One of the basic requirements to become a kindergarten teacher is earning a bachelor's degree. A program that focuses on the needs and development of young learners, such as an early childhood education degree, is typical preparation for this career. For teachers in public schools, a state-issued teaching certificate is also necessary. Many programs also require completion of a student teaching internship before a teacher can be licensed. The common steps to becoming a kindergarten teacher are as follows:
Earn a bachelor's degree in early childhood education or a closely related subject.
Complete a student teaching internship in a kindergarten classroom as part of a state-approved teacher preparaton program.
Take your state's required tests for prospective kindergarten teachers.
Apply for a teaching license.
Begin applying for open kindergarten teaching jobs.
Prospective teachers who already have a bachelor's degree in a subject other than education may be able to qualify for teacher certification by completing a master's degree in education that focuses on the needs of young learners and is designed to lead to initial certification. Teachers of kindergarten in private schools must usually have at least a bachelor's degree, but a state teaching license is not always a requirement in private schools.
