As communities become more culturally and linguistically diverse, community-based service organizations (CBOs) are called to do more to reduce disparities in access and use of important social services. An important strategy is developing cultural competency—behaviors, attitudes, and policies that enable CBOs to work effectively in cross-cultural situations. This resource guide identifies easily accessible resources on cultural competency that CBOs can use to become more responsive to the needs of their targeted populations, and to help attract funds to support their important work.
