--- - |2 Abstract To make evidence‐based treatments deliverable, effective, and scalable in community settings, it is critical to develop a workforce that can deliver evidence‐based treatments as designed with skill. However, the science and practice of clinician training and consultation lag behind other areas of implementation science. In this paper, we present the Longitudinal Education for Advancing Practice (LEAP) model designed to help span this gap. The LEAP model is a mechanistic model of clinician training and consultation that details how training inputs, training and consultation strategies, and mechanisms of learning influence training outcomes. We first describe the LEAP model and then discuss how key implications of the model can be used to develop effective training and consultation strategies. - 'Clinical Psychology: Science and Practice, Volume 25, Issue 3, September 2018.
