Pupils are happy at TreeHouse School and are kept safe. This is because staff are passionate about advocating and caring for their pupils. They enable pupils to communicate using a range of tools, including signs, symbols, vocabulary boards and visual timetables. They know pupils well and are alert to their needs and changes in mood. Pupils follow a broad curriculum. This has been carefully considered to support pupils to develop greater independence. Leaders have high expectations for pupils from their individual starting points. Together with staff, they place a consistent focus on developing pupils’ communication skills. This is embedded through a rich variety of subjects and wider development opportunities. Beyond communication and numeracy, pupils enjoy studying a range of interesting subjects, such as music, art, drama, food preparation and forestry school. While the curriculum is broad, pupils’ learning has not been sufficiently well sequenced in some areas. Where this is the case, pupils find it harder to develop knowledge cumulatively and remember it in the long term. Leaders have ensured that the school is well resourced to meet pupils’ additional needs. For example, pupils have access to a range of sensory rooms and equipment. Staff use these resources effectively to help pupils regulate their emotions and behaviour. The safe outside space, which features sensory gardens and equipment, is also used to support pupils’ health and well-being.
