Introduction
Creative approaches to obesity prevention have begun in Head Start with a program enhancement called “I Am Moving, I Am Learning” (IM/IL), which is intended to (1) increase the quantity of time children spend in moderate to vigorous physical activity (MVPA) during their daily routine; (2) improve the quality of structured movement activities that are facilitated by teachers and adults; and (3) promote healthy food choices for children each day. In the spring of 2006, Head Start Region III provided 53 Head Start programs with a 2½-day IM/IL training-of-trainers (TOT) event for up to five staff members per program. The trainers and Region III staff encouraged participants to tailor the IM/IL enhancements to their own programs. The Office of Planning, Research, and Evaluation (OPRE) under the Administration for Children and Families (ACF) contracted with Mathematica Policy Research, Inc. (MPR) to conduct an implementation evaluation of the IM/IL enhancements in Region III. The purpose of this study is to examine the extent to which grantees who participated in the spring 2006 regional TOT event are implementing IM/IL enhancements. In spring 2007, MPR conducted a survey of the 53 Head Start programs that had participated in the TOT event.
