The important role that education plays in shaping young people's lives has been well-documented. Students who complete higher levels of education are more likely to earn higher salaries, have greater life expectancy, and report higher levels of life satisfaction. Compared to a decade ago, thousands more Chicago Public Schools (CPS) students reach key milestones of educational attainment each year, including high school graduation, college enrollment, and college graduation. This annual analysis of CPS students' educational attainment provides a high-level update of district trends through 2018, shows a comparison of attainment by race/ ethnicity and gender, and projects the bachelor's degree attainment rate for students who completed ninth grade in 2018.[For the 2017 Research Brief, see ED593615.]
