NICE quality standards describe high-priority areas for quality improvement in a defined care or service area. Each standard consists of a prioritised set of specific, concise and measurable statements. They draw on existing guidance, which provides an underpinning, comprehensive set of recommendations, and are designed to support the measurement of improvement.

This quality standard covers the recognition, early intervention and management of bipolar disorder, psychosis and schizophrenia (including related psychotic disorders such as schizoaffective disorder, schizophreniform disorder and delusional disorder) in children and young people under 18. For more information see the bipolar disorder, psychosis and schizophrenia in children and young people topic overview.
