Summer School Teachers (1974) Barbara Peeters

A trio of naive, but eager young Midwestern women go to California to teach summer school classes at Regency High School: Perky and willful Conklin T. starts up and coaches an all-female football team, stuffy chemistry teacher Sally Hanson manages to loosen up after she falls hard for a surly juvenile delinquent student, and pert and liberated photography instructor Denise Carter becomes involved with both a two-faced male chauvinist jerk and a more decent and understanding guy.

Summer School Teachers is funny, fast-moving, well-acted, and well-written despite the cliche sex comedy tropes (dirty-minded old women, leering faculty, outraged parents, and gym showers) with such lines as "You give a guy an inch, he takes two, you discover he's got only three, and pretty soon you've got nothing."
