Research has been conducted regarding what relationship demographic diversity have to organisational ambidexterity and team resilience; however never at the same time. This research adds a new context, to this field of research since research has never, to our knowledge, been conducted in a school context.

The purpose with this thesis is to explain what relationships gender, age, cultural and tenure diversity have on organisational ambidexterity and team resilience. A cross-sectional research design was used, because of the positivist and deductive approach. The method consisted of a quantitative part in the form of a web based self-completion questionnaire mediated by email, to upper secondary schools, in five Counties, with a minimum of three managers. The qualitative part was in the form of three in-depth interviews, two with School Directors and one with a registrar.

The findings shows that gender, culture have a negative relationship to organisational ambidexterity, and age have a positive relationship when moderated by shared vision.

The limitations are that only schools with a minimum of three top managers were chosen; the results thereby lack generalisability in other contexts. The implications are that shared vision, when applied to an upper secondary school context seem to decrease in importance and suggestibility.

The original value of the conducted study is new insights regarding the relationships demographic diversities have on organisational ambidexterity and team resilience; the choice to conduct the test in a school context.
