Good luck! I hope you get a better idea this time. I am impressed by all the accommodations you are getting in school. Great!!!
Have you talked to him about testing? I used the recommendations from Hoagies. Namely, explained to my dd that they were going to ask her silly and easy questions because the test was designed for kids that were younger than her. It was important that she gave the right answer even if the question was too simple or boring. I also explained that there would be very hard questions since the test was taken by older kids as well (never used the word test though); so it was important for her to give her best guess for those.
I just posted about re-testing my DD. She was also tested at 4 (but closer to 5) and we knew we were not getting a real idea of where she is/was.
When will you get results?
