Standards and ratings – HM Inspectorate of Probation Cookies on HM Inspectorate of Probation We use some essential cookies to make this service work. We’d also like to use analytics cookies so we can understand how you use the service and make improvements. View cookies Skip to content Standards and ratings We inspect against published standards designed to drive improvement. They were developed in consultation with service providers, based on evidence, and updated when necessary. The services we inspect know what our standards are, and their services are rated against them. Our inspectors use the standards to ask the right questions and look for evidence to rate the quality of service delivery across each aspect of a service. All services are rated overall as either ‘Outstanding’, ‘Good’, ‘Requires improvement’ or ‘Inadequate’ as well as being rated at the level of individual standards. This will assist services in targeting their improvement activity. Our reports clearly explain why we have given services a particular rating.
