Welcome to Kindergarten. crazy I had to laugh reading your post because I felt the same way when DD8 started. When DD6 started Kindergarten I took a totally different approach. Instead of dropping hints and waiting for the school to do something, I had her privately assessed. I met with the principal in the spring before she started and asked for subject acceleration backed up by the test results. This allowed her to have play time with her age mates while learning more challenging and interesting concepts with children in the next grade up.

I've found like the insurance company, schools are more likely to act in response to a written letter rather than e-mail or conversation. Good luck!
