This set of questions and answers will help educational leaders and staff discuss and understand key issues related to growth and value-added models of evaluation. Although the responses are universal in their approach, the resource reflects the work of SAS EVAAS organization, which provides value-added measures for the state of Ohio.
This resource provides a clear operational definition for “value-added” models and explores the importance of these models in measuring student growth. It reinforces the distinction between achievement, which is typically measured by a test score, and growth, which is determined by comparing students against themselves and their change in achievement as measured by their performance on state assessments across multiple grades and subjects.
This FAQ sheet also explores how value-added reporting systems are useful, how they are calculated, and how they can predict student performance on tests using test scores from other subjects. It also answers concerns about the reliability and validity of such models as well as strategies for addressing diverse student populations. Readers can also use the FAQ hyperlinks to gain information about interpreting and using value-added measures.
