The UEFA Euro 2016 Referee Preparatory Workshop will take place in Enghien-Les-Bains, near Paris, from 18 to 21 April 2016. The workshop will involve 112 match officials in total. The referee teams will train together, undertake fitness tests and review the application of technical instructions for the final tournament, which takes place in France from 10 June to 10 July. Subsequently, 94 match officials will return to France on 6 June for the tournament itself. Each referee team comprises six match officials: one main referee, two additional assistant referees, and two assistant referees. A third assistant referee has also been named as a reserve for each team, and will remain on standby until the start of the tournament to take the place of a colleague if necessary. The majority of assistants and additional assistants come from the same country as the referee.
The workshop will be held at the Hôtel du Lac, 89 rue du Général de Gaulle, 95880 Enghien-les-Bains, which will serve as the base for the referees’ teams during UEFA Euro 2016. A training session will be open to the media for 15 minutes on the morning of Wednesday 20 April, and takes place at the Centre Départemental de Formation et d’Animation Sportives (CDFAS), 64 rue des Bouquinvilles, 95600 Eaubonne. A press conference will then be held after the open training session, at 11.30CET at the Hôtel du Lac, in the presence of some of the referees and members of the UEFA Referees Committee, including UEFA's Chief Refereeing Officer Pierluigi Collina. After the press conference, media representatives will have the possibility for one-to-one interviews with the referees.
