 (FINA). The majority of rules for Paralympic swimming are the same as those for able-bodied competitions. Significant differences include the starting position and adaptations allowed for visually impaired swimmers. Competitors may start a race by standing on a platform and diving into the pool, as in able-bodied swimming, or by sitting on the platform and diving in, or they may start the race in the water. In events for the blind and visually impaired, people called "tappers" stand at the end of the pool and use a pole to tap the swimmers when they approach the wall, indicating when the swimmer should turn or end the race. Competitors in these events are required to wear blackened goggles, so that partially sighted swimmers compete at an even level with those who are totally blind.

Classification

Swimmers are classified according to the type and extent of their disability. The classification system allows swimmers to compete against others with a similar level of function.

Swimmers with physical disabilities are allocated a category between 1 and 10, with 1 corresponding to the most severe types of disability. Physical disabilities of Paralympic swimmers include single or multiple limb loss (through birth defects and/or amputation), cerebral palsy

, and disabilities which impair the use of joints.

Blind and visually impaired swimmers compete within separate categories, being allocated to categories 11, 12 or 13. Category 11 corresponds to totally blind swimmers, while competitors in category 13 have severe but not total visual impairment.

Swimmers with mental disabilities compete in category 14.

Numbers are combined with a letter prefix depending on the event type. An "S" prefix corresponds to freestyle

. Hence, a swimmer with severe physical disabilities competing in backstroke may compete in an S3 event, while a blind swimmer in the medley would compete in class SM11.
