 In 1994 the school governors decided to change the name from Grammar School to College in order to reflect the reality of their service to the whole community.In 2015 Northallerton College merged with Allertonshire School to form Northallerton School.The school still operates over both of the former school sites, with the lower school on Brompton Road (the old Allertonshire School site) due to be renovated over two years from 2019 and the senior school and sixth form on Grammar School Lane (the old Northallerton College site).
