The UEFA European Under-17 Championship consists of three distinct stages: the qualifying round, the elite round and the final tournament. The format changed for 2014/15 with the expansion of the final tournament from eight to 16 teams.
The qualifying round, played in autumn, is made up of 13 groups of four countries playing in one-venue mini-tournaments. The top two from each pool progress alongside the four third-placed sides with the best record against the leading pair in their groups.
In the elite round, held in early spring, those 30 qualifiers plus the top two seeds – given a bye this far – compete in eight mini-tournament groups of four. The group winners and seven runners-up with the best record against the teams first and third in their section advance to the finals to join the hosts.
In the final tournament the contenders are split into four groups of four, with the front two from each proceeding to the knockout phase.
Further details, including the criteria for separating sides that finish level on points in a group, or after 80 minutes in a match, can be found in the official competition regulations.
How does the tournament work?
Fifteen countries booked their places at the finals, which run from 3 to 19 May, alongside hosts Croatia by negotiating the qualifying and elite rounds.
These 16 teams will compete in four groups of four, with the top two in each section progressing to the quarter-finals. Games are 80 minutes in duration and knockout fixtures level at full time will be decided by a penalty shoot-out.
The tournament will also act as the European qualifiers for UEFA's five berths in the 2017 FIFA U-17 World Cup in India, from 6 to 28 October.
