Do a need to get an associates degree before becoming teacher?

No, you do not need an associate's degree to become a teacher. To become a teacher in the United States, you need at least a bachelor's degree, and in most states, you'll also need to complete a teacher preparation program and pass a state-specific licensing exam. An associate's degree might be a stepping stone for some people, potentially providing some prerequisite courses, but it's not a requirement for teacher certification.
