The cascad certification agency and CASD are partnering to offer an innovative solution to certify the reproducibility of research on confidential data. cascad (Certification Agency for Scientific Code and Data) is the first certification agency for the reproducibility of academic publications. Cascad is a non-profit research support structure (UMS CNRS 2007), funded by various French institutions including CNRS, HEC Paris and the University of Orléans. Certification guarantees the reproducibility of the numerical results (tables and graphs) of a scientific publication, based on a set of digital resources (computer codes and data) used by the researcher. The partnership between CASD and cascad aims to establish secure certification environments that allow a specialized certifier to run the code on precisely identified confidential data (sources, products, version). The Committee on Statistical Confidentiality and the data producers have welcomed this initiative and we thank them very much for it. A pilot will soon start for a period of one year. The CASD will allow the certifier access by providing specific environments for each request, only for the duration of the certification for the data concerned. The certifications will be free of charge for researchers, funded by CASD and cascad, at the rate of one request per project out of a limited number yet to be defined for this pilot phase. If you wish to participate in this pilot, do not hesitate to contact the CASD.
CASD now hosts SSMSI’s statistical databases on recorded crime (2016–2024), covering offences, victims and suspects — researchers can apply for access at cdap.casd.eu.
The EDP Users Committee meets on June 23, 2026 (10:00–12:30) to discuss production updates and the EDP redesign — contributions welcome, contact aurelien.lavergne@insee.fr to participate.
EDDI 2026, the 18th European DDI Users Conference, will be held in person in Brussels from November 30 to December 4, 2026 — with tutorials, conference sessions and a hackathon — and the call for proposals is now open.
CASD had the honour of attending the Constances and Gazel Cohorts Scientific Day on May 26, 2026, where the teams’ innovative work producing health and environment data — and the research built upon it — proved highly impressive.
The Scientific Advisory Board met on May 13 to discuss data documentation progress, a pilot for less sensitive data processing, health-environment research projects, and the potential impact of US data access restrictions on researchers.
