A cooperative is a legal entity that is owned and democratically controlled by its members. Members often have a close association with the enterprise as producers or consumers of its products or services, or as its employees.

Cooperatives may take the form of companies limited by shares or by guarantee, partnerships or unincorporated associations.
A group of deaf professionals can set up a co-operative to share, for instance, interpreter services and other resources. They could work together in the same building to create a sign language friendly environment. Or they can work across the country, e.g. as independent sign language teachers, who share resources such as learning materials, maybe develop a joint website, or a joint identity and quality standards, etc.
