Criteria
The American College of Rheumatology (ACR) supports criteria development projects in different topic areas related to rheumatic disease. Projects generally focus on classification, response, and remission criteria. The ACR has previously endorsed diagnostic criteria. The article below provides more detail on the differences between classification and diagnostic criteria, and why the ACR no longer endorses diagnostic criteria.
