The area remained largely a rural, farming community. Small merchants had businesses located in Groesbeck, Bevis, and Dunlap. One had to travel to Mt. Healthy or College Hill for entertainment or evening dining. However, there was enough growth in the community to warrant the construction of a second building that became Colerain High School from 1931 – 1964. The building accommodated student in grades 7 – 12. The Board of Education instituted a policy that it would provide textbooks for students eliminating the need for each student to incur the expense. Without this step, it is likely that enrollment would have decreased as the Great Depression put a significant economic strain on families in the community. Because of the Depression, many students did not complete twelve years of school, as they were needed to help provide for their families. Typically, there were 20 – 30 graduates each year.
Classes were limited to English, Math, Algebra, History, Government, Science, and Latin. Everyone took the same classes as separate College Preparatory or Vocational programs did not exist. Student activities continued to be centered around the band, glee club, school plays, and athletics. The first yearbook was published in 1940, but was suspended during 1944 and 1945 due to wartime rationing programs.
Prior to 1935, boys competed in interscholastic Soccer with Football beginning in 1935. Carl Crawford coached the first Football team. Colerain fielded an eleven-man football team in 1935 and 1936. Football was not offered in 1937 and 1938 and boys played fast pitch softball in the Fall during those two years. The Football program was restarted in 1939 and Colerain fielded six-man teams until 1948 when the program was restored to the version that everyone knows today.
Girls continued to play Basketball through the 1930s. The 1939 – 40 squad won the Hamilton County League Championship. Interscholastic competition for girls ceased the following year as the governing body made a determination that girls shouldn’t be allowed to compete due to risk of injury. Athletics for girls were suspended until the 1950s when the GAA was established primarily to provide intramural competition. GAA was active until the middle 1970s when interscholastic athletics were reinstated for girls with the passage of Title IX.
