Treetops is a large mixed day, community special school which provides mainly for pupils with moderate learning difficulties although many pupils have complex learning needs. An increasingly significant number of pupils have autism, speech and communication difficulties and developmental delay. The school was designated as a Teaching School in March 2012. The headteacher is a National Leader of Education and the school is a National Support School. A range of training and support is provided to other schools in the local authority area and more widely. All pupils have a statement of special educational needs, which specify complexity of need and levels of attainment. The vast majority of pupils are from White British backgrounds, and very few speak English as an additional language. A third of the school’s pupils are supported through the pupil premium (additional government funding for disadvantaged pupils) which is well above that found nationally.
