Wikipedia:Good article reassessment (GAR) is a process primarily used to determine whether an article that is listed as good article (GA) still merits its good article status according to the good article criteria, and to delist it if not.

There are two types of reassessment: individual reassessment and community reassessment. Where possible, editors should conduct an individual reassessment, while community reassessment should be used if delisting is likely to be controversial.
