Compare performance indicators for WA State school districts between 2002 and 2012.
Data are absent for any grade within a district with fewer than 10 students (OSPI doesn't report those figures, due to confidentiality reasons).

A positive residual indicates the district performed better than expected given its poverty level.
A negative residual indicates the district performed worse than expected.

For example, if District A has a residual of 5%, that means that the percent of students in District A who passed the state exam is five percentage points higher than we would predict based the poverty level in District A, and if District B has a residual of -8%, that means that the percent of students in District B who passed the state exam is eight percentage points lower than we would predict based on the poverty level in District B.
