It has been published on the Eurostat website the final report of the third round of Peer Review (2021-2023) with the Improvement actions for Italy, to respond to the recommendations
During 2024, Istat developed a new internal Audit procedure, aimed at improving the quality of production processes and the reliability of the statistics produced. The procedure is based on a three-year planning cycle (2024-2026) in which 3 processes are audited each year

Peer review 2021-2023
The third cycle of Peer reviews for monitoring the implementation of the European Statistics Code of Practice in the NSIs of the European Union is launched.
The publication illustrates the QRCA (Quality Report Card for Administrative Data) portal, developed by Istat to document the quality of administrative data used in statistical processes. The system describes the data lifecycle and measures the quality of the acquisition and pre-processing phases. Born from an international project, it has been adapted to Istat standards and requirements. The implementation leverages metadata and paradata for automatic and real-time updates.
Renewal of the Quality Committee with the aim of reinforcing Istat’s commitment to quality. This body had already been active from 2010 to 2016. Moreover, for the first time in Istat, the figure of the Quality Manager was created.

The first version of the QAF included methods covering only a few indicators of the Code, it will be integrated several times until version 2.0 covering all principles.
The Sponsorship on Quality (2009-2011) is an high level ESS Committee Task Force. Its mandate was to develop recommendations for possible modifications of the Code of Practice as well as recommendations to enhance quality-related activities.
The task force proposed some revisions of the European Statistics Code of Practice.
Moreover, the Task force provided a preliminary version of the Quality Assurance Framework for the implementation of the Code and developed recommendations on quality reporting.
The European Statistical System Committee approved the task force work and recommendations in September 2011.
