The Department of Community and Cultural Affairs (DCCA) has broad responsibility over a wide range of areas. These include functions in the area of social services funded in whole or in part by federal funds; historic and landmark conservation and preservation; activities to preserve Chamorro and Carolinian heritages and traditions; youth services; and broadcasting.

DCCA accomplishes its mission through eight divisions.  The DCCA Office of the Secretary oversees the operation and administration of the department, in addition to providing utility subsidies to low-income families, promoting energy conservation, licensing child care providers, and operating a weekly street market.  The Office on Aging provides assistance to senior citizens and caregivers.  The Chamorro Carolinian Language Policy Commission preserves and promotes indigenous languages.    The Commonwealth Council for Arts and Culture facilitates meaningful and quality art programs.  The Nutrition Assistance Program safeguards health and well-being by raising nutrition levels.  The Historic Preservation Office protects and develops historic and cultural properties.  The Division of Sports and Recreation develops and administers sports programs.  The Division of Youth Services promotes the well-being of children, youth, families and the community as a whole.

DCCA employs 173 workers: 66% indigenous Chamorros, 28% indigenous Carolinians, and approximately 5% other ethnicities.
