A factoring system was made to come into existence for para-alpine skiing for three general groups: being seated, standing, and not seeing. Each group races against only people in the same group. A skier can finish in the top three for only seated, standing, or not seeing. People from one group do not race against other skiers in a different group. Inside each group, there is a wide range of ability to move and medical problems or see. Skiers are classed inside one of the three groups. The factoring system works by having a number for each class, where the results are worked out by increasing in number the look time by the factored number. The coming out number is used to decide on the one who came out best in events where the cause system is used. This means the quicker skier down a hill may not be the first event in events where the factor system is used. This means the faster skier down a hill may not be the winner of an event. The factor system is used at Alpine Cup, North American Races, European Cup, World Cup races, World Championships, and the Winter Paralympics.
