty test (0411). Following a successful entry year experience, the principal license will be added to a valid professional teacher's license.
