Evaluation is crucial for writing centers. Given increasingly tight budgets, writing centers should conduct more sophisticated evaluations. Writing centers should turn to educational program evaluation and select general types of evaluation most appropriate for writing centers, and, congruent with the appropriate types, writing centers should design and share small-scale evaluations. Writing centers should emphasize summative evaluations. Six types of evaluation are consumer-oriented, adversary-oriented, management-oriented, naturalistic and participant-oriented, expertise-oriented, and objectives-oriented. The objectives-oriented approach is the best type of evaluation for writing centers. Over the last 3 years, the writing center at the University of Northern British Columbia has implemented a small-scale evaluation plan. A telephone follow-up survey of three groups of clients was conducted. Results indicated that all clients were satisfied with the objectives focused on in their conferences and thought they could immediately apply to their school work what they had learned. There cannot be a single evaluation design for writing centers, but there can be a variety of sound, practical, small-scale evaluation schemes planned, executed, revised, and reported for possible use by others.
