Childhood obesity continues to be a problem of national concern; school-based obesity prevention programs that incorporate nutrition education are among the efforts to address this issue. Implementation of these programs is often conducted through partner agencies like the Supplemental Nutrition Assistance Program Education (SNAP-Ed). As educators within these agencies have limited time and many schools qualify for programming, developing programs that extend reach by partnering with classroom teachers to deliver nutrition education is critical. The purpose of this article is to evaluate the effectiveness of a teacher extender model compared with direct nutrition education from trained staff using the research-tested, evidence-based Shaping Healthy Choices Program. Data collected as part of this evaluation in intervention and control groups included nutrition knowledge, body mass index percentile, and vegetable identification in youth; lesson fidelity observations and feasibility from teachers; and demographics from parents. Overall, unequal within variances did not allow for the statistical power to detect change. Generally, teachers enjoyed the program but found it too time-consuming to implement. While results were unclear, important lessons were learned regarding the implementation of extender programs warranting further research. Overall, this study aligns with others in the literature that indicate time is a major barrier to implementing nutrition education in the classroom. This study underscores the need for policy mandating nutrition education in schools. © 2020 Society for Public Health Education.
