Articles are labelled as:

• Featured articles
• Former featured articles
• A-class articles
• Good articles
• Delisted good articles
• B-class articles
• C-class articles
• Start-class articles
• Stub-class articles
• A full list is at Template:Icon/doc

These symbols are updated manually and may be out of date; you are encouraged to fix any errors you discover.

This list is tailored to the English-language Wikipedia. There is also a list of one thousand articles considered vital to Wikipedias of all languages.
