Our Core Values


People First: The Arc of Harris County believes that all people with intellectual and developmental disabilities are defined by their own strengths, abilities and inherent value, not by their disability.


Equity: The Arc of Harris County believes that people with intellectual and developmental disabilities are entitled to the respect, dignity, equality, safety, and securities accorded to other members of society, and are equal before the law.


Community: The Arc of Harris County believes that people with intellectual and developmental disabilities belong in the community and have fundamental moral, civil, and constitutional rights to be fully included and actively participate in all aspects of society.


Self-Determination: The Arc of Harris County believes in self-determination and self-advocacy. People with intellectual and developmental disabilities, with appropriate resources and supports, can make decisions about their own lives and must be heard on issues that affect their well-being.

Diversity: The Arc of Harris County believes that society in general and The Arc of Greater Houston in particular benefit from the contributions of people with diverse personal characteristics.
