I am certified to teach Kinder-8 self-contained in Texas. A lot of districts are now requiring elementary teachers to be ESL certified. I am not currently teaching, so there are no district provided professional development classes to help me get ready for the test or whatever it is I need to do to add this certification to my certificate. I'm not even sure where to start. Which certification test(s) do I need to take? Do I have to take some sort of professional development before hand, or do I need to just study for the test and pass it? Thanks!
