Next month, a million or so North Carolina public-school students between third and twelfth grade will start taking tests. Lots of them. Reading and math tests for the younger kids; biology, Algebra, and English for the older kids.
Their scores will be tabulated and run through some servers at SAS Institute, a private company in Cary. There, software called EVAAS will compare the test score the student earned to one a statistical model predicted the student should get.
