Hidden Risk : Consortium on Chicago School Research : 9780999550908 : 099955090X : 11 Oct 2018 : This report builds on prior Consortium research on GPA loss across the transition from eighth to ninth grade. It explores how CPS students' grades declined during the transition to high school in more detail, and considers how both eighth- and ninth-grade grades have changed since the original report was written. It examines GPA declines in arts and PE/health grades, in addition to grades in the core subject areas, and breaks down these declines by race/ethnicity, gender, and eighth-grade achievement, and looks at how these patterns vary across schools. It also explores the relationships between failures in ninth-grade core and non-core courses, credit accumulation, and high school graduation.
