Official European statistics are regulated by principles, included in the European statistics Code of Practice (CP), which seek to ensure the quality and credibility of the data. These principles refer, among other things, to professional independence, the protection of confidentiality, the reliability of the results, their precision, timeliness, punctuality, accessibility, clarity, comparability and coherence.
In order to ensure this commitment to quality, the ESS has the European Statistical Governance Advisory Board, created in March 2008, with the objective of exercising independent control of the European Statistical System regarding the application of the Code of Good Practice for Statistics European. This Committee advises the Commission (Eurostat) on the measures that contribute to the application of the CBP, on how to make it known to users and informants as well as on its updating and prepares an annual report evaluating the application of the Code.
In September 2009 was created the working group Sponsorship high level of quality, in which participated the INE, which was primarily responsible for the review of the Code of good practice and the development of quality assurance framework ESS Quality Assurance Framework.
