Certification of addiction support institutions
(QuaTheDA:2012 looses its validity per June 30th, 2023 and will be replaced by QuaTheDA:2020.)


QuaTheDA is a quality project run by the Federal Office of Public Health (FOPH/BAG) for addict support, addiction prevention and health promotion which seeks to inspire confidence in the capacity of organisations to provide quality services. The SQS has many years of experience and expertise in the certification of addict support, addiction prevention and health promotion services. It is a leading evaluation and certification organisation for quality systems and management systems and this guarantees the prestige and acceptance of the QuaTheDA certificate.


QuaTheDA forms the basis for the continual improvement of the service. The QuaTheDA certificate may be a requirement for concluding a service level agreement with a specific canton. Organisations which are certified to Module I standard «Residential addiction therapy and rehabilitation» meet all the conditions set out in FSIO-DI 2000 and can also be issued on request the FSIO-DI 2000 certificate.
