About 40 members of the community met the board of trustees on Friday night to discuss the school's future.
The meeting was held after Education Minister Anne Tolley announced last week consultation had begun on the restructuring of six South Dunedin schools, including Calton Hill School, and presented options for dealing with the increasing number of empty classrooms.
One option is to merge Forbury and Macandrew Intermediate schools into a years 1-8 full primary school on the Macandrew site, merge Caversham, College Street and Calton Hill schools into a years 1-8 full primary school on the Caversham site, and change St Clair School to a years 1-8 full primary school.
Another option is to close Macandrew Intermediate and merge Caversham, College Street and Calton Hill schools into a years 1-6 contributing primary school on the Caversham site.
Mrs Tolley has called for other options to be presented by school communities by December 14.
Principal Glenda Jack said the Calton Hill community raised many concerns about merging the school with Caversham and College Street schools and was now formulating other options to present to Mrs Tolley.
"Our community is not supporting the merger with Caversham and College Street schools.
We are in the Corstorphine, Calton Hill, Kew area - not Caversham or South Dunedin."
Mrs Jack said concerns included the distance pupils would have to travel to go to school "on the flat", the cost of public transport and the loss of the community's playcentre and Civil Defence post situated on the school grounds.
It was also noted the school's roll of mostly Pacific Island pupils had been increasing during the past two years, she said.
The idea of merging Calton Hill with Concord School was not discussed at the meeting.
