UChicago Consortium study finds high-school GPAs outweigh ACTs for college readiness

[roethlisburger]

That 20% of students with HS GPA < 1.5 graduate from college suggests that there is a non trivial number of “late bloomers”, and that one’s HS academic performance does not necessarily mean that one will continue to do similarly later.

One explanation is the institutions that will admit students with sub 1.5 GPAs have easy grading standards and try their best to graduate anyone who demonstrates at least minimal competency.
