It sometimes seems as if the terms "high-poverty school" and "low-achieving school" are synonymous, but there are high-performing high-poverty schools all over the country. The reasons for their high performance are many: they have leaders who believe in the capacity of all children to learn to high levels, teachers focus on what kids need to know and they collaborate on how to teach it, and educators and staff work hard to build personal relationships. But they also ensure that all the systems in the school—from discipline and attendance to budget, school improvement plans, and professional development systems—work together to support teaching and learning, thus creating a coherence that eludes many other schools.
