I went to a private school costing 1/3rd of this that had higher test scores. The majority of students were two grade levels ahead in math and reading by middle school iirc.
These seem like middling results, especially considering the socioeconomic situation of these students. $65k/yr is awful ROI.
Paying more for a 3rd grade education than a state college and hearing rumors of it still trying to cut corners with shoddy AI certainly is a choice.
I wish NWEA (which administers MAP Growth) would publish all district-level and school-level score reports. But that would probably drive away most of their customers :(
