Since 2010, some of the subjects have been taught in English under the new academic structure. In 1996, in response to the development of the school, the Education Department included Choi Kung Pu Secondary School in the list of "Phase 1 School Improvement Scheme", and in addition to the construction of a new wing building in the school car park, a student activity centre, a teachers' lounge, a tutorial room and a meeting room were also added. Air conditioning was also provided to some classrooms and most of the special classrooms on campus. The school's six-storey building has a total of three academic buildings with an area of 80,000 square inches. The school has 27 classrooms, 15 special rooms, two auditoriums, two art spaces, a small chapel, a student activity center, a library, an English corner, an English reading area, a campus television station, two basketball courts, a snack bar and a large garden "Jubilee Garden".
