High Reliability Schools (HRS)
The Marzano High Reliability Schools framework helps provide a model for continuous improvements. The HRS framework does not replace professional learning communities, the Art and Science of Teaching framework, teacher evaluation and development, sound curriculum (including those aligned with the Common Core State Standards), vocabulary instruction, instruction in critical thinking and reasoning skills, formative assessment, standards-based grading and reporting systems, or student mastery systems.
Instead, this framework shows how best practices work together and provides indicators to empower districts and schools to measure their progress on attaining five increasing levels of reliability:
Using the framework and indicators, districts and schools can drive permanent, positive, and significant impacts on student achievement by synthesizing multiple complex initiatives into one harmonious system.
