Disciplines and classifications
Just like the age categories (U11, U13, U15…) or weight categories in judo for example (under 70 kg, heavy…), athletes with disabilities are divided into classes (when they are eligible) for competitions. The tens digits correspond to the disability families, with units indicating the class. In most cases, the larger the second number, the less severe the disability. Athletes will run, jump, and throw as part of the event.


How does it work?
T = Track
F = Field
A first number (the tens digit) for the disability family
1 = visual impairment
2 = intellectual disability
3 = brain injury (standing or sitting)
4 = short stature, amputee or similar
5 = wheelchair (running or throwing)
6 = lower limb disability / deaf and hard of hearing
A second number (the unit number) for the degree of disability
1 being the highest degree of disability, with 8 as the lowest. Athletes can be categorized within that range as well.
T/F 11-13 visually impaired athletes
T/F 20 athletes with intellectual disabilities
T/F 32-38 athletes with cerebral palsy or similar
T/F 40-41 athletes of small stature
T/F 42-47 amputees or similar athletes (except for lower limb amputees)
T/F 51-54 wheelchair athletes
T/F 51-57 wheelchair throwers
T/F 60 deaf and hard of hearing athletes
T/F 61-64 lower limb amputee athletes with aids
