A total of 22 teams contested the league: 16 returning from the 2014–15 season, 4 promoted from Lega Pro, and 2 relegated from Serie A.
Vacancies created by the bankruptcy of Serie A-relegated Parma and the demotion of Catania to Lega Pro due to match fixing allowed Brescia to remain in the league despite being relegated.
Furthermore, Ascoli was promoted into the championship after finishing second in Lega Pro Group B, second after Teramo before being stripped of the title for the match-fixing scandal.
The green card was not given during the game, as it would alter sport rules, but awarded after the match to a player or coach who exhibited fair play by the referee.
The higher placed team played the second leg of the promotion playoff at home.
