Glebe is a secondary special school. All students have a statement of special educational needs. The school caters for a range of primary needs, including moderate learning difficulties, speech and language difficulties, severe learning difficulties, specific learning difficulties, physical disabilities, visual impairment and behavioural, emotional and social difficulties. A significant and increasing proportion have an autistic spectrum disorder. The school is gradually receiving more students with complex learning needs. Boys outnumber girls in the school. Around three quarters of the students are boys. Around half of the students are eligible for pupil premium funding and this is well above the national average. This is government funding to support the learning of students eligible for free school meals and those who are looked after by the local authority. The proportion of students from minority ethnic groups is around the national average, and a small minority of students speak English as an additional language. The majority of Year 11 students and some members of the sixth form attend Bromley College for one day a week. There is currently a building programme underway to enable the school to cater for an increased number of students.
