The Health Education Curriculum Analysis Tool (HECAT) contains process guidance, appraisal tools, and resources for carrying out a clear, complete, and consistent examination of commercially packaged or locally developed school-based health education curricula. Analysis results can help schools select or develop appropriate and effective health education curricula, revise and improve locally developed curricula, strengthen the delivery of health education, and improve the ability of school health educators to influence healthy behaviors and healthy outcomes among school aged youth. CDC has also created a digitized version, HECAT Online, that allows users to interact with a web application to complete health education curriculum analyses. HECAT Online also allows users to develop a scope and sequence for health education.
