Understanding Value Added

I had a new teacher ask me to explain value-added to her. She wanted to know how we could use it to improve test scores.

While value-added is statistically and computationally complex, it really is relatively easy to grasp at a conceptual level.

Test scores are projected for students and then compared to the scores they actually achieve at the end of the school year.

Classroom scores that exceed projected values indicate effective instruction. Conversely, scores that are mostly below projections suggest that the instruction was ineffective. This is very insightful and gives us a framework for developing some differntiated professional development and coaching opportunities.

What are some ways that some other principals are using value added data?
