as Division 3. In principle, each division is to encompass a different type of competition. In Division 1, groups have six teams (meaning more matches and thus more travel), a significant fraction of the players are assumed to be professional or semi-professional (meaning that fixtures are, as often as possible, scheduled within the IRB's international fixtures time windows when clubs must release players for national duty), and only one team is promoted and one relegated every two years (meaning that the competitions are more stable). In Division 2, groups have only five teams each (usually meaning one home match and one away match in the Autumn, and the same in the Spring, for each team), it is assumed that the majority of players are amateurs (meaning scheduling is not as limited), and in addition to the traditional automatic first-promoted-last-relegated system, fourth place from the higher pool will play second place from the lower pool after every two-year competition, with the winner taking the position in the higher pool. From a five-team group, one team is promoted, one team is relegated and two teams play in playoffs. Thus, a maximum of four of a pool's five teams could change from one two-year competition to the next. In Division 3, a single-location, short-time-period (one week or 10 days) tournament is organised once per year. This minimises travel costs for teams and time-off-work requirements for players, and allows the flexibility of having a different membership every year, rather than requiring the membership to be constant over two years. The best performing team over two years of tournaments is promoted to Division 2. In the year of transition to the new system (2010), there were no relegations from any division below the highest, because the second-highest (old 2A, new 1B) was expanded by one team. International Championships: third format (from 2016 to 2022) In the event, and following a penaltyFrom September 2016, the European Nations Cup became the Rugby Europe International Championships, made up of five levels or divisions: Level 1 - Championship.
