The "Pathways to Teaching: Teacher Diversity, Testing, Certification, and Employment in Washington State" study examined the state's shortage of teachers of color. The study investigated six steps in the teacher preparation and career pathway at which teacher candidates and teachers are likely to drop out or leave the profession: three teacher preparation tests, certification, employment, and retention. Among all teacher candidates who took at least one of these steps during 2010-19, Hispanic candidates and non-Hispanic candidates of color were less likely than White candidates to complete each step, took longer to complete each step, and were less likely to become a certificated educator in a Washington K-12 public school. The descriptive findings suggest that education policymakers consider revising policies and programs to increase the number of teachers of color. This document presents the following two appendixes that accompany the study: (1) Methodology; and (2) Supporting analyses. [For the full report, see ED613183. For the Study Snapshot, see ED613184.]
