The Electroconvulsive Therapy Accreditation Service (ECTAS) was launched in May 2003. Its purpose is to assure and improve the quality of the administration of electroconvulsive therapy. Participating clinics undergo a process of self- and peer-review. The Royal College of Psychiatrists' Court of Electors will award an accreditation rating to clinics that meet essential standards; this accreditation will last for 3 years, subject to annual self-review. Participating clinics will also receive feedback and advice about local strengths and areas for improvement. The accreditation service is endorsed by the Royal College of Nursing and the Royal College of Anaesthetists and has the support of the Healthcare Commission in relation to English services. Clinics that participate in ECTAS will be listed on the College website, with the accreditation rating awarded.
