Context: Gesamtschulen might put bright working class students at risk according to several studies. It could be shown that an achievement gap opens between working class students attending a comprehensive and their middle class peers. Also working class students attending a Gymnasium or a Realschule outperform students from similar backgrounds attending a comprehensive. However it is not students attending a comprehensive, but students attending a Hauptschule, who perform the poorest.
