For more than 25 years, MENTOR: The National Mentoring Partnership has provided the youth mentoring field with a set of researched-informed and practitioner-approved practices for creating and sustaining positive and impactful mentoring relationships and strong program services. The fourth edition of "The Elements of Effective Practice for Mentoring"" ("Elements") represents the current evidence-based standards for running a safe and effective youth mentoring program. This guide serves as a supplement to the "Elements" and includes additional recommended practices focusing on boys and young men of color (BYMOC). The creation of this guide is motivated by a recognition of MENTOR, My Brother's Keeper Alliance (MBKA), practitioners in the field, and researchers specializing in mentorship of youth of color that BYMOC are better served with a targeted set of practices, which represent enhancements of those in the original "Elements." The recommended practices found in this guide are emergent, based on recent research and recommendations from researchers and practitioners in the field. The "Guide" is divided into two parts. Part one offers an overview of an approach to mentoring BYMOC, including a description of a strengths-based and liberatory approach to mentoring called "critical mentoring." This section discusses how this approach can support BYMOC, and concludes with a rationale for this new, emerging set of recommended practices. Part two includes sections dedicated to each of the six Standards of practice in the fourth edition of the "Elements." Each of the six sections begins with a description of the original Standard and the rationale for its importance, followed by a list of the additional recommended practices, and a discussion section that explains their theoretical basis and potential application in programs. The following are appended: (1) Benchmarks and Enhancements of "The Elements of Effective Practice for Mentoring""; (2) Glossary of Terms (with Explanation of Relevance to Mentoring); and (3) Methodology. Includes the fourth edition of "Elements of Effective Practice for Mentoring"."
