There had been modifications to the
Swiss Football Association (ASF/SFV) in advance of this season and the format of the
Swiss Football League (Nationalliga) was changed accordingly. Until last season, there had been 32 member clubs in the association, divided into two tiers of 16 teams each. Now the number of clubs had now been increased to 36. As of this season there were 12 teams in the top-tier, the Nationalliga A (NLA). There were 24 teams in the second-tier, Nationalliga B (NLB), and these were divided into two groups, a West and an East group. The season was divided into two stages. In the first stage, the qualification phase, each team in each group played a double
round-robin to decide their table positions. The top eight teams from the qualification phase of the NLA would advance to the championship group. The last four teams would play against relegation, this against the top six teams in each group of the NLB who were also qualified to play in two promotion/relegation groups. Therefore, in the second stage the divisions were divided again. The top eight teams from the NLA qualification competed a double round-robin in the championship group to decide championship and over the qualification slots to next season's UEFA European competitions. The bottom four teams from the NLA qualification and the top six teams from both of the NLB qualification groups were drawn into two promotion/relegation groups (NLA/NLB). The top two teams in each of these groups would play the following season in the NLA, the others would contest in the NLB. There were also two relegation groups (NLB/1. Liga), each group with six teams. The last team in each NLB relegation group was to be relegated directly to the 1. Liga and the two fifth placed teams from each group played a play-out against relegation to decide the third relegation slot. ==Nationalliga A==
