Next Tuesday we have a meeting with DD9's principal, AIG specialist, and many others including our psychologist who is pushing for a grade skip to 5th grade. We have the scores, the achievement; we have the backing of the psych; we have a Duke professor arguing for the skip as well. BUT, DD's big sister is in 5th which is one of those big obstacles to grade acceleration. Our counter-argument is that DD9 and DD10 are ALREADY in 5th grade together because of SSA in math (they are in the same math class) plus they are together in AIG math and a foreign language class. If we grade skipped DD9 she would actually be separated from DD10.
I have pulled together research from Davidson and NAGC. Is there any research that can bolter our argument that skipping DD9 can work despite the sibling issue?
