Peer reviews are part of the European Statistical System (EES) strategy to implement the Code of Practice (CoP).
Their objective is to enhance the integrity, independence and accountability of the statistical authorities which make up the ESS.
A first round of peer reviews was carried out in 2006-2008. A second round was launched in December 2013.
Both rounds cover all the EU Member States and the EFTA Member States Iceland, Liechtenstein, Norway and Switzerland.
