[8] From its opening in 1975, Langkaer Gymnasium instead became involved in a number of different pedagogical projects and the new school was quickly recognised as an institution that embraced the sometimes experimental development of teaching practices.

A number of former and current students from the school travelled to Syria to fight for ISIS, with police stating that individuals with connections to the Grimhøj Mosque (Danish: Grimhøjmoskeen) had been a catalyst for the group.

However, in 2016, Langkaer Gymnasium was the focus of significant national and international media attention after it became public knowledge that the school had allocated students into classes based on whether they had a Danish background.

[21][22] Jazdani and Bundgaard would later clash on matters such as the students' right to pray in groups as Langkaer Gymnasium sought to solve a unique set of challenges relating to integration.

[23] Langkaer's financial footing had previously been sound, but faced increasing problems as a result of dwindling student numbers coupled with government funding cuts.

Unbeknownst to the school's staff, Yago Bundgaard made contact to other educational institutions in the local area and agreed in principle to a merger with Aarhus Tech.

Despite increased spending on marketing, including advertisements on buses in Aarhus, the decreasing student numbers and ensuing staff redundancies that had marked the final years of Langkaer Gymnasium continued under the school's new leadership.

These fundamental changes to its governance, leadership, staff, and organisational structure were followed by Aarhus Tech's confirmation that a closure of its STX, Hf, Pre-IB and IB programmes in Tilst was imminent.

[27] On October 15, 2018, then Minister for Education, Merete Riisager, had made the announcement that Langkaer Gymnasium had formally merged with Aarhus Tech.

[29] Prior to 2016, high schools in Aarhus had coexisted in a friendly manner, meeting regularly to share pedagogical and leadership practices and there were 'gentleman' agreements with regards to marketing etc.

However, government funding cuts coincided with the increasing problems relating to the distribution of students with non-Danish cultural backgrounds in the Aarhus area.

As such, applicants had become an increasingly important commodity, with falling numbers resulting in staff redundancies, but Langkaer's issues showed that vastly altered student demographics could quickly lead to a decrease in the size of future cohorts.

[41] The cumulative effect of Langkaer Gymnasium's approach could be seen in the results of its graduates, many of whom emphasised the ability of the school's staff to help them develop and improve.

[44][45][46] It was a founding member of the Globale Gymnasier association in Denmark and teachers participated in numerous Comenius, Erasmus and eTwinning projects.
