This created the conditions for the Swedish Army's military personnel to receive a comprehensive supplementary education in general subjects.

[3] Its duties were to "provide permanent staff and conscripts from the Army, Navy and Air Force, the general education required to gain employment as an officer or non-commissioned officer on active duty as well as the knowledge of technical subjects relevant to the service in certain special military branches."

The fältflygare received the same education in general subjects as the students of the Air Force's non-commissioned officers program.

[3][4] As a result of the new eligibility rules in general subjects which were established by the government in June 1977, a secondary education two-term course for platoon officer candidates in the Army who had no secondary education or only limited such was carried out as of January 1978, instead of the supplementary and additional training which was previously granted.

For regimental officer candidates with only compulsory school (grundskola) competence, comparable education was conducted as for company officer candidates so that teaching in Swedish corresponded to the requirements for three-year upper secondary school (gymnasieskola).

In order to be allowed to apply to the army's regimental officer course or to equivalent education in other military branches, education was also given according to the curriculum of the upper secondary school's three-year natural science or social science program.

[3] For the regimental officer candidates who only needed supplementary Swedish and German organized distance education were arranged, which was a combination of correspondence studies and classroom-based teaching.

This meant that 3-5 days of intensive studies with teacher guidance were conducted at FGS every month.

Then the assignments were also prepared for the coming home study period, during which the students were able to contact the teacher by telephone in their respective subjects.

On 19 September 1944, the school was transferred to a newly built building at Dag Hammarskjölds väg 31.
