This document on consultation is one of seven staff development programs which target performance skills of school counselors. The staff development programs are one component of a comprehensive student-needs-based guidance system developed by the Pioneer Cooperative Educational Service Agency Guidance Project. The staff development programs are designed to be used by students who aspire to become school counselors, by entry level counselors who are seeking to demonstrate their skill for certification purposes, and by experienced counselors who wish to enhance their skills. The emphasis of each program is on performance. A format has been developed which uses behavioral indicators as the focus for activities. A basic knowledge of the area of functioning is assumed. Where this prerequisite knowledge is not present, selected readings and references are provided. This document discusses preassessment, the consulting process, consulting functions, and postassessment. (Author)
