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

Research conducted in the early 1990s indicated that school meals, on balance, were failing to meet certain key nutritional goals. In light of these findings, the USDA launched a far-reaching reform of the school meals programs, a reform aimed at upgrading the nutritional content of school meals. Several elements of this reform are collectively referred to as the School Meals Initiative for Healthy Children (SMI). The status of this initiative, together with an examination of selected operational issues of these programs, are the principal subjects of this report.
