According to an August 1958 newspaper article, Avon's new elementary school building was to be used to house students in grades 1 through 6. According to an October 2, 1958 newspaper article, the final cost was $627,511. The population of Washington Township at that time was estimated at 5,000. In 1957, 28 students graduated from the high school. They had 9 school buses covering 18 routes.
According to a December 20, 1956 article, the addition would be built on 12 acres purchased on the west side of the current high school (which had been completed in 1952), and would extend south to the railroad tracks. An outlet to Avon Avenue would be created. The new elementary school would have 18 classrooms and a gymnasium with seating for 1,700 initially, with plans at a later date to seat 3,000 total.
In 1952, total enrollment had been 450 students; in 1956, the enrollment was 830; and was expected to reach 1,000 by the time the new elementary school was finished.
