Hey there-
I was kinda in the same boat as you not too long ago. Recently moving to Texas from NJ was very confusing with the whole certification process. I also hold a BS...after doing some research, I found one place to be the best....Texas Teachers! Some places will only allow you to choose a specific subject area ONLY if you have x amount of credit hours in that certain subject. They actually come across as making you think that is "Texas Policy"....but not the case. Being a Psychology major, that seemed impossible. However, @ Texas Teachers, they let you get certified in "any" area as long as you have a 4 year degree and can pass the test of course. I just finished my training in the spring...lasted 2 months.
Check out the website....I think they have some classes starting for the summer session. Best thing of all...as long as you register with them (even if it's before the classes start), they will sponsor you for the test. That means if you PASS...then start looking for a job. I already have a job with Katy ISD for the fall. They REALLY work with you!!!!
