This document contains the National One to One Mentoring Partnership kit, designed to help users better understand what mentoring is and how they can support it in its many variations. The National One to One Mentoring Partnership is described as a new coalition mobilized to provide mentoring opportunities to youth, with the goal of giving every young person who might benefit from a mentoring relationship the opportunity to be matched with a caring partner by the year 1995. The kit briefly describes the Mentoring Partnership; presents a case for mentoring and examples of 14 issue-related mentoring programs already in existence; provides guidelines for corporations and organizations interested in joining the National One to One Mentoring Partnership; and describes ways to get involved in mentoring, along with names, addresses, and brief descriptions of resource organizations. Also included are two mentoring case studies and a number of anecdotal and statistical references that illustrate the crisis in youth development in the areas of school dropouts, functional illiteracy, youth unemployment, poverty, teenage pregnancy, substance abuse, juvenile crime, child abuse, and runaways.
