Seeking Practical Uses of the NYC VAM Data??? « School Finance 101 - 0 views

Jeff Bernstein on 01 Mar 12How, for example, if I was the principal of a given, average sized school in NYC, might I use the VA data on my teachers to council them? to suggest personnel changes? assignment changes, or so on? Would these data, as they are, provide me any useful information about my staff and how to better my school? For this exercise, I've decided to look at the year to year ratings of teachers in a relatively average school. Now, why would I bother looking at the year to year ratings when we know that the multi-year averages are supposed to more accurate - more representative of the teacher's over time contributions? Well, you'll see in the graphs below that those multi-year averages also may not be that useful.
