Thank you Loy58- I was looking at Redbird last night and that might be an option. I had suggested CTY, but it is a lot more expensive and we'd have to convince the school to pay for it. Your point about the multiplication facts is very valid and the amount of time it would take him to compensate for not being fluent in those facts. I'm certainly leaning towards the 3rd grade placement, but all these considerations are really helpful in making our case. A 30-day trial is a great idea too.
geofizz-I'm glad to hear that your acceleration plan for your DS went well and seems like a solid plan. We'd be accelerating 2 years right now, with the option of skipping another one through the compacted program in the coming years. Thank you for suggesting advocating for scheduling now for next year, that will be our next step!
