Just a note -- ELPA21's popularity shrunk a lot, as they used to have 21 participating states and not have 7ish from my understanding. They probably won't state it that way, but WIDA has become a lot more dominant in the space. According to the web, they have 11 states — Arkansas, Florida, Iowa, Kansas, Louisiana, Nebraska, Ohio, Oregon, South Carolina, Washington, and West Virginia ==> BUT for example, Kansas switched to KELPA... so I can check on who is left if you are interested... I have a list somewhere!

Cool, thanks Kaitlyn!
