Confusion often arises around this question because there are 4 main paths to completing a teacher prep program:
As part of your bachelor’s in education.
As post-graduate, traditional certification; some programs in this format can lead to a master’s degree, others are “certification only”.
As post-graduate, alternative certification. This route may allow you to begin teaching with temporary certification while you finish your teacher prep but is most likely to be available in teacher shortage areas.
As part of a post-graduate residency model. This model imitates the medical school model, painting a full academic year of apprenticeship with a master’s program. You may be required to stay at the same school for several years following completion of the program. This route is also more likely to be available in teacher shortage areas.
