Abstract
WHAT IS ALREADY KNOWN ABOUT THIS TOPIC? International frameworks for evaluating school public health primarily emphasize enhancing student health literacy, whereas domestic research tends to focus on isolated domains, resulting in a fragmented system lacking comprehensive integration. WHAT IS ADDED BY THIS REPORT? Through two rounds of expert consultations, this study developed a three-tier evaluation indicator system for Beijing's primary and secondary school public health system, comprising 59 indicators. The results demonstrated strong expert consensus and high reliability. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE? The indicator system developed in this study demonstrates high levels of expert participation, authority, and coordination, which supports its practical applicability. It provides actionable guidance for strengthening and improving public health systems in primary and secondary schools.
