This paper is a data quality statement which relates to information held by CARIS, the Congenital Anomaly Register and Information Service for Wales. The statement describes compliance with a set of six standards set by the Audit Commission in 2007. The standards were designed in order to define arrangements that public bodies could adopt to drive improvement in the quality of their data, building confidence in the data used by all public sector bodies and partnerships. While the Audit Commission closed in 2015, the standards are still in use by many public sector bodies. A seventh standard on accessibility has also been included.
