The To&Through Project provides data on the milestones that research shows matter most for students’ high school and college success in one online hub for education stakeholders. The To&Through Online Tool links Chicago public high schools to post-secondary outcomes, providing the full picture of students’ educational progress, from the middle grades through college graduation. District and school leaders, school partners, families, and policymakers can interrogate district and school level data. The Online Tool can be used to examine patterns of educational attainment among different student subgroups, see how many students from individual high schools have reached a particular milestone along the path to and through college, and see which colleges and universities Chicago Public Schools students are choosing, as well as the institutional graduation rates of those schools.
