This report summarizes findings from a study of the psychometric properties of the resilience and youth development module, a key component of the Healthy Kids Survey. The study aims to improve resilience assessment and research so that educators can shape the school environment to promote academic resilience. The Healthy Kids Survey (HKS) is a comprehensive student self-report tool for monitoring the school environment and student health risks.
