Operating model

Revenue model
Earned-program. 69% of the money available for current operations came from fees and other program revenue.
Distribution model
Transfer-based 990-EZ. The 990-EZ reports grants or member benefits, but it does not separate enough spending to show the nonprofit’s full delivery mix.

The verdict

MIXED - The filed numbers largely add up and revenue comfortably covers expenses. A relatively small share of available resources goes toward mission work and program spending has declined or grown slowly.
