ACR score is a scale to measure change in rheumatoid arthritis symptoms.[1][citation needed] It is named after the American College of Rheumatology. The ACR score is more often used in clinical trials than in doctor patient-relationships, as it allows a 'common standard' between researchers.

Different degrees of improvement are referred to as ACR20, ACR50, ACR70. ACR20 was initially proposed with ACR scoring, measuring a 20% improvement on a scale of 28 intervals. ACR50 and ACR70 were later proposed, corresponding to 50% and 70% improvements.[2]

The Rheumatoid Arthritis Severity Scale (RASS) is based on sections of the ACR scoring system.[3]

The 2010 ACR / EULAR Rheumatoid Arthritis Classification Criteria, which includes anti-CCP testing, has been developed to focus on early disease, and on features that are associated with persistent or erosive disease.[4]
