What does an effective classroom look and sound like? What does it mean to have students engaged in learning? What is high-quality instruction? To answer these questions, the Greece Central School District in New York created a common language around teaching and learning as a way to support student achievement. The district developed a five-year strategic plan to implement a standards-based instructional program, a viable and guaranteed curriculum, and a progress-monitoring system to accelerate student achievement. The strategic plan lays out key goals, strategies, targets, and initiatives that mobilize the district to ensure all students are college- and career-ready. Presented in this article, district leaders in Greece, New York, conduct learning walks through schools to review student data, troubleshoot intervention systems and strategies, and talk with staff, collecting data to build a learner-centered partnership with the principal and school leaders.
