Elizabeth, since your dd has just been recently diagnosed, I'd talk to whoever diagnosed her autism about the school and possible fit. I probably wouldn't consider it at all if it was something she wasn't interested in, but would take her wishes into account - although at the same time, I'd consider whether or not what she thinks about and wants in the school is grounded in what the school really is on a day-to-day basis.
I'd also talk to other parents who's children have attended the school to see if it works in real life the same way it's advertised.
My kids have all attended a similar-type of school and ultimately didn't enjoy it - but in our case the advertised school vs the reality school were different and there were not good supports for developing the skills needed for this type of learning. I also firmly believe that some students are better suited (personality) for this type of school than others.
Best wishes,
