I have been certified ESL generalist EC-4 for 12 years. I decided to make a change and received a Science Core 4-8 certification. My district says I am not ESL certified for 4-8. I've done some research. Some state that the ESL should extend and cover the new certification. Other state that I would need to take the ESL Supplement 154 exam. Without the ESL certification, I'm losing a $1500 stipend with my district. So I'm trying to figure out what I need to do.
