Benefits of Volunteers Cited by Nine in Ten Charities. We asked charities about the extent to which volunteers provide certain kinds of benefits to their organization and whether benefits are provided to a great or moderate extent. The results are presented in figure 6 below. We learned that charities are generally enthusiastic about the benefits volunteers provide. A majority of charities cited five of the six items as beneficial to a great extent. When including those charities that claimed benefits at only a moderate level, more than 90 percent of respondents cited these five items. Fewer charities benefit from specialized skills, such as pro bono legal, financial, management, or computer expertise. A Measure.
