At A Glance
- Meal requirements
- Data are independently coded.
- Preferential pricing
- Competitive foods and beverages
- Empirical assessment of state administrative and statutory laws affecting nutrition standards, such as:
- Food service director qualifications
- Body Mass Index (BMI) screening and topics related to advertising/marketing and BMI
- Smart Snacks food and beverage requirements
- Empirical assessment of state administrative and statutory laws affecting physical education (PE) standards, such as:
- PE class time

- Assessment of health-related fitness
- Includes additional coding for factors that may enhance or inhibit implementation of law.
- Laws coded by school level (elementary school, middle school, high school).
- State Profile Tool allows users to compare the relative strength of a state’s laws with recommended standards across multiple policy areas and grade levels at one time.
- Mapping Tool produces downloadable color-coded national maps depicting state comparisons for school nutrition and physical education/activity policy areas.
- Allows users to view relative change in the strength of state laws over time.
- Scoring based on degree of alignment with national nutrition standards (e.g., U.S. Dietary Guidelines for Americans, Institute of Medicine reports, USDA National School Lunch Program, CDC School Health Guidelines).
To collect data about state nutrition environment, physical education, and physical activity laws in the United States and score them in comparison to national standards. C.L.A.S.S. also provides a national map function to compare states on specific policies by grade-level and a state profile function to provide information on all C.L.A.S.S. policy areas across grade-levels in a specific state.
State laws for the 50 states and the District of Columbia.
Began in 2003. Conducted annually 2003-2008, biennially 2008-2012, and yearly thereafter. Most recent year conducted was 2015.
National Cancer Institute, National Institutes of Health, U.S. Department of Health and Human Services
The core of C.L.A.S.S. consists of two policy classification systems, the Physical Education and Recess State Policy Classification System (PERSPCS) and the School Nutrition Environment State Policy Classification System (SNESPCS), to score codified state law on criteria derived from public health research and national standards for physical education and nutrition. The information presented in this profile was previously presented in separate profiles for the PERSPCS and SNESPCS. That information is no longer presented in the Catalogue of Surveillance Systems.
In 2009, the 2003-2006 C.L.A.S.S. SNESPCS was revised to reflect competitive food and beverage recommendations from the 2007 Institute of Medicine (IOM) report Nutrition Standards for Foods in Schools: Leading the Way toward Healthier Youth. As a result, the initial SNESPCS criteria and coding were changed for the 2003-2006 combined dataset.
