The number of actual contact hours will vary according to how the service component relates to the rest of the course and the nature of the community partner's needs and conditions. Nevertheless, it should be more than symbolic or an "add-on" activity. Service learning courses should attempt to avoid "one-shot" events (even if they are all-day or all-weekend projects) unless these are parts of a more sustained involvement with the community partner.
If service learning is to seriously challenge student perspectives and enhance student learning, then students must develop a sustained relationship and reflect on a prolonged experience. We recommend that you require no fewer than 15 hours of service in a semester, with 20 - 25 being a good target. Any requirements above 30 hours become prohibitive for students who already work, have heavy courseloads, or are otherwise committed.
