This study is the first nationally representative, comprehensive assessment of the school meal programs since the updated nutrition standards for school meals were phased in beginning School Year 2012-2013. The study results are presented in four separate reports summarizing study findings related to (1) foodservice operations, (2) the nutrient content of school meals as offered and served, (3) meal costs and revenues, and (4) student participation, dietary intake and plate waste. A study methodology report that describes the study design, sampling and data collection and a Summary Report that provides a brief overview of the study and key findings from the various reports are also available.
