Disaggregated analysis of 2012–14 CPS immediate enrollees by GPA, ACT score, race/ethnicity, and gender (Figure 5; 25,527 students). The report states Black young men's four-year rate was 13% with six-year rates "around 20 percentage points higher" (31% per the Implications section). No effect size is printed.

"The four-year completion rates for Black young men (13%), Black young women (20%), and Latino young men (23%) were lower than the rates for their peers. The six-year completion rates for these groups were around 20 percentage points higher."
