Okay, I have more information.
-They don't use the MAP test. If we have results they will "add them to his file."
-They won't allow him to take the end of year SSA test for grade 2 (to demonstrate additional mastery to use to support his request to skip grade 1 math). He can only take the SSA test for grade 1 and again, must get a perfect score on it to pass. There's no other above grade testing.
So the process for single subject acceleration will be to have DS take the test. He may get a perfect (maybe 50/50 chance?) score but when he doesn't I need to be prepared to advocate for him to skip anyway.
So my question is, is there any value in having him take some sort of test independently that shows where he's truly at grade level wise for math? And if so what test would that be? We would be using a private psychologist to do the testing.
I still feel if I can show he's 2 years ahead in math it would be a good case to make for skipping 1 grade, but maybe my instincts are off.
TIA for suggestions.
