The controversial education reforms implemented by Denver Public Schools more than a decade ago positively affected students’ academic outcomes, including increasing their likelihood of graduating, according to a new study released Monday. But the improvements were not felt by everyone, with students of color having mixed results when it came to their math and literacy test scores and graduation chances, the study by the University of Colorado Denver’s Center for Education Policy Analysis found. “What these reforms demonstrate is that they really did improve academic performance for everyone,” said Parker Baxter, director of the center and author of the study.
