The instructional concept guide is part of a system developed for tutor training and support. It is primarily designed for volunteers, but it can also be adapted to the training of paraprofessional tutors for any type of adult literacy program. A key component in the system is the Tutor Support Library, consisting of Instructional Concept Guides (training and reference aids for tutors) and Functional Content Units (models for the practical application of tutoring skills). Guide Five suggests concerns and procedures involved in evaluating and modifying the services of an adult literacy agency using volunteer tutors. Assessment and developmental procedures related to program purposes, organizational structure, facilities, staff, tutors, students, and the community are discussed. Included are numerous data collection forms and charts for the evaluation and summary process. (Author/MS)
