If classrooms teachers play the lead role in establishing relationships that help students do their personal best, principals are leaders in creating good school environments for adults. Westerberg, former principal of award-winning Littleton High School in Colorado, shares six principles that help create positive schoolwide relationships. Drawing on examples from his time as principal, he describes the positive effects of (1) showing students respect; (2) being visible in school; (3) being clearly in control; (4) clarifying your non-negotiables; (5) modeling respect for civility and civil rights; and (6) showing affinity for students.
