Basic page Study Series: School Meal Program Operations

We have studied school meal program operations for a long time. You can access published reports that go back to school year 1988-89. Each study in this series focuses on topics that are important to program operations at the time. Sometimes the studies also collect information about other child nutrition programs, like the Child and Adult Care Food Program and Summer Food Service Program.

Resource | Research and Data | Assessing/Improving Operations School Meals Initiative Implementation Study: Second Year Report

The National School Lunch Program and the School Breakfast Program are central parts of a national policy designed to safeguard and promote the nutritional well-being of the Nation’s children. The programs are administered by FNA, operating through state agencies that have agreements with the local school systems in their states. Despite the progress that has been achieved over the years in enhancing the quality of school meals, results of research conducted in the early 1990s indicated that school meals, on balance, were failing to meet certain key nutritional goals.
