Every two years, the Washington State Board of Education (SBE) reports on the health of Washington's educational system. Established in 2013 by the Washington State Legislature, the Indicators of Educational System Health create a common framework upon which to evaluate the overall health of the educational system. The Board has two important responsibilities in this report. First, to report on the state's progress in meeting the goals established for each indicator and second, to recommend appropriate reforms to bolster the outcomes of the indicators not on track to achieving the goals. The report and the supplemental data tables offer plenty of data showing that Washington's educational system is underperforming in two important ways. First, the rate of improvement is not nearly enough to achieve the long-term goals, and second, disparate measures are evident as children enter kindergarten and persist all the way through the post-secondary engagement data. In some cases, gaps between cohorts are getting wider over time, and in some cases, the gaps are noticeably wider than what is observed in other states. The report instills a sense of urgency about addressing the size and scope of achievement and opportunity gaps. The report includes recommendations framed around three overarching questions about Washington's education system that drive the SBE strategic plan: (1) Are young children prepared to learn as they transition into the K-12 system? (2) Do students have access to quality schools and programs? and (3) Do students have the opportunity to develop the skills and knowledge to be prepared for civic engagement, careers, postsecondary education, and lifelong learning?
