School administrators around the country are getting into trouble for improperly pulling or adding students to their rosters. When it involves fixing data, it's called "scrubbing." And it's rife with temptations: rosier district report cards, added funding and sometimes employee bonuses when performance improves. In Texas, a former superintendent was imprisoned for conspiring to remove low-performing students from classrooms, boosting test averages. Principals in Oklahoma City and St. Louis, Mo., are no longer in their jobs following accusations of attendance manipulation.
