If points were equal, the head-to-head records determined the winner (tie-breakers were also used in the past). If still equal, the goal difference and then goals scored became the deciding factors. As for Serie B, at the top end two, three or four clubs won promotion to Serie A, with the bottom Serie A clubs taking their places. At the lower end, three or four club were relegated to the Serie C, while teams from the Lega C joined in their place.
