There were 32 member clubs in the Swiss Football Association (ASF/SFV), divided into two tiers of 16 teams each. The top tier was named Nationalliga A (NLA) and the second tier was named Nationalliga B (NLB).
The format in both divisions was that the teams played a double round-robin to decide their table positions. Each club playing every other club twice, for a total of 30 rounds. Two points were awarded for a win and one point was awarded for a draw.

The last two placed teams in the NLA were relegated to the NLB for the following season. The top two placed teams in the NLB would be promoted to the top tier. The last three teams in the NLB were relegated to next season's 1. Liga and would be replaced by the best three teams from this season's 1. Liga.[1]
