Schools in Los Angeles are now being rated in an entirely new way. Traditionally, they've been rated by the state's API scores, which are still in effect, but now, parents can also assess a public school here with the controversial Value Added system. That assessment looks at how much students have improved in their test scores from one year to the next and purports to reveal whether or not teachers are effective in raising students' achievement. There can be big differences between API scores and Value Added scores. As the LA Times notes today 3rd Street Elementary in Hancock Park has an API score of 938 - out of 1000 -a really high score. But its Value Added score is among the lowest in the district. Incoming Superintendent, John Deasy joins Madeleine to discuss the controversial system.
