Schools are illegally pressuring difficult students to leave and an independent authority needs to be set up to review expulsions and exclusions, a community law advocate says.
The push for change comes as figures obtained by the Herald show that one school used suspensions more than 100 times in an 18-month period.
A principals' federation has rejected the call for independent reviewing of exclusions and expulsions - but says the figures are troubling and an overhaul of how problem students are taught is needed. Since 2012, 692 schools have suspended students a total of 4,761 times, resulting in 1,760 students being kicked out, information obtained under the Official Information Act shows.
A suspension is the formal removal of a student from a state or state integrated school until the board of trustees decides to lift the suspension, extend it, or make the student leave school (exclusion for children under 16 and expulsion for those who are older).
Western Heights High School, which has a roll of around 1,560, had the highest number of suspensions with 104, resulting in 16 exclusions and fewer than five expulsions.
