 The community of Bettendorf quickly grew during the 1950s and 1960s, and by the early 1960s, the district had outgrown the school due to increasing enrollment.Students walked to some classes in rented store fronts on State and Grant Streets, while an annex building (which later became Neil Armstrong Elementary) also helped serve students.By 1971, with enrollment still growing at a fast pace, plans were started to build a new high school along 18th Street in the northern part of the city, roughly 1½ miles north of Middle Road.
