Definition of Evidence-Based
Created by the Great Schools Partnership, the GLOSSARY OF EDUCATION REFORM is a comprehensive online resource that describes widely used school-improvement terms, concepts, and strategies for journalists, parents, and community members.
A widely used adjective in education, evidence-based refers to any concept or strategy that is derived from or informed by objective evidence—most commonly, educational research or metrics of school, teacher, and student performance. Among the most common applications are evidence-based decisions, evidence-based school improvement, and evidence-based instruction. The related modifiers data-based, research-based, and scientifically based are also widely used when the evidence in question consists largely or entirely of data, academic research, or scientific findings.
