Maltreatment including severe corporal punishment, constant verbal and emotional abuse, sexual harassment and sexual abuse, sleep deprivation, forced manual labour and isolation has been alleged by many former students
In February 2020, a judge presiding over a class-action lawsuit on behalf of former students found the staff at Grenville Christian College responsible for systematically abusing girls and boys who attended the boarding school in the 1970s, '80s and '90s. The school's appeal is being heard in court.
