All performance related to military and workplace functions require repeated practice under varied conditions to truly learn and maintain competence in work related tasks and duties.  As has been practiced and studied for over a century, the process of building real workforce experience that is suggested to account for 70% of effective transfer of any knowledge, skill and/or the affective traits needed in a work environment has been a gap in most formal programs of education and training today.  This process involves deliberate drills, assessments, feedback, reflection and the rapid re-design of exercises (experiences) that develops key work-site task-competence at level of difficulty that matches the zone of proximal development of the actor (team or individual).  This is what's called competency-based experiential learning (CBEL). This tutorial will provide an introduction to CBEL and provide the presenters' unique insights into the need, the theory and principles, the components and processes for CBEL.  Materials presented draw upon the presenters’ involvement in previous DoD projects as well as developing the US Army's new Synthetic Training Environment (STE), and in particular, the STE Experiential Learning for Readiness (STEEL-R) research project.  This will be shown in a demonstration of the current STEELR project.
