The Relationship

This study examines the validity of a statewide teacher evaluation system in the Commonwealth of Virginia. Three hundred and thirty-eight teachers from 16 at-risk schools located in eight school districts participated in an evaluation system pilot during the 2011-2012 academic year. Teachers received ratings on six teacher effectiveness process standards and one student academic progress outcome measure. For the outcome measure, student academic progress was measured by student growth percentiles (where available and appropriate) and student achievement goal setting (i.e., student learning objectives). The study examines the internal validity of the system, specifically (1) the relationship between the six teacher effectiveness process standards and the student academic progress outcome measure and (2) the relationship between ratings on outcome measure for teachers with student growth percentile data and without.
