This report presents the highlights of a year's experience with the advisory approach to the in-service education of elementary school teachers. The term "advisory" is defined as in-service assistance to teachers that is provided only at their request, in terms of their own goals, and "in situ" rather than in formal courses; it is designed in such a way that teachers become self-reliant and independent. The report, based largely on the advisors' field notes, answers questions about what it is like to be an advisor, what problems arise in the course of using this approach, and how an advisory system should be designed. Section headings reflect the pilot's major objectives (e.g., Advisors' Personal Problems; Reaction of Teachers). (JA)
