Three classifications of juvenile chronic arthritis are used: the classification of juvenile rheumatoid arthritis of the American College of Rheumatology (ACR), the classification of juvenile chronic arthritis of the European League against rheumatism (EULAR), the classification of juvenile idiopathic arthritis of the International League of Rheumatological Associations (ILAR).

The classification of ILAR needs to be improved, as 20% of children with arthritis either do not meet the criteria of any category, or meet the criteria of more than one category. Every physician who observes children with arthritis should understand that juvenile rheumatoid arthritis is a heterogeneous disease that requires early diagnosis and the appointment of adequate therapy even before the development of joint destruction and disability of the child.
