Brett Macarthur's Response:

This value-added score seems legitimate, and I appreciate seeing it. When I consider how I struggled during my first two years of teaching and compare it to how much I improved in the years after that, I can see why my average value-added scores are what they are. Seeing this score every year would help motivate me to continue to improve my craft.
