Does your school do MAP testing twice per year? If so, I'd compare those results. My friend's DD's school did testing 2-3/year. The 2nd and 3rd tests would show a decline. The first test would show an increase. Why? B/c her DD spent the summer reading at her level which was way above the school's grade level so on her first test, she'd test well. After tuning out during the school year, her scores would decline again. Only to go up again AFTER a summer of reading and enrichment.
