This is a school for pupils with profound and multiple learning difficulties, physical disabilities, severe learning difficulties and medical conditions. Since the previous inspection there has been a significant increase in the number of pupils, and the school has begun to take pupils with autistic spectrum disorders who have a range of other severe difficulties. Some pupils have degenerative conditions and all the pupils have complex needs. Most pupils are non-ambulant (unable to walk) and many are unable to express themselves through speech. Pupils all have a statement of special educational needs or an education, health and care plan. The proportion of pupils supported by the pupil premium is a little above average. This is additional government funding for disadvantaged pupils who are known to be eligible for free school meals or looked after by the local authority. A high proportion of pupils are of minority ethnic heritage, mainly from Pakistani or Bangladeshi backgrounds. The proportion of pupils from homes where English is not the first language is well above average. The school runs an outreach service on behalf of the local authority for pupils with physical and sensory impairments and associated medical needs. It provides support to 14 high schools, 38 primary schools and five nurseries in Luton as well as some schools in neighbouring authorities. A subject survey led by one of Her Majesty’s Inspectors in December 2011 found that all aspects of the school’s work in physical education were outstanding.
