Plans to double the pupil numbers at the Trinity School in Sevenoaks have been announced by its governing body.
The Sevenoaks district’s Christian secondary school says it will begin a formal consultation in January on increasing entry numbers from 120 to 180.
The move comes after the school was approached by Kent education chiefs to help meet an increase in demand for secondary school places in Sevenoaks.
If it gets the go-ahead it would mean Trinity would gradually increase numbers from just under 600 to 1200 pupils – 100 fewer than neighbouring Knole Academy.
Trinity opened with just 92 pupils in 2014, and shares the Wildernesse site off Seal Hollow Road with the town’s Weald of Kent Grammar School annexe, which opened this September.
But chairman of governors, Bill Lattimer said there was enough room for 10 entry classes split between the two.
Trinity currently admits four Year 7 classes which would rise to six if the plans are agreed, while the grammar annexe takes a further three forms.
But a large increase is bound to lead to fresh concerns about parking and access to the site.
Mr Lattimer told Kent Live he was keen to stress no final decision had been taken.
“This is not a done deal,” he said.
“Before any decision is made we will start a consultation with local residents and local organisations in January. Their views will be heard before any formal decision is made.
“There is plenty of room on the site but I want to say anybody who is concerned about it will have the opportunity to put their point of view forward during the consultation.”
Trinity, which currently has around 600 pupils, is “very oversubscribed,” said Mr Lattimer and the larger intake would allow “more children to come.”
But he denied the school would be taking pupils from other Sevenoaks secondary schools.
“There are larger numbers coming through from primary schools and they have to go somewhere. Kent County Council asked us if there was a way we could take them,” he said.
The school admitted 180 pupils last September as an emergency measure after being asked to do so by Kent County Council.
This was likely to be repeated next September, Mr Lattimer added, and the arrangement would continue in future years provided the planned expansion gets the go ahead in the New Year.
