Pupils are happy and safe at Greenbank School. They told inspectors that staff support them well. This helps pupils to believe in themselves. Pupils described the many ‘fun’ activities that they experience at school or in the residential provision after school, such as learning to shop or cook for themselves. Pupils benefit from these, and other, carefully selected opportunities. They grow in confidence and independence. The school is a calm and harmonious place. Pupils get on well with each other. They learn how to respect each other’s differences and points of view. Leaders quickly identify any incidents of bullying and deal with them well. Leaders have high expectations for pupils’ behaviour and attitudes to school. Pupils are polite and respectful. They embrace the welcoming and supportive culture that leaders have established. Pupils can be trusted to move around the school independently and safely. Leaders’ expectations of what some older pupils, and students in the sixth form, can and should achieve are not high enough. Pupils, including students in the sixth form, do not achieve as well as they should.
