I was considering grade acceleration until my dd adamantly told me that she wants to stay with her friends. I was looking at info below to give me some gidance on my choice.

You might want to purchase (available at Amazon):

Iowa Acceleration Scale Manual: A Guide for Whole-Grade Acceleration (K-8) 2nd Edition (Paperback)
~ Nicholas Colangelo (Author), Ann, Ph.D. Lupkowski-Shoplik (Author), Jonathan Lipscomb (Author), Leslie, Ph.D. Forstadt (Author), Susan G. Assouline (Editor)

I think it has some checklists and you could go through the checklists and if your child is a good candidate, use your results to present to the school. I have not seen this- but I think that if you are impressed with the content you could even ask them to adopt the standards in the book.

Gook luck!!
