Aims: To investigate whether the operations of Continuous Professional Development (CPD) peer groups, within a mental health service in North East England, were compliant with guidelines and recommended standards for continuous professional development. Tees, Esk, Wear Valleys NHS Foundation Trust is one of the largest mental health providers in the United Kingdom. It had 33 identified CPD peer groups at the time. Methods: Standards were derived from the Continuing Professional Development Guideline of the Royal College of Psychiatrists, UK. An audit proforma was generated based on the standards and questionnaires were created to identify compliance with standards. This was an audit conducted as an electronic questionnaire survey, as reported by coordinators of identified peer groups. This was conducted in November 2013. Results: Thirty (30) peer group coordinators responded (response rate of 90%). Twenty-Seven (27) groups (90%) had all members enrolled in an approved CPD programme. Twenty-Three (23) groups (76%) met the recommended size of membership. A coordinator was clearly identifiable in 27 groups (90%). All groups do undertake review and identification of learning objectives. Twenty-Five (25) groups (83%) do approve CPD activities and award credits. Twenty-Nine, 29 (96%) document meetings. Twenty-Eight, 28 (93.3%) do provide advice, remedies and support. Twenty-Eight, 28 (93.3%) do sign off CPD portfolios. Areas needing improvement were the provision of evidence of attendance to learning activities and evidence of reflection (80%); and invitation of external observers to observe peer group meetings (43.3%). Conclusion: These results give confidence that continuous professional development is occurring to envisaged standards. To improve practice, groups should consider incorporating the approval of CPD activities and credits into
