The participating teams first played a conventional round-robin schedule with every team playing each opponent once "home" and once "away" (in actuality, the designation of home and away was purely arbitrary as the clubs did not have their own grounds) 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 in a home-and-away cycle of games. The top four teams competed for the championship. The bottom four clubs played for one direct relegation spot and one relegation play-off spot. Records earned in the First Round were taken over to the respective Second Rounds.

CE Benfica were relegated after last season due to finishing in 8th place. They were replaced by Segona Divisió runners-up FC Rànger's (the champions, Lusitanos B, were promotion ineligible).
