I see you are PROMPT certified would you say it is to be used on non verbal kids only? I "know" the answer but fought my district since they wouldn't provide it for one of my boys.
NO WAY! haha And I think PROMPT has recently started to come out with some of their findings for success. There are a lot of people that don't "get" it. And often they are the ones in charge, unfortunately
It took two mediations to get them to resolve it. They will not agree to do it. One of my twins has had 1 sound at the isolation level improvement in three years given "traditional" approaches.
