With the Paris 2024 Paralympics well under way, we take a look at how the classification system works in para-sport – and how are athletes’ classifications defined?
Why are there different Paralympic classifications?
The idea behind classifications is to ensure that athletes compete against opponents of similar or equal impairment. Athletes are grouped together into ‘sport classes’ in an effort to create a level playing field.
The International Paralympic Committee says the classification system “has been put in place to minimise the impact of impairments on sport performance and to ensure the success of an athlete is determined by skill, fitness, power, endurance, tactical ability and mental focus”.
How are athletes’ classifications defined?
There are 10 broad categories of impairment that a Paralympic athlete can be put into – eight of them are a form of physical impairment, one for visual impairment and one for intellectual impairment.
Within these categories, there are then several sub-categories to increase the level of “fairness”. For example, there are eight sub-categories in athletics for competitors with cerebral palsy, ranging from the most to the least severe.
Classification systems differ by sport and are developed by the federations who govern the sport. Some Paralympic sports are only designed for athletes with one eligible impairment type – such as goalball which is only open to athletes with a vision impairment.
How does the classification system work?
Every athlete competing at the Paralympics will have been officially classified prior to the Games. They are assessed by technical officials known as “classifiers” and allocated a sport class in accordance with the degree and nature of their eligible impairment.
The “classifiers” have been appointed by the international governing body of each particular sport. Classifiers assess the athlete’s impairment and how it impacts on their ability to perform certain functions before assigning them to a particular class.
Classifying athletes is an ongoing process, which takes place at all major events, before and during competition. Thus, a competitor’s classification can change throughout their career as their level of impairment evolves.
Is there a medal for each classification?
Not necessarily. In some cases, athletes from different classifications will compete for the same medal because the sport’s governing body has decided that their particular impairments place them at around the same level of ability.
As the International Paralympic Committee explains: “Since different sports require different abilities, each sport logically requires its own classification system.
“For example, an impairment of the arms affects performance in a running event in athletics to a lesser extent than it affects performance in swimming.”
Is the percentage system always used to determine combined-class events?
No. Sometimes when there is not an event available for a particular classification, athletes are given the option of competing up a class with competitors who are less impaired.
For example, there is no T45 or T46 100m, so athletes in those categories are permitted to compete in the T47 race. For these events there is no percentage scoring system – the fastest run and furthest throw or jump wins.
