The EuropeSpa certification system consists of the EuropeSpa criteria, the audit and the certificate.

The criteria are regularly evaluated by an international Committee of Experts from the European Spas Association. The quality of spas and health resorts is assessed by an independent auditor on the applicant's premises. Coordination, the operation of the certification system, and the publication of certified providers are all in the hands of EuropeSpa med & wellness GmbH based in Wiesbaden.

Audit: Providers' organisational aspects (e.g. compliance, human resources, quality management and quality assurance) are examined and their facilities are inspected using a checklist. The main audit usually takes 2–3 days. For EuropeSpa med, the control audit about 18 months later usually takes 1 day, while the anonymous control audit for EuropeSpa wellness is performed 8–24 months after the main audit and typically takes 1–2 days.

Passing score: At least 80% must be scored in each section of the audit and all the KO (knock-out) criteria must be met in order to be awarded a EuropeSpa certificate. The decision as to whether to award a EuropeSpa certificate is taken by the EuropeSpa Coordination Centre and the European Spas Association based on the auditor's report.
