After discovering hundreds of early 1900s report cards from the Manhattan Trade School for Girls, Paul Lukas is publishing his findings online in a series called “Permanent Record” on Slate. The written assessments are historical artifacts as well as ephemeral relics of daily life, describing some students as “slow,” and others as “very ambitious,” “irritable at times,” or a “nice type.” (Watch a 1911 documentary on the school here.) In an effort to help these students graduate and get jobs, the girls’ teachers not only gave them failing grades, they also gave F-minuses. And you thought your high-school English teacher was tough.
