This article explores how a one-time training designed to support learning transfer affected 4-H volunteers' comfort levels with the training content and how comfort levels, in turn, affected the volunteers' application of tools and techniques learned during the training. Results of a follow-up survey suggest that the training participants experienced increases in comfort with guiding inquiry-based learning and achieved high levels of application of the tools and techniques presented during the training. The data indicate that providing participants with opportunities during training to experience tools and build skills by practicing techniques helps them more effectively guide learning in the future.
