That's more in line with what I understand too. College board looks at your grades and if you are good in school, they are less likely to grant accommodations. Seeing you as more trying to inflate your test scores by claiming a disability.
The College Board does not look at grades.
Here is the information I had to give the College Board when asking for accommodations for my homeschooled son:
--Identifying information
--The name of diagnosed disability
--The requested accommodations (in his case, double time for reading, written language expression, and math calculations; a word processor for essays; small group testing; and writing answers in the test booklet instead of filling in a bubble sheet)
--The documentation from the person who diagnosed the disability
None of this contained anything about his grades or what sort of student he is.
He got all of the accommodations that we requested except for the double time. They gave him time and a half instead.
