"Not only is bullying once more front and centre as the biggest problem facing our schools, even more people are identifying it as a problem now than a year ago," spokeswoman Shirley Wakefield said.
"The bullying problem has been made worse by the proliferation of cellphones and mobile devices, which has led to growth in cyber-bullying. This is something that is less easy to identify, but potentially just as harmful."
The company said 5 314 pupils, teachers, and family members between the ages of 13 and 34 were interviewed across the country. The survey found that 36% of respondents described bullying as one of the biggest problems at school, compared to 28% a year ago.
Both genders affected
Other issues were having too many pupils in a class, parents not getting involved enough, and a lack of decent toilets.
How big a problem bullying was in schools differed according to age.
Forty percent of 13 and 14-year-olds identified bullying as a major problem, compared to 38% of respondents aged between 15 and 17.
The survey found that both genders were equally affected.
The company said 34% of black respondents believed bullying was one of the most significant problems in their schools, compared to 41% of whites and 43% of coloureds.
The provinces that identified bullying as a major concern were the Western Cape (44 %), the North West (41%), and Gauteng (40%).
