Can you become a teacher with only 3 year degree and of teachers college?

In most places, a 3-year degree from a teachers college is not sufficient to become a fully certified teacher. While a 3-year program might provide some foundational knowledge, most jurisdictions require at least a 4-year bachelor's degree in education or a related field, along with student teaching and passing state-specific licensing exams. The specific requirements vary greatly depending on the country and even the state or province within a country.
