Campbell stands in an estate of some 100 acres, with extensive playing fields, an elaborate Sports Centre, including Sports Hall, Multi-gym, All-weather Pitches and Tennis Courts, Swimming Pool and Squash Courts. It has an Art centre, with facilities for painting, sculpture, pottery and photography and a new Design and Technology Suite, which caters for work in various media, together with computer aided design and electronics. It has four Physics, four Chemistry and four Biology laboratories, an audio-visual room, lecture theatre, 2 computer rooms, Sixth Form Centre, Assembly Hall, seating up to 750, and a fine Library. In 1988 two new dormitories were opened for third and fourth formers, while in 1989 a block of 30 individual study bedrooms for senior pupils was completed.
Campbell provides a wide range of A level and GCSE subjects from Greek to Technology. In recent years the pass rates in both examinations have been very high and first places in Northern Ireland in a range of subjects have been achieved. Approximately 10% of each year group gain places at Oxford and Cambridge.
Campbell holds an annual Industry Conference for the Sixth Form. Work Experience is now well developed and computerised careers advice supplements the more conventional careers programme.
Campbell has never taken the somewhat narrow view of education that equates excellence with academic excellence alone. The life of a boarding community is dedicated to the total education of young people.
Boys usually enter Campbell at the 11+, 13+ and 16+ stages. Entry at 5+, 7+ and also 11+ is via the Preparatory School, Cabin Hill, which shares the same estate.
