Encouraging and allowing students to enroll in rigorous courses, such as Advanced Placement courses, is a critical first step in providing more equity in high schools. Leaders must deliberately and intentionally change the conditions that restrict access by rewriting the rules, examining the data, supporting students, teachers, and leaders and establishing accountability based on the idea that all students must have access to the highest academic levels a school offers. The author shares his experience as a superintendent in Stamford, Conn., and Montgomery County (Md.) Public Schools to show how these changes can occur and the differences they can make.
