My former doctoral student and I put together this video, after conducting a study with teachers in the Houston Independent School District and more specifically four teachers whose contracts were not renewed due in large part to their EVAAS scores in the summer of 2011. This video (which is really a cartoon, although it certainly lacks humor) is about them, but also about what is happening in general in their schools, post the adoption and implementation (at approximately $500,000/year) of the SAS EVAAS value-added system.
