School Nutrition Environment State Policy Classification System (SNESPCS)

SNESPCS data are currently available from 2003–2012. After 2008, policies are coded every two years.

The SNESPCS 2003 single-year data set and codebook were based on nutrition standards published by the U.S. Dietary Guidelines for Americans and other federal recommendations. In 2008, the SNESPCS data was revised to include recommendations from the Institute of Medicine report, "Nutrition Standards for Foods in Schools: Leading the Way toward Healthier Youth." As a result, the SNESPCS criteria and coding for current combined dataset have changed since the initial publication. Future SNESPCS data sets will be updated according to the most recent nutrition standards that affect the school nutrition environment. The competitive foods, reimbursable school meal, and nutrition education policies are classified according to grade level requirements at the elementary, middle, and high school levels. Grade-level classifications were not made for the remaining topics. C.L.A.S.S. scores reflect the law into effect in the specified year, not law creation date. The citation for source laws coded are available in the SNESPCS Law Citation file. C.L.A.S.S. data are occasionally updated due to changes in policy or coding. If you have any questions or would like to know if there are updates to the C.L.A.S.S. data, please contact nciclass@mail.nih.gov.

Physical Education-Related State Policy Classification System (PERSPCS)

PERSPCS data are currently available from 2003–2012. After 2008, policies are coded every two years. With the exception of recess time, policies for each topic are classified according to grade-level requirements at the elementary, middle, and high school levels. A series of dichotomous tracking variables that might potentially enhance or inhibit implementation or impact the individual policy provisions are also coded for the time requirement, staffing, and assessment-related variables. C.L.A.S.S. scores reflect the law into effect in the specified year, not law creation date. The citation for source laws coded are available in the PERSPCS Law Citation file. C.L.A.S.S. data are occasionally updated due to changes in policy or coding. If you have any questions or would like to know if there are updates to the C.L.A.S.S. data, please contact nciclass@mail.nih.gov.
