Hopefully, this will lead to it being removed from other state’s evaluation processes.
Today, teachers in Houston won a major court victory against the discredited teacher evaluation method called VAM, or “value-added measurement.” The court battle was led by the AFT and the Houston Federation of Teachers.
VAM was originally developed by an agricultural statistician, William Sanders, who believed that the rise or fall of student test scores can be attributed to the students’ teachers. This theory was incorporated into the Race to the Top program, which led many states to adopt it, despite the fact that it had never been proven to Wotan in a real-world situation. Seventy percent of teachers do not teach tested subjects, which led to bizarre strategies of evaluating teachers by scores of students they never taught in subjects they never taught.
Here is the press release from the AFT about the decision:
