Claudia Beyer was born in Berlin. She achieved the Abitur at the humanistic Gymnasium Steglitz [de] in Berlin-Steglitz. She trained to be a certified economy correspondent (Wirtschaftskorrespondentin) for English and Spanish. Beyer intended to become an architect, but found the field in West Berlin to be saturated with architects and short on available property lots, due to the Berlin Wall. She instead studied pedagogy at the Pädagogische Hochschule Berlin [de] (PH), graduating with the Diplom. She worked from 1972 as correspondent for the foreign department of a wholesaler, moving the following year to a position as research assistant of the Deutsche Gesellschaft für die Vereinten Nationen [de] (German society for the United Nations). She then became its CEO for the Berlin region from 1976 to 1979. She also lectured from 1977 to 1979 at the PH Berlin at the chair of Bildungsplanung [de].
