Being supported by the University is not the same as being sponsored. Sponsorship is a formal relationship existing between the organization and the University, and the organization is offically a Sponsored Student Organization (SSO). An organization that is supported by a specific unit does not necessarily imply that the organization is an SSO.
NOTE: Financial support by a University unit is not enough to establish sponsorship. Advertising should accurately reflect the level of support given by a University unit (e.g. If a student organization receives only funds from a University unit, their advertisements may read “Supported by funds from the Office of X” but it may not read “Sponsored by the Office of X.”).
