A Guide to Classifications
Competitors are divided into three main categories: sit-ski (LW10-12), standing (LW1-9) and visually impaired (B1-3). Each category is then divided into classes based on functional ability according to the degree and type of disability.
Standing
Most competitors have a limb disability, such as an amputation below or above the knee or elbow. This category includes classes LW2, LW3, LW4, LW5/7, LW6/8, and LW9. Alpine skiing adds another class, LW1, and divides LW3 into 3/1 and 3/2.
Sit-Ski
This category includes athletes with lower extremity disabilities. In Alpine skiing, a mono-ski is used. In Nordic skiing, a sledge is used. A sledge is a specially designed chair attached to a pair of skis. Both Alpine and Nordic skiers are divided into LW10, LW11, and LW12. Alpine divides LW12 into 12/1 and 12/2.
Visually Impaired
A guide accompanies skiers competing in all events. The guide skis just ahead of the competitor and informs the competitor, either vocally or over a radio, of all corners, inclines, declines or other course alterations. In the biathlon events, an auditory system is used to guide the competitor toward the target. Competitors are divided into B1, B2 and B3. The guide is also awarded a medal in competition.
Scoring Within the Categories
Each class is assigned a percentage factor relative to the strongest class in the category. The competitor’s actual race time is adjusted (multiplied) by the percentage factor assigned to the class. The athlete in each category with the fastest adjusted time is the winner.
