Competition format
The participating teams first played a conventional round-robin schedule with every team playing each opponent once home and once away for a total of 14 games. The league was then split up in two groups of four teams with each of them playing teams within their group a home-and-away cycle of games. The top four teams competed for the championship. The bottom four clubs played out one direct relegation spot and one relegation play-off spot. Records earned in the first round were taken over to the respective second rounds.
Further, UE Engordany and Segona Divisió runners-up UE Extremenya played a two-legged relegation play-off. Engordany kept their spot in Primera Divisió by winning 5–3 on aggregate.
