Poor, Hispanic school focuses on test prep, sees huge gains. But can it be replicated?

Moriah Balingit and T. Rees Shapiro:

A grim picture of academic performance was emerging at Carlin Springs Elementary. Fewer than half of the school’s third-graders had passed the reading and math portions of the Virginia Standards of Learning exam, and numbers for history and science weren’t much better.

Teachers pored over the data, dumbfounded.

“To get information like that back can be like a shock to your system,” said Mary Clare Moller, a literacy teacher at the Arlington, Va., school, reflecting on test results that came in after the 2012-2013 school year. “You’re just thinking, like, ‘But I taught this information. I don’t understand why the kids didn’t get it.’ ”

Moller and other third-grade teachers devised a strategy for the following fall: They led six weeks of daily test preparation lessons, tracked students’ progress with a new computer program and provided extra tutoring for students who seemed at risk of missing the mark.
