The Marzano High Reliability Schools framework is a data-driven model for school improvement. The framework consists of five hierarchical levels: Safe, Supportive, and Collaborative Culture, Effective Teaching in Every Classroom, Guaranteed and Viable Curriculum, Standards-Referenced Reporting, and Competency-Based Education. Each level builds upon the previous one, with schools working to achieve and maintain these levels progressively. It emphasizes continuous improvement, data-driven decision-making, and research-based practices.
