The report on the 2012 National School Violence Survey (NSVS) findings does not define what constitutes "bullying", although cyber-bullying or online violence is discussed in some detail. The 2012 NSVS was conducted by the Centre for Justice and Crime Prevention with a sample of 5,939 secondary school learners across all nine provinces. The school-based study included the principal and two educators per school, and followed on from a similar (broader) survey in 2008. The sample of secondary schools was stratified by province, with the sample being drawn proportionate to size. The DBE Education Management Information System was used as the sampling frame, from which 121 schools were randomly selected. Ten learners from each grade were randomly recruited from those who returned completed informed parental consent, resulting in a sample of 50 learners per school.
Females were slightly over-represented in this study and the age range of the participants extended to 27 years. However the patterns did not vary greatly when only responses from children aged 17 years and younger were analysed.
