Swimming classification

To ensure competition is fair and equal, all Paralympic sports have a system in place which ensures that winning is determined by skill, fitness, power, endurance, tactical ability and mental focus, the same factors that account for success in sport for able bodied athletes.

This process is called classification and its purpose is to minimise the impact of impairment on the activity (sport discipline). Having an impairment thus is not sufficient. The impact of that impairment on the sport must be proved. In World Para Swimming, athletes are grouped by the degree of activity limitation resulting from an impairment. These groups are called ‘sport classes’. The process of classification determines which athletes are eligible to compete in World Para Swimming and how athletes are grouped together for competition.

Classification is sport-specific because an impairment affects the ability to perform in different sports to a different extent. As a consequence, an athlete may meet the criteria in one sport, but may not meet the criteria in another sport.

World Para Swimming caters for three impairment groups - physical, visual and intellectual.

Sport Classes

The sport class names in swimming consist of a prefix “S” or “SB” and a number. The prefixes stand for the strokes and the number indicates the sport classes.

The prefixes stand for:

• S: freestyle, butterfly and backstroke events

• SB: breaststroke

• SM: individual medley. The prefix “SM” is given to athletes competing in individual medley events. It is not a sports class, but an entry index and calculated as (3xS + SB)/4; for classes S1-4 who have a 3-discipline medley, the formula is (2S + SB)/3).

Sport Classes S1-S10 / SB1 – SB9 / SM1- SM10 physical impairment

There are ten different sport classes for athletes with physical impairment, numbered 1-10. A lower number indicates a more severe activity limitation than a higher number.

Athletes with different impairments compete against each other, because sport classes are allocated based on the impact the impairment has on swimming, rather than on the impairment itself.

To evaluate the impact of impairments on swimming, classifiers assess all functional body structures using a point system and ask the athlete to complete a water assessment. The total number of points then determines the athlete’s S and SB sport classes. Due to the different demands of S and SB events, swimmers are often allocated different S and SB sport classes. The SM sport class is calculated from the S and SB sport class.

Sport Classes S/SB11-13 visual impairment

Athletes with a visual impairment compete in three sport classes from S/SB11 to S/SB13.

S/SB11: These athletes have a very low visual acuity and/ or no light perception.

S/SB12: Athletes have a higher visual acuity than athletes competing in the S/SB11 sport class and/ or a visual field of less than 5 degrees radius.

S/SB13: Athletes have the least severe visual impairment eligible for Paralympic sport. They have the highest visual acuity and/or a visual field of less than 20 degrees radius.

In order to ensure a fair competition athletes in the S/SB11 sport class are required to wear blackened goggles. To ensure safety all S/SB11 swimmers must use a tapper, swimmers in the S/SB12 and S/SB13 sport classes may choose whether or not they wish to use one.

Sport Classes S/SB14 intellectual impairment

S14 swimmers have an intellectual impairment, which typically leads to the athletes having difficulties with regards to pattern recognition, sequencing, and memory, or having a slower reaction time, which impact on sport performance in general. Moreover, S14 swimmers show a higher number of strokes relative to their speed than able-bodied elite swimmers.
