In the United States, a student's educational attainment is associated with nearly every social outcome we care about: income, employment, life-expectancy, and more. For this reason, it is important to understand how students in Chicago Public Schools (CPS) perform on key milestones of educational attainment, including high school graduation, college enrollment, and college graduation. This annual analysis of CPS students' attainment milestones gives Chicago's education stakeholders a high-level view of how the district performed on these education milestones in 2017, compared to rates from the past decade. This report is framed around the Bachelor's Degree Attainment Index (DAI), an estimate of how many of today's ninth-graders will earn a bachelor's degree within 10 years. The analysis looks at the district's progress on the three milestones that comprise the Bachelor's Degree Attainment Index (Bachelor's DAI)--high school graduation, college enrollment, and four-year college graduation--and also shows the progress for students by race/ethnicity and gender on these milestones. This report also looks at two additional indicators: Freshman OnTrack rates and two-year persistence rates in four-year colleges. Like previous annual reports on the district's educational attainment from the University of Chicago Consortium on School Research (UChicago Consortium) and the To&Through Project, this report is not meant to present new research findings on how policies or practices are impacting students.
