Caring for Our Children: Environmental Health in Early Care and Education (EH) is a collection of 123 nationally recognized health and safety standards that have the greatest impact on environmental health in early care and education settings. These standards and the associated 9 Appendices are a subset of materials available in Caring for Our Children: National Health and Safety Performance Standards; Guidelines for Early Care and Education Programs, 3rd Edition (CFOC3). CFOC3 is a collection of nationally recognized best practice health and safety standards for the early care and education environment. Another important subset of CFOC3 is Stepping Stones, 3rd Edition (SS3), which presents the 138 essential CFOC3 standards that, when put into practice, are most likely to prevent various adverse outcomes in early care and education settings. The SS3 standards included in this collection are designated with an asterisk (*). These noted standards represent the most critical environmental health standards. The purpose of this collection is to serve as a compilation of best practices for environmentally-healthy early care and education programs. In some cases, additional resources may be needed in order to meet the standard. (author abstract)
