Para-alpine ski events held with skiers worldwide and skiers from specific countries include the Winter Paralympics, World championships World cups, Continental cups, National championships IPCAS competition, and IPCAS Para-Snowboard. Skiers from 39 different countries race in para-alpine skiing races. The sport is that one of eight given government by the International Paralympic Committee Sports Committee, with rules for para-alpine skiing put forth in the IPCAS Rules and Regulations. Special rules may be used for events like the Paralympic Games. One group of special rules was used in 1994 and were detailed in the IPC Handbook. This was used to make necessary IPC-sanctioned events like the Paralympic Games for many years. Competition rules for classes use rules put by or made an adjustment from rules made come into existence by the International Ski Federation (FIS). These rules were put at the 42nd International Ski Conference in 2000. The two rule groups worked in united ways with each other, with the FIS rules specifying the rules for alpine skiing and the IPC making ready adjustments for para-alpine skiing. The IPC Alpine Sports Assembly Executive Committee can decide if skiers have the necessary qualities to race in IPC sanctioned events without thought or attention to what the rules say. National Paralympic Committees can have their own rule for races they organize.
