When the student cap came out, it was only connected to studentereksamen (STX) which at that time was the only upper secondary level education there was, and was connected to a very high status, because very few people graduated. From the 1970s three other upper secondary level educations were made. Higher Preparatory Examination (HF), Higher Commercial Examination Programme (HHX), and Higher Technical Examination Programme (HTX). From about 1990 there has also been student caps for other educations, including 10th grade and SOSU. More variants of the caps are still being developed with special coloured cords and badges, because more educations want their own cap.
