Eastwood attended Piedmont Middle School, where he was held back due to poor academic scores, and records indicated he also had to attend summer school. From January 1945 until at least January 1946, he attended Piedmont High School, but was asked to leave for writing an obscene suggestion to a school official on the athletic field scoreboard and for burning an effigy on the school lawn, on top of other school infractions. He transferred to Oakland Technical High School and was scheduled to graduate mid-year in January 1949, although it is not clear if he did. "Clint graduated from the airplane shop. I think that was his major," joked classmate Don Kincade. Another high school friend, Don Loomis, echoed "I don't think he was spending that much time at school because he was having a pretty good time elsewhere." "I think what happened is he just went off and started having a good time. I just don't think he finished high school," explained Fritz Manes, a boyhood friend two years younger than Eastwood, who remained associated with him until their falling out in the mid-1980s. Biographer Patrick McGilligan notes that high school graduation records are a matter of strict legal confidentiality.
