The worry in the back of my mind in reading their "wait 20 days" game plan is that I've been around the block too many times and have run into situations where schools put off meeting a child's needs until it is suddenly "too late." We had that situation in 4th grade with my eldest. They had IQ scores and WJ-III scores that were 1.5 yrs old when we came in. They also had 3 month old ITBS scores that were in the 99th percentile for all subjests (except math, which was at the 92nd) and at the 99th for the composite.
They wanted to wait for the MAPS testing to determine her math placement and left her in the regular math class until that could happen. When those scores came in (at the 97th percentile for math and 99th for reading), the accelerated math class was too full and they couldn't move her. She spent that year teaching the other kids math for the most part. Math is not her strong subject, so she really should never be in the place where she is so far beyond the rest of the class that she is serving as a teacher's assistant.
I'd worry that they are delaying until it is too late to make any moves b/c he's missed "too much" of the math for the next grade up, for instance, and they no longer "can" subject accelerate.
I realize that going in guns blazing doesn't always work too well. We've had instances where it hasn't. However, we've also had instances like this year where I was prepared and planning to pull dd9 to homeschool and let them know as much. I told them what things they could fix to make us reconsider and those things happened b/c they were interested in keeping her.
I'd try going in calmly with whatever achievement data you have (even if they already have it as well) and with a list of requests:
I want him placed in the ___ grade math class, etc. I would like a response on these requests by ___ [date]. That way you can at least count on having a yes or no by a certain date and make decisions accordingly.
