This document discusses clinical supervision and assessment of counselor performance. It introduces the Integrated Developmental Model of Supervision (IDM) which has three overriding structures: self and other awareness, motivation, and autonomy. It also describes eight domains of counselor development. The IDM identifies three levels of counselor development with characteristics for motivation, autonomy, and awareness at each level. Performance should be assessed using the TAP 21 competencies and rubrics. Supervision should be tailored to the individual counselor's needs, assessing where they are at developmentally and facilitating goal planning and training recommendations accordingly.
