You definitely need at least a Bachelor's degree. And you need to pass the MTELs.

I wrote preliminary but it's called provisional. If you completed an educator preparation program during your Bachelor program, you can skip to the initial licensure. Otherwise, you start with the provisional license and have to complete the educator preparation program on your own. Without it, you cannot advance to the initial licensure. The provisional lasts for only 5 years and cannot be extended.
