This paper reports on a project aimed at improving academic achievement at a predominantly Latino elementary school in the metropolitan Los Angeles area. Project activities were guided by a school change model that helped provide a coherent, sustained focus over a period of several years. The model suggests four elements that can be used to produce changes in teaching and learning: goals that are set and shared; indicators that measure success; assistance by capable others; and leadership that supports and pressures. Administration and faculty at the school, aided by UCLA researchers, made substantial improvements in teacher expectations, teaching, school climate, and student achievement.
