Proposals to convert to grant-maintained status could be initiated by the governing body or by a number of parents, but would then be determined by a ballot of parents.
The total number of pupils in grant-maintained and controlled integrated schools increased from 14,140 in 2000/1 to 17,558 in 2006/6 but only to 21,956 by 2014/15.
In the 1990s and 2000s the school took an early opportunity to gain more independence from local authority control by becoming a grant-maintained school and then a foundation school.
