Bullion Plaza served as a grammar school from 1923 to 1994 when it was closed due to concern that it had fallen into a state of disrepair, making it unsuitable for use as a public school. Most of its life, Bullion Plaza served as a grammar school for Mexican-American and Apache children, reflecting the segregation pattern that prevailed in many Arizona communities including the public school system during that era. The local school system was desegregated and began integrating Anglo students into Bullion Plaza during the 1950-51 school year.
