This bulletin focuses on workplace mentors for all students involved in work-based learning as required in the School-to-Work Opportunities Act. It reviews these key issues that should be addressed in developing an effective mentoring component in a school-to-work system: a recruitment plan for mentors; eligibility screening for mentors and students; mentor training; training sessions for students; matching students with mentors; a monitoring process and ongoing support and training; and closure steps. Two effective practices are described: (1) the Rochester, New York, school-to-work mentoring initiative that is part of a comprehensive mentoring initiative that also includes four components--workplace, community-based, school-based, and adult mentoring; and (2) the Hospital Youth Mentoring Program administered by the Johns Hopkins Hospital (Baltimore, Maryland), which has supported youth mentoring initiatives at 15 hospitals across the country. Contact and address information for the two programs is provided. The bulletin then lists seven organizations that can provide further information on the topic. Brief summaries describe the organizations' focus and activities. Fifteen resource publications are listed. (YLB)
