Dimensions for VA is a web-based tool available to VA staff that enables detailed searches of published research and research projects. Although physical education teachers generally act as the physical activity champion and promote adherence to whole-school physical activity programs, classroom teachers manage the majority of students'' access to movement throughout the school day. To support the adoption of a whole-school physical activity program, this study developed an instrument that identifies barriers perceived by classroom teachers related to adopting this type of program in their school. A four-step process provided the conceptual framework for this instrument development (literature review, expert review, quantitative evaluation, and validation). The final validation phase ( = 520 teachers) included two individual analyses to separately evaluate respondents from elementary (K-5) and secondary levels (6-12). Each group was randomly split to run exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) of the models. CFA results support models with adequate fit to the data for barriers for elementary, e.g., (SRMR = 0.0726; Bentler CFI = 0.92.79) and secondary (SRMR = 0.0813; Bentler CFI = 0.9374) teachers for whole-school programming. This instrument can be used by school personnel and researchers to understand perceived barriers for classroom teachers to implement a whole-school physical activity program in their context and then follow up to remove or reduce the barriers.
