Make Proof School possible for any kid who loves math.

Proof School has need-blind admissions, and because of the generosity of others, we have been able to meet 100% of demonstrated financial assistance.

Using our "Donate" page incurs a 3.4% charge, which is deducted from your donation. If you would like your full donation to benefit the school, you may send a check payable to Proof School to our address:
