Good Morning Heena, and thanks for contacting CTB. I think that your question may have to be posed to the developers of CHAT, because it may require modifications within the CHAT program to accomplish accessible language. I found a link to the CHAT help desk: www.kayako.com/Live-Chat-Help/Desk-Solution, One possible, but awkward, way to determine Readability Level of CHAT language would be to copy examples into Microsoft Word and then check readability level as part of Spell Check. That still doesn't give you a way to change the language used by CHAT. I hope this helps a little.
