Relative to a comparison group with similar demographic and schooling characteristics, students participating in PIC private sector internships had:
- improved attendance in high school
- reduced course failures
- higher participation in SAT
- increased high school graduation rate (5.4 percentage points)
- higher postsecondary enrollment rate (6.1 percentage points).
Importantly, benefits in high school graduation and postsecondary enrollment rate were strong among less advantaged students (those who did not attend exam schools).
