The Knight Arts Challenge Philadelphia has officially opened for applications. A three-year initiative of the non-profit John S. and James L. Knight Foundation, the Challenge invites grant proposals from anyone—including “established arts institutions, independent artists of all types, businesses, service organizations, and any individual who has a great idea for the arts”—through October 31. Proposals must meet the following criteria:

The idea must be about the arts.

The project must take place in or benefit Philadelphia.

The grant recipients must find funds to match Knight’s commitment.

(From the Foundation’s September news release.)
