Cricket3, I also believe that Common Core will make it more difficult for students to accelerate in our elementary schools as well. The plan is to make GT math more rigorous by including more higher level math beyond the current one year acceleration plus enrichment. I am glad that DS was just ahead of that wave and is allowed to study algebra as a 5th grader this year. Interestingly, the Common Core inspired changes to the GT math curriculum would have benefited his less mathy twin sister, who refused acceleration, but completed Aleks 6th grade math the summer after 3rd grade when I had DS complete Aleks pre-algebra to decide on the advisability of another acceleration.
