Web Panel Sample System (WPSS) is a web application coupled with a survey platform (a Qualtrics dedicated license) to meet the needs of high-quality cross-national probability-based online panels. The WPSS enables a centralised management of a cross-national sample for academic studies, be it in the Social Sciences and Humanities field or beyond. A prototype of the WPSS has been developed and extensively tested in 2021 within 11 European countries. Starting October 2021, a new release of the WPSS will support its first full-scale use case, within the frame of ESS ERIC for its web panel spinoff the ESS round 10 (funded under ESS-SUSTAIN-2).
