Quick Answer
Yes — nearly every US state requires a master's degree (most commonly M.Ed. in Educational Leadership) plus 3-5 years of teaching experience and a state administrator license to be a public-school principal.
The Full Explanation
The typical path is: bachelor's + teacher certification → 3-5 years classroom teaching → M.Ed. in Educational Leadership or Educational Administration → state administrator exam (often SLLA or state equivalent) → administrator/principal license.
Common master's programs include M.Ed. in Educational Leadership, M.Ed. in Educational Administration, or an MBA with an education concentration. Programs are often offered online, with internship or practicum components required.
Most states require passing a School Leaders Licensure Assessment (SLLA, ETS) or a state-developed equivalent. California uses the Administrator Performance Assessment (APA); Texas uses the 268 Principal as Instructional Leader exam.
Private schools often have more flexible requirements — some only require teaching experience, not a master's. Charter school principal requirements vary by state and charter authorizer.
