An event called "Celebrate Butterfield" was held for the community on May 8, 2010, with a review of the school's history, as well as a reunion of present and past parents, students and teachers. The doors closed forever as the children left for the last time on June 3, 2010. The school's final musical, a performance of "Honk Jr." was held on June 6, 2010. In its closing year, the Butterfield Elementary API tests scores increased to 853, a growth of 76 points, the second largest elementary increase in all of Riverside and San Bernardino counties.
