The members of the Schengen Information System II Supervision Coordination Group (SIS II SCG) and the Coordinated Supervision Committee (CSC) conducted a coordinated inspection activity concerning the Schengen Information System (SIS). The SIS is the most widely used and largest information sharing system for security and border management in Europe.

Within the scope of the inspections, the alerts and procedures with regard to Article 36 of the SIS II Decision were checked, as there has been a Europe-wide increase in the number of alerts in this alert category. In order to achieve comparable results, a questionnaire was developed by the SIS SCG and used by the Member States for their inspections.

The results indicated various differences between the nineteen Member States which took part in the coordinated inspection activity, enabling the CSC to draw conclusions and to recommend the necessary measures with regard to the documentation of the alerts, their quality, the time limits and retention period, as well as substantive and technical issues.
