A good article (GA) is an article that meets a core set of editorial standards, the good article criteria, passing through the good article nomination process successfully. They are well-written, contain factually accurate and verifiable information, are broad in coverage, neutral in point of view, stable, and illustrated, where possible, by relevant images with suitable copyright licenses. Good articles do not have to be as comprehensive as featured articles (FA), but they should not omit any major facets of the topic: a comparison of the criteria for good and featured articles describes further differences.
Currently, out of the 6,664,528 articles on Wikipedia, 37,824 are categorized as good articles (about 1 in 177), most of which are listed below. An additional 6,278 are listed as featured articles (about 1 in 1,070) and 4,123 as featured lists (about 1 in 1,620). Because articles are only included in one category, a good article that has been promoted to featured status is removed from the good articles category. Adding good and featured articles and lists together gives a total of 48,225 articles (about 1 in 139). A small plus sign inside a circle () in the top-right corner of an article's page indicates that the article is good.
The process for designating an article as a good article is intentionally straightforward. Any editor who believes that an article they have significantly contributed to meets the good article criteria may nominate the article for an impartial reviewer to assess. Another editor may review the article after selecting it from a queue of good article nominations then evaluating it against the good article criteria. If it is accepted by the reviewer, the nominated article is added to the list of good articles below. Anyone may nominate or review an article by following the instructions. Similarly, anyone who believes that an article no longer meets the good article criteria may propose to delist it by following the instructions for reassessment.
