Before applying for a teacher’s certificate, you must obtain a bachelor’s degree from an accredited college or teaching program. Earning a bachelor’s degree is typically a three-to-four-year program.
Then you will most likely have to complete a student teaching experience followed by taking your state examinations to prove you’re qualified, adding a few more years.
After these steps, you can apply for your teaching certificate, state requirements will vary, but this is the general process.
