A group that does work with school systems but is diverse and believes in diversity as well as in celebrating ethnic cultures and their history is Projectsouth.  Project South is based right here in Atlanta and they work more from the scope of social awareness and as advocates for disenfranchised groups like those with disabilities, illness, victims of gender/race/sexuality based marginalization, etc:

Founded in 1986, Project South acts as a regional hub for leadership development, movement-building, and long-term strategy development within community-based organizing for racial and economic justice. By creating collective spaces for communities and organizations to develop bottom-up grassroots organizing models, Project South shifts Southern-based organizing from reactive battles to visionary and strategic movement building on local, regional, and national levels.
Project South works directly with young people, intergenerational collaborations, Southern-based organizations, communities affected by social control and violence, cross-regional alliances, and our Atlanta and Southeastmembership base. Our three primary strategies to increase the viability of community-based efforts to shift resources and power
