We have also struggled with this. DD13 has been 2-4 years ahead in math and English but has always had to take her grade level tests. I have sat with her for a bit of practice prior to the test this year as it will depend on whether she gets gifted high school placement. Its been awhile since some of the 7th grade math concepts etc. It was amazing to see her try and make the problems harder than they were. On top of that the gifted high school coordinator will not accept the SAT scores in place of the grade level scores if her scores do not make the gifted range.....
