You absolutely need to check the “reciprocity” from state to state. You make it sound easy peasy…and it’s not. I know folks who have had to retake the praxis tests in new states, and sometimes even had to take additional college courses. Sometimes…not all the time…but sometimes…they were given provisional or temporary certification.
If a state requires degrees in math to become certified in math…and your daughter doesn’t have this…she will have even more hoops jump through.
She needs a good math program AND a good education program.
