Before science teacher Rachel Richards’s Silicon Valley high school eliminated honors classes in her department, teaching the non-honors courses meant you were in for a year of behavioral problems, she recalled.

Now, students from across achievement levels are taught together, and Richards has noticed the teenagers try harder and pay more attention to lessons. “You’re not considered uncool anymore for taking a class seriously,” she said.

Menlo-Atherton High School, where Richards has worked for a decade, is among a number of high schools nationwide that are trying to reduce racial segregation on campuses by eliminating two-tiered systems of honors and regular classes, primarily during freshman year.

The theory goes that starting everyone on equal footing gives more students the confidence and skills needed to enroll in honors and Advanced Placement courses in later years. The changes typically target Black and Latino students, who are underrepresented in advanced courses in most states.
