The Bishop of Llandaff admits up to 180 students into each year group. In keeping with the Christian character of the school the governing body, who are responsible for admissions, allocate 150 'foundation' places and a further 30 'open' places. A ‘foundation’ place is reserved for those students who are from Christian backgrounds, either Church-in-Wales or another Christian denomination. An 'open’ place is intended for those families who wish their child to be educated at The Bishop of Llandaff as their preferred faith school.
