The eight teams played against each other three times in a preliminary round, so that each club played 21 games. Then the league was divided into two groups of four: the best four teams played in the championship round for the title and international starting places, the four worst teams against relegation to the Segona Divisió . The points from the preliminary round were taken.
The four best-placed teams in the preliminary round played against each other for the championship in a double round, with all results from the preliminary round being transferred.
The four teams in places 5 to 8 of the preliminary round played against relegation in the second half of the season. Here, too, the results of the preliminary round were broadcast and a double round was held between the clubs. The last placed team was relegated directly, while the penultimate relegation games against the second from the Segona Divisió had to deny.
