Editor's note: VAM is the use of students' test scores to assess the effectiveness of teachers. It is a methodology promoted by U.S. Secretary of Education Arne Duncan, who is also a proponent of the Common Core...the standards on which the new Smarter Balanced and PARCC standardized tests will be based...which in turn are the tests that VAM would use for teacher assessment.
