rterly aggregate data collection called the RIIA Quarterly Dataset, to provide in-year benchmarking and early trend analysis across a suite of high-level performance measures. The SSD should, as our work to support it develops, be capable of producing the bulk of the RIIA dataset for LAs without bespoke local data work. The SSD may, if adopted across the sector, increase the potential scope of the RIIA collection; the exercise is limited in order to keep its outputs timely for leaders, and low impact for data officers who must produce the dataset alongside other duties. Should the SSD succeed in facilitating broader standard data output from LAs, it could be used to produce a broader dataset on behalf of LAs to support their in-year analysis. 7.4. The DfE CIN Census and SSDA903 Should DfE look to revise statutory collections in light of the above-discussed data development projects, the SSD should adapt in light of these changes, and the SSD should also be considered as a possible venue for data sharing between LAs and DfE. The CIN Census and SSDA903 collection have been DfE’s primary mechanism for understanding children’s safeguarding data for around two decades; they are long-established processes well- integrated in local business processes, CMS products, and national policy work. DfE’s new data strategy for children’s social care may result in significant change to these collections, and the SSD and its project partner organisations are well-placed to support any such change. 17 7.5. The Data to Insight sector-led service Data to Insight (D2I) is the sector-led service for children’s safeguarding data professionals. Maintaining sector-critical data tools, data collections, and learning venues, D2I provided the technical team for the SSD project, as well as convening
