Teacher Collective Bargaining

Abstract

In 2010, Strunk and Reardon introduced a potentially transformative method for analyzing teacher collective bargaining agreements (CBAs). We extend Strunk and Reardon’s work by assessing whether the Partial Independence Item Response (PIIR) approach can be applied to subsets of provisions from CBAs, data that may be more feasible for researchers to collect. Utilizing a new data set derived from all provisions in all active CBAs in Washington state, we find that estimates calculated from a subset of high-profile provisions are moderately highly correlated with estimates calculated from the full range of provisions, as are estimates calculated from several categories of provisions. This suggests that researchers can still draw important conclusions by applying the PIIR method to readily available data on teacher CBAs.
