Something to keep in mind.. as the scores go higher and closer to the ceiling (MAP 2-5 ceiling is 260) , it is harder to show growth. My suggestion , and what we did, was switch to 6plus MAP as a 4th grader. This allows for more questions as its ceiling is 320. We had no success using MAP to get acceleration. We were finally able to get further acceleration after showing WIAT results after a full neuro work-up.

Our district doesn't like outside testing, I had to be very persistent to get them to accept DS's WISC-V (outside) results.
Our district doesn't accept outside testing for gifted services either. We had the neuropsychologist testing due to suspected autism (DX autism level I, anxiety and depression). The WIAT scores for math hit hard ceilings. At that point they gave in a bit but still not sure what to do with him next year as they won't bus him to the junior high for math. Due to his lower (under 130 on WISC) verbal score on the WISC-V, he doesn't qualify for the self contained classrooms where they would place him in the proper math sequence for his ability (His GAI is 140)
