Several specialised education programmes have moved in and out of Kungsholmens gymnasium throughout its history. In 1984, Stockholms Musikgymnasium () moved into the same building, maintaining a certain level of autonomy as a separate section. The International Section originally existed in Norra Real (an upper-secondary school in Stockholm), but it was transferred to Kungsholmens gymnasium in 1987. The Stockholm City Education Department () announced in October 2014 that the IB Diploma Programme at the school would be moved to the International School of the Stockholm Region (ISSR). This decision was confirmed in November 2014 despite protest actions from students and staff at the school, with new IB Diploma students entering the ISSR in the Autumn 2015 term.
