Schulmädchen-Report: Was Eltern nicht für möglich halten (Schoolgirl Report Part 1: What Parents Don't Think Is Possible) (UK release title: Confessions of a Sixth Form Girl) is a 1970 West German sex report film directed by Ernst Hofbauer and produced by Wolf C. Hartwig.

The film is a pseudo-documentary loosely based on the non-fictional book Schulmädchen-Report by sexologist de:Günther Hunold.

Published by Kindler Verlag (Munich) the same year, the book presented interviews with twelve teenage girls on their sexual lives.

The film was a commercial success in 1970, topping the German cinema charts for weeks, becoming the first in a series that would last thirteen titles until 1980.

The music by Gert Wilden combined beat lounge and acid rock.
