The Regional Ethical Review Board of Stockholm (ref. no. 2010/241–31/5) has therefore decided that analyses of data from the SSS are not subject to consideration for ethical approval. Informed consent was obtained from the students who participated. Due to the procedure of anonymous completion of the questionnaire, active written or oral consent was not applicable. The collection and analyses of the Stockholm Teacher Survey (STS) have been approved of by the Regional Ethical Review Board of Stockholm (ref. no. 2015/1827–31/5).
