While some entry-level roles might not explicitly require prior education experience, most teaching and administrative positions within K12 schools will require a relevant degree (like a Bachelor's or Master's in Education) and often prior experience, even if it's through student teaching or internships. The specific requirements vary significantly depending on the role (teacher, administrator, bus driver, cafeteria worker, etc.) and the specific K12 school or district.
In short: While you might find *some* positions without prior education experience, it significantly limits your options and increases competition for those limited roles. A relevant background in education is almost always a substantial asset and often a requirement.
