For the thirteenth consecutive season, the tournament will be played in a double round-robin system. The team with the highest number of points at the end of the season will be declared champion. The bottom four teams will be relegated and will play in the Campeonato Brasileiro Série B in the 2016 season.
The Série A will serve as a qualifier to CONMEBOL's 2016 Copa Libertadores. The top-three teams in the standings will qualify to the Second Stage of the competition, while the fourth place in the standings will qualify to the First Stage.
Despite Criciúma's relegation in the previous championship, it will still mark the first time four clubs from Santa Catarina took part of the same Brasileirão, at least in its current format; last time it happened, in 1979, the championship had more than 90 teams.[3]
