It highlights the centrality of service user involvement to the programme’s design and delivery. Advantages for service users, staff, services and commissioners are outlined with feedback from different stakeholders included. Psychological therapies services need to be aware of this option to achieve accreditation from a body specifically tailored to evaluate such services. The programme is aligned to the Care Quality Commission’s five domains, utilising a supportive model of peer review, through which participating services are encouraged to share good practice and learn from one another. The process revolves around the APPTS standards, which have been developed collaboratively with key stakeholders, staff from member services, and representatives with lived experience, and provide the framework for what a high-quality psychological therapies service should look like.
