The Education Review Office has been asked to investigate a perceived culture of bullying within Taieri College, in Mosgiel, following several complaints from parents aired in the media.
The investigation is part of ERO's normal three-yearly review of the school and was instigated by the school's board of trustees during its first meeting with the ERO officer.
About a dozen parents contacted the Otago Daily Times last year, complaining about their children being bullied at the school and about how their complaints were dealt with by school staff.
Board of trustees chairman Shane Boyle said the school was still investigating measures aimed at preventing bullying among pupils.
The installation of security cameras on school grounds was suggested as one possible solution late last year.
Mr Boyle said the school wanted to wait and see the outcome of the ERO review before commenting on any ideas it could implement.
An ERO spokeswoman said she could not confirm it was investigating bullying complaints and could not comment on the framework for the school's review until it was complete.
The review was expected to be completed early next month
