General Funds and Lottery Money are both great sources.
LCAP Funds (California) - All-American Student Classic fits very well with LCAP funding.
Title I Program (Federal Funding) is very flexible and is also a good fit.
There are a number of unrestricted monies which qualify for funds that can be used for the All-American Student Classic. The key is to talk to your district superintendent (they love to hear about the AASC) and have been known to visit campuses running the program to see what all the excitement is about. This program aids the district in meeting its educational goals.
