This booklet provides step-by-step guidelines for developing a leadership-through-service-learning component for a school athletic team. It is based on a program called LIFE LINE (Leaders in Football and Education) founded in 1996 as a peer leadership group that would increase team unity and success both on and off the field. The guide summarizes the LIFE LINE experience, then sets out the following five steps for developing a peer leadership group: (1) choose a facilitator; (2) select peer leaders; (3) set up retreat plans; (4) train peer leaders; and (5) turn community service into service learning. The next section provides more information about the service learning model, including selection and planning of projects, the need for committed and ongoing action, maintaining the commitment of peer leaders, reflective writing, oral reflection, recognition and celebration, and suggested service activities. A list of four service-learning resources is included in the guide. (KC)
