Awesome results, adg! Congratulations to you and your DD. I would certainly take those test results to your school as clear evidence that she needs some accomodations. Don't take "No" for an answer!
As for the DYS program, it's impossible to say from SCAT scores. It's a very short test, and it's not a test that they accept. But if you're up for more testing she may well be a good candidate. If your DD takes the EXPLORE test, you will get a better idea since that is one of the tests that they will look at, and the necessary scores are listed on the website.
