A national study conducted by Mathematica Policy Research found that students attending KIPP middle schools made gains in reading, math, science, and social studies
equal to 11 to 14 months of additional learning when compared to similar non-KIPP students.60 Similarly, researchers from the University of Pennsylvania found that students selected by lottery to attend Harlem
Success Academy made significant gains in reading and math
equal to 13 to 19 percent higher
test achievement, compared to demographically similar students not selected via lottery.61
An imagination
test, for example, varies depending on the situation, so to unlock a door or to search a cabinet you roll as many dice as you have imagination points and count up the
successes, while another version of the
test has you rolling two dice and seeing if the result is
equal or less than your imagination.
