There are thirteen classifications for athletes with a physical disability (seven for standing and three for sitting) and three for athletes with visual impairments. When classifications are combined in competition due to an insufficient number of athletes in a class, a formula is used to "factor" athletes' times according to their classification status.

Visually impaired

• B1 - Totally blind participants with vision up to light perception / hand movement
• B2 - visual acuity of 2/60 and / or visual field of less than 5 degrees
• B3 - visual acuity above 2/60 to 6/60 and / or visual field of more than 5 degrees and less than 20 degrees

Standing

• LW1 double above-knee amputees or similar
• LW2 above knee amputee using outriggers and one ski
• LW3 double below-knee amputees/ CP5, CP6
• LW4 skiers with below knee amputation using prosthesis, two skis and poles
• LW5/7 skiers with both hands / arms amputated unable to use poles (LW5/7-1, LW5/7-2, LW 5/7-3)
• LW6/8 skiers with one hand / arm amputated using one pole (LW6/8 -1, LW6/8 -2)
• LW9 disability of one arm and one leg (Amputation, CP, Hemiplegic), (LW9/1, LW9/2)

Sitting

• LW10 mono skiers (high level of spinal cord injury), (LW10/1, LW10/2)
• LW11 mono skiers (thoracic spinal cord injury)
• LW12 mono skiers (paraplegia or double AK Amputees), (LW12/1, LW 12/2)
