The HECAT (Health Education Curriculum Analysis Tool) provides a framework for analyzing K-12 health education curricula. It contains guidance, analysis tools, and scoring rubrics to assess curricula based on characteristics of effective programs. The HECAT examines curricula's content accuracy, cultural acceptability, feasibility of implementation, and affordability. It also evaluates how well curricula address National Health Education Standards and promote behaviors to prevent priority health issues like substance use, nutrition, injury, and violence. The goal of the HECAT is to help schools select or improve health education curricula that will effectively influence students' health outcomes.
