The Education Minister has confirmed that Carrickfergus Central Primary School will transfer to integrated status from September 2021.
Some 86% of parents had voted in favour of the moved, which will now see the school join Acorn Integrated Primary and Ulidia Integrated College in a growing network of integrated schools in the east Antrim area.
Principal Nuala Hall said the news that Peter Weir had approved the proposal has delighted everyone connected with the school.
"We can now continue to build on our already inclusive ethos and our commitment to welcoming pupils from all backgrounds," she said. "Children are at the heart of the school and the school has been at the heart of the local community for the past 68 years.
Ms Hall added: "We look forward to providing a quality, inclusive education for the children of this area for the next 68 years and beyond."
Ian Baxter, Governor of Carrickfergus Central Primary School, said the decision was the culmination of years of effort by all involved.
"Everyone who worked so hard to ensure this success, in particular all the school staff, parents, governors and colleagues within the Integrated Education Fund and Northern Ireland Council for Integrated Education," he said.
"I would also like to thank everyone who supported the transformation process."
Tina Merron, Chief Executive of The Integrated Education Fund (IEF), also expressed its delight.
"The school has been working towards this for a number of years and the whole school community have been involved throughout the process," she said.
Among the other schools which have undergone the process are Glengormley High School; Bangor Central Nursery School; Brefne Nursery School in Belfast; Harding Memorial Primary School in Belfast, St Mary's High School in Brollagh, Fermanagh; and two small rural Catholic Maintained primaries, Ballyhackett near Coleraine and Seaview in Glenarm.
While DUP Education Minister Peter Weir recently rejected the development proposal from St Mary's High School in Brollagh, he has however approved the move at Seaview Primary School, who will be transforming to integrated status in September 2021.
