 Both schools housed high school students in part of their respective buildings, but neither school was exclusively a high school.The current facility opened in late 1949 as Euclid Senior High School and had 1,850 students in grades 10–12 during the first school year.The plan for a single high school in Euclid had been the idea of superintendent Russell Erwine as far back as 1930, though plans were not finalized until 1945.
