In the late 1990s, Chicago was a city where only one-half of students graduated high school in four years. Now, students are three times more likely to graduate than not graduate in four years. As more students are making it to the end of eleventh grade to take the ACT — increasing from 53 percent to 85 percent of students — ACT scores are up by almost two points. Additionally, the percentage of students completing AP courses has quadrupled. Twice as many students are earning bachelor's degrees within 10 years of starting high school.

How did this happen?
