Table 2: Proficiency questions results (i.e, Self-Rated Skills). Note: Self-rated proficiency questions showed great improvement following the day’s training, with the largest positive percent change occurring in the “skilled category” for most questions. The two questions having the largest shift in response from “Not Aware” to other increased knowledge categories were “Format of Liberating Structures” (Question 1), total of 88.57%, and “Application of Liberating Structures” (Question 2), total of 85.71%.
