In 2013, the Washington Student Achievement Council (WSAC) set a 10 year plan for improving the educational attainment of Washington residents. The Roadmap included two educational attainment goals for 2023: (1) All adults in Washington, ages 25-44, will have a high school diploma or equivalent; and (2) At least 70 percent of Washington adults, ages 25-44, will have a postsecondary credential. The Washington state Legislature passed a bill acknowledging these attainment goals during the 2014 session. The primary purpose of this report is to estimate what it will take for the state to reach the postsecondary attainment goal for 2023 and what share of the additional credential holders needed to reach this goal would be expected to come from Washington's community and technical college (CTC) system. The summary section of the report outlines a brief answer to this question; a more detailed description of the background assumptions and analysis to answer this question are provided in the subsequent sections of the report. It was noted during the analysis that the CTC system should also be expected to play a major role in the high school attainment goal, so a similar summary and analysis is provided for the high school attainment goal at the end of this report.
