This document introduces tools and resources called Skills-Plus that are designed to help non-profits structure volunteer opportunities to develop workplace skills and competencies. It describes the six Skills-Plus tools, which include a volunteer opportunity template, sample opportunities, a competency matrix, and a skills-based volunteering card game. The purpose is to facilitate linking volunteer experience to career development so that non-profits, workplaces, and volunteers can better define and measure the benefits of employer-supported volunteering.
