This was a parallel slalom competition. There were four members on each team (two males and two females), as well as two reserves. There were four races and the winner of each race scored a point for their team (a tied race awards one point per team). The first race was female against female, race two was male against male, race three was female against female and the last race was male against male. If, after four races, both teams had the same number of points, then the race times of each team's fastest man and woman would be added and the team with the best aggregate time won. If there were two non finishes in the same race, whoever progressed further would win the race.
Teams marked with asterisks won by faster cumulated time of the best male and the best female skier.
