Purpose
The GSHS is part of a global surveillance system designed to provide accurate data to periodically monitor the prevalence of important health risk behaviors and protective factors among students 13 to 15 years of age.

The GSHS is a relatively low-cost survey which uses a self-administered questionnaire to obtain data from a representative sample of students. Countries implementing the GSHS receive technical assistance from PAHO/WHO and the CDC.
Countries can add questions to the “core” GSHS questionnaire.
