New growth model highlights students' MCAS gains

For the first time yesterday, the Massachusetts Department of Elementary and Secondary Education reported student and school MCAS progress using a "growth model." Instead of comparing how different groups of students perform on the same test (e.g., 2009 4th graders vs. 2008 4th graders), the growth model follows the same students' progress from one year to the next. Today's Boston Globe highlights the O'Donnell Elementary School in East Boston showing tremendous student gains under the new model.
