Each athletics event is given a code, made up of one letter and two numbers, which is called a classification. It tells you more about the type of disability the athletes in that event have.

• The first letter will either be T or F: T is for track (running and jumping events) and F is for field (throwing events).
• The first number, from 1 to 5, tells you the impairment type: 1. Visual impairment 2. Intellectual impairment 3. Co-ordination impairment 4. Limb deficiencies and short stature 5. Impaired muscle power or range of movement.
• The second number ranges from 1 to 8 and designates the level of impairment, with 1 being the most impaired.
