Newly created articles are checked for obvious problems by members of the New pages patrol. These editors collaborate to identify articles which do not meet the criteria for inclusion and/or to tag them for any glaring issues that need attention. Article classification codes are assigned (on the article's talk page) based on an assessment of the article's quality. The assessment class codes may be updated by any contributor as the article is improved.
Typically, an article may begin with a Stub-class or Start-class code and is upgraded to C-class, then B-class as the article becomes more complete. Next, an article is submitted to the peer review process to receive ideas and feedback from other editors. Upon successful completion of the peer review, an article may then be nominated for GA-Class (Good Article) status.
