Ten years ago, I worked as the Director of Assessments for the District of Columbia Public Schools (DCPS). My tenure coincided with Michelle Rhee’s last nine months as Chancellor. I departed shortly after Vincent Gray defeated Adrian Fenty in the September 2010 DC mayoral primary.
My primary task was to design an expansion of that testing program that served the IMPACT teacher evaluation system to include all core subjects and all grade levels. Despite its fame (or infamy), the test score aspect of the IMPACT program affected only 13% of teachers, those teaching either reading or math in grades four through eight. Only those subjects and grade levels included the requisite pre- and post-tests required for teacher “value added” measurements (VAM). Not included were most subjects (e.g., science, social studies, art, music, physical education), grades kindergarten to two, and high school.
Chancellor Rhee wanted many more teachers included. So, I designed a system that would cover more than half the DCPS teacher force, from kindergarten through high school. You haven’t heard about it because it never happened. The newly elected Vincent Gray had promised during his mayoral campaign to reduce the amount of testing; the proposed expansion would have increased it fourfold.
VAM affected teachers’ jobs. A low value-added score could lead to termination; a high score, to promotion and a cash bonus. VAM as it was then structured was obviously, glaringly flawed,[1] as anyone with a strong background in educational testing could have seen. Unfortunately, among the many new central office hires from the elite of ed reform circles, none had such a background.
