ABSTRACT
In this chapter, we discuss one of the most influential approaches in evaluating educational effectiveness, the value-added measurement. Having been applied in several countries including Europe and the US, value-added is also becoming popular in some Asian countries, such as China. Despite its popularity, its real value remains disputable. In this chapter, we introduce the underlying principle of value-added measurement, and then use the example of grammar schools in England as an illustration to present the unsettled evidence on educational effectiveness using this approach.
