CERN currently has 23 Member States, the list of which can be consulted on the CERN website. Romania has been officially collaborating with CERN since 1991, when the first Agreement on the participation of Romanian institutions in the Organization's programs was signed. In 2010, Romania signed the Agreement on the status of candidate for accession to CERN, an agreement ratified by Law no. 203/2010 and which defined the framework for collaboration with CERN, for a period of 5 years, in order to join as a CERN Member State with full rights. In June 2015, the CERN Council unanimously approved Romania's accession to CERN as a Member State with full rights. In 2016, the Law for Romania's accession to the Convention for the establishment of a European Organization for Nuclear Research was adopted.
