After a mail conference in 2009 among the organisations of the national mathematics competitions, regulations were issued again for the competition in 2010 and have since then been applied essentially unaltered. For the first time an aim of the NMC is stated in these regulations: The participants should experience a mathematical contest at an international level, and the NMC should provide information relevant for the selection of the teams for the IMO. The participants should be eligible to the IMO, and also other secondary school students are allowed to participate. The mathematical content of the problems is that of the IMO and their intended level of difficulty slightly lower than that of IMO problems. An annual meeting of the Nordic leaders during the IMO, which has taken place traditionally throughout the history of the NMC, is mentioned in the regulations for the first time.
