This study considers five different tutor note styles and reports on how the three primary audiences for such notes -student writers, faculty, and tutors -assess their efficacy in terms of length, voice, purpose, and content. Surveys and focus groups reveal that all stakeholders take tutor notes seriously and that collectively they prefer notes that are about a paragraph long, address students directly in the second-person, maintain an institutional rather than colloquial voice, and include a detailed summary and revision plan. To put this study in context, the article also traces the history of writing center scholarship on session reports.
