The Swiss Football Association (ASF/SFV) had 28 members at this time.
The format in both divisions was that the teams played a double round-robin to decide their table positions.
In the NLA following this first qualification stage the division was divided in two, the top placed six teams then played a championship stage and the others in a relegation play-out.
In both groups each team took half of the points gained in the first stage, rounded up to complete units, as bonus with them.
In the following season the format was changed and both tiers would have 14 teams.
