ITCA was instrumental in establishing the Arizona Inter Tribal Trust Fund in 1988 as part of the Arizona-Florida Land Exchange Act which provided that all monetary proceeds from the land exchange of the Phoenix Indian School property were to be deposited into two funds to supplement Tribal education. ITCA and the Navajo Nation agreed to receive the monetary proceeds for deposit into their respective trust funds in the form of a 30-year annuity. The Arizona Inter Tribal Trust Fund will receive $33.2 million at the end of 30 years in addition to the annual amounts. ITCA distributes the income from the Arizona Inter Tribal Trust Fund to the nineteen Tribes in Arizona who were members of ITCA as of January 1, 1988. The funds must be used to supplement educational and child-welfare programs, activities and services for the benefit of those Arizona Tribes receiving the funds. ITCA receives a total of $2 million annually from this fund to distribute to member Tribes. Five Tribes are funded each year on a rotating basis with each Tribes receiving $400,000 every three to four years. Tribes have used these funds for a variety of projects over the years.
