1. divisjon is the second-highest professional football league in Norway. It features teams that compete for promotion to the top tier, known as Eliteserien. The league typically consists of 16 teams, and the season runs from spring to autumn. Teams in 1. divisjon play each other twice, once at home and once away, accumulating points to determine their standings. The top teams at the end of the season earn promotion, while the bottom teams may face relegation to lower divisions. This structure creates a competitive environment for clubs and players alike.
