Typically, students enrolled in clinic programs represent clients singularly or in teams of two or three. Each student also meets in a classroom forum with their clinical instructor once a week. Classes are devoted to teaching about substantive law, practice skills, professional responsibility, problems in the administration of justice and system reform. In their clinic practices students give advice to individuals and groups and engage in formal and informal advocacy, as well as transactional work. Student attorneys do a significant amount of writing by drafting letters, pleadings, agreements and organizational documents, legal memoranda and briefs. They are also responsible for the client files, both in paper and electronic forms, and they must complete a timesheet at the end of each week.
