Para-swimming classification (original) (raw)
Para-swimming classification is a function-based classification system designed to allow for fair competition in disability swimming. The classes are prefixed with "S" for freestyle, butterfly and backstroke events, "SB" for breaststroke and "SM" for individual medley events. Swimmers with physical disabilities are divided into ten classes based on their degree of functional disability: S1, S2, S3, S4, S5, S6, S7, S8, S9 and S10. The lower number indicates a greater degree of impairment. Those with visual impairments are placed in three additional classes: S11, S12 and S13. One more class, S14, is reserved for swimmers with intellectual impairment. A final class, S15, is for athletes with hearing loss.
