Arizona Private School Tuition Organization (APSTO) is a non-profit School Tuition Organization (STO). We empower investing in our children by providing Tuition Scholarships to children in grades K-12 attending qualified private school in the State of Arizona. All of this is made possible by the generosity extended to APSTO by Individuals and Corporations in Arizona. We are all working together on a mission to bring solutions to educating our children. With your generous donations, APSTO empowers parents with choices to an education that allows their child's highest potential.
