In February 2005, the Statistical Program Committee (CPE) adopted the European statistics Code of good practice and undertook to observe the fifteen principles established therein, as well as to periodically review their application using the Good practice indicators corresponding to each of the fifteen principles.

This Code has been embraced by INE by way of a resolution by the Board of Directors, which thus undertakes to comply with the aforementioned when establishing the general principles regulating the generating of statistics for State purposes. In this way, INE endeavours to guarantee an improvement in the service it provides to society, which will undoubtedly reinforce its image as an institution.

In May 2005, the CPE agreed a formula for monitoring implementation of the Code, for a duration of three years. During that period, the various countries must carry out quality self-assessment, taking as a reference the aforementioned Good practice indicators, which in turn must be contrasted and checked via so-called peer reviews. The end result will be a report submitted to the Board and to the European Parliament in 2008.
