The parameters defined by the World Para Alpine Skiing Federation (World Para Alpine Skiing) are used for the definition of the Categories.

Sport Classes LW1-9: Standing Skiers
Skiers with leg impairments:
Sport Class LW1: This sport class is allocated to athletes with an impairment that strongly affects both legs, for example an above knee amputation of both legs or significant muscle weakness in both legs.
Sport Class LW2: Skiers have a significant impairment in one leg. Some skiers, for example, have an impaired leg from birth. You will see them ski with one ski only.
Sport Class LW3: This sport class is for athletes who have a moderate impairment in both legs. They will ski with two skis and prosthesis. Some LW 3 skiers have mild coordination problems or muscle weakness in both legs, or a below knee amputation in both legs.
Sport Class LW4: Similar to skiers in Sport Class LW 2, LW 4 skiers have an impairment in one leg only, but with less Activity Limitation. A typical example is a below knee amputation in one leg. They will use two skis during the race.

Skiers with arm impairments:
Sport Class LW5/7: Athletes in this Sport Class ski with an impairment in both arms. Some athletes have amputations and others have limited muscle power or coordination problems. They will race down the slopes without ski poles.
Sport Class LW6/8: Skiers have an impairment in one arm. Skiers will compete with one ski pole only.

Skiers with combined arm and leg impairments:
Sport Class LW9: Skiers in this Sport Class have an impairment that affects arms and legs. Some skiers in this class have coordination problems, such as spasticity or some loss of control over one side of their body. Depending on their abilities, they will ski with one or two skis and one or two poles

Sport Classes LW10-12:Sit Skiers
All sit-skiers have an impairment affecting their legs. They are allocated different sport classes depending on their sitting balance, which is very important for acceleration and balancing during the races.
Sport Class LW10: Skiers in this Sport Class have no or minimal trunk stability, for example due to spinal cord injuries or spina bifida. They therefore rely mainly on their arms to manoeuvre the sit-ski.
Sport Class LW11: Skiers have good abilities in their upper trunk, but very limited control in their lower trunk and hips, as it would be the case for skiers with lower spinal cord injuries.
Sport Class LW12: This sport class includes skiers with normal or only slightly decreased trunk function and leg impairments. Skiers with leg impairments in Sport Classes LW 1-4 often also fit this sport class, so that they can choose if they want to ski sitting or standing in the beginning of their career.

Sport Classes B1-3: Skiers with vision impairment
Sport Class B1: Skiers in this sport class are either blind or have very low visual acuity. By way of explanation, their level of visual acuity is such that the athlete cannot recognise the letter “E” (15x15cm in size) from a distance of 25cm. During the race they are required to wear eyeshades.
Sport Class B2: This sport class profile includes athletes with a higher visual acuity than athletes competing in the B1 class, but they are unable to recognise the letter “E” from a distance of 4m. Moreover, athletes with a visual field of less than 10 degrees diameter are eligible for this sport class.
Sport Class B3: The B3 sport class profile describes the least severe vision impairment eligible for Para alpine skiing. Eligible athletes either have a restricted visual field of less than 40 degrees diameter or a low visual acuity.
In Para alpine skiing, you will see athletes with vision impairment skiing with a guide. The guide skis in front of the athlete and verbally gives directions to the athlete. The guide is considered, for all purposes, an athlete.

In the first edition of the giant slalom race of para alpine skiers (2021), the starting numbers will be drawn from all registered participants. In the following years, the starting order for each category is drawn after the participants have been divided into the following starting groups:
1st group: competitors placed 1st to 15th in one of the two preceding sessions of the Ski Meeting
2nd group: competitors placed 16th to 30th in one of the two preceding sessions of the Ski Meeting
3rd group: competitors placed 31st to 45th in one of the two preceding sessions of the Ski Meeting
4th group: competitors placed 46th to 60th in one of the two preceding sessions of the Ski Meeting
5th group: all other competitors.

Women's categories (B1F - B2F - B3F - LW1F - LW2F - LW3F - LW4F - LW5F - LW6F - LW7F - LW8F - LW9 - LW10F - LW11F - LW12F) start first.
All grouped in the PAF category.

Then start the men's categories (B1M - B2M - B3M - LW1M - LW2M - LW3M - LW4M - LW5M - LW6M - LW7M - LW8M – LW9M - LW10M - LW11M - LW12M).
All grouped in the PAM category.

Athletes who arrive late at the start will start last in their category.

There are no restrictions on the choice of material. All types of skis can be used.
