The following system is used by the Wikipedia community to assess the quality of an article on a particular topic. The system is based on a letter scheme which reflects principally how factually complete the article is, though language quality and layout are also factors.

The quality assessments are mainly performed by Wikipedia editors, who tag talk pages of articles. These tags are then collected by a bot, which generates output such as a log and statistics. For more information, see Using the bot. (Note that when more than one WikiProject has rated an article, the bot will take the best rating as the rating of the overall article.) The WP:1.0 team is planning to set things up to use a second bot to select articles, based on the assessments performed by WikiProjects.

Two levels, GA (Good Article) and FA (Featured Article), are assessments made by independent editors, rather than by WikiProjects. GAs are generally reviewed by a single editor, and FA by several editors. Candidates are nominated by listing them at WP:Good article nominations and WP:Featured article candidates. Judgments are made according to the criteria at WP:Good article criteria and WP:Featured article criteria, and the results are listed at WP:Good articles and WP:Featured articles.

It is vital that editors not take these assessments of their contributions personally. It is understood that we each have our own opinions of the priorities of the objective criteria for a perfect article. Generally an active project will develop a consensus, though be aware that different projects may use their own variation of the criteria more tuned for the subject area, such as this. More active WikiProjects have an assessment team. If you contribute a lot of content to an article you may request an independent assessment.

At present this assessment system is in use in the Wikipedia 1.0 project, and in several hundred WikiProjects on the English Wikipedia. As of November 2022, over seven million articles have been assessed. Several other languages are also using this assessment system or a derivative thereof.

Grades

WikiProject content quality grading scheme

Class	Criteria	Reader's experience	Editing suggestions	Example
FA	The article has attained featured article status by passing an in-depth examination by impartial reviewers from WP:Featured article candidates. More detailed criteria The article meets the featured article criteria: A featured article exemplifies our very best work and is distinguished by professional standards of writing, presentation, and sourcing. In addition to meeting the policies regarding content for all Wikipedia articles, it has the following attributes. It is— well-written: its prose is engaging, even brilliant, and of a professional standard; comprehensive: it neglects no major facts or details and places the subject in context; well-researched: it is a thorough and representative survey of the relevant literature. Claims are verifiable against high-quality reliable sources and are supported by inline citations where appropriate; neutral: it presents views fairly and without bias; and stable: it is not subject to ongoing edit wars and its content does not change significantly from day to day, except in response to the featured article process. It follows the style guidelines, including the provision of— a lead: a concise lead section that summarizes the topic and prepares the reader for the detail in the subsequent sections; appropriate structure: a system of hierarchical section headings and a substantial but not overwhelming table of contents; and consistent citations: where required by criterion 1c, consistently formatted inline citations using either footnotes (<ref>Smith 2007, p. 1.</ref>) or Harvard referencing (Smith 2007, p. 1)—see citing sources for suggestions on formatting references; for articles with footnotes, the meta:cite format is recommended. The use of citation templates is not required. Media. It has images and other media where appropriate, with succinct captions, and acceptable copyright status. Images included follow the image use policy. Non-free images or media must satisfy the criteria for inclusion of non-free content and be labeled accordingly. Length. It stays focused on the main topic without going into unnecessary detail and uses summary style.	Professional, outstanding, and thorough; a definitive source for encyclopedic information.	No further content additions should be necessary unless new information becomes available; further improvements to the prose quality are often possible.	Cleopatra (as of June 2018)
FL	The article has attained featured list status by passing an in-depth examination by impartial reviewers from WP:Featured list candidates. More detailed criteria The article meets the featured list criteria:විකිපීඩියා:Featured list criteria	Professional standard; it comprehensively covers the defined scope, usually providing a complete set of items, and has annotations that provide useful and appropriate information about those items.	No further content additions should be necessary unless new information becomes available; further improvements to the prose quality are often possible.	List of dates predicted for apocalyptic events (as of May 2018)
A	The article is well organized and essentially complete, having been examined by impartial reviewers from a WikiProject or elsewhere. Good article status is not a requirement for A-Class. More detailed criteria The article meets the A-Class criteria: විකිපීඩියා:Content assessment/A-Class criteria	Very useful to readers. A fairly complete treatment of the subject. A non-expert in the subject would typically find nothing wanting.	Expert knowledge may be needed to tweak the article, and style problems may need solving. WP:Peer review may help.	Battle of Nam River (as of June 2014)
GA	The article meets all of the good article criteria, and has been examined by one or more impartial reviewers from WP:Good article nominations. More detailed criteria විකිපීඩියා:Good article criteria	Useful to nearly all readers, with no obvious problems; approaching (though not necessarily equalling) the quality of a professional publication.	Some editing by subject and style experts is helpful; comparison with an existing featured article on a similar topic may highlight areas where content is weak or missing.	Discovery of the neutron (as of April 2019)
B	The article meets all of the B-Class criteria. It is mostly complete and does not have major problems, but requires some further work to reach good article standards. More detailed criteria විකිපීඩියා:Content assessment/B-Class criteria	Readers are not left wanting, although the content may not be complete enough to satisfy a serious student or researcher.	A few aspects of content and style need to be addressed. Expert knowledge may be needed. The inclusion of supporting materials should be considered if practical, and the article checked for general compliance with the Manual of Style and related style guidelines.	Psychology (as of January 2024)
C	The article is substantial but is still missing important content or contains irrelevant material. The article should have some references to reliable sources, but may still have significant problems or require substantial cleanup. More detailed criteria The article cites more than one reliable source and is better developed in style, structure, and quality than Start-Class, but it fails one or more of the criteria for B-Class. It may have some gaps or missing elements, or need editing for clarity, balance, or flow.	Useful to a casual reader, but would not provide a complete picture for even a moderately detailed study.	Considerable editing is needed to close gaps in content and solve cleanup problems.	Wing (as of June 2018)
Start	An article that is developing but still quite incomplete. It may or may not cite adequate reliable sources. More detailed criteria The article has a meaningful amount of good content, but it is still weak in many areas. The article has one or more of the following: A useful picture or graphic Multiple links that help explain or illustrate the topic A subheading that fully treats an element of the topic Multiple subheadings that indicate material that could be added to complete the article	Provides some meaningful content, but most readers will need more.	Providing references to reliable sources should come first; the article also needs substantial improvement in content and organisation. Also improve the grammar, spelling, writing style and improve the jargon use.	Ball (as of September 2014)
Stub	A very basic description of the topic. Meets none of the Start-Class criteria.	Provides very little meaningful content; may be little more than a dictionary definition. Readers probably see insufficiently developed features of the topic and may not see how the features of the topic are significant.	Any editing or additional material can be helpful. The provision of meaningful content should be a priority. The best solution for a Stub-class Article to step up to a Start-class Article is to add in referenced reasons of why the topic is significant.	Lineage (anthropology) (as of December 2014)
List	Meets the criteria of a stand-alone list or set index article, which is an article that contains primarily a list, usually consisting of links to articles in a particular subject area.	There is no set format for a list, but its organization should be logical and useful to the reader.	Lists should be lists of live links to Wikipedia articles, appropriately named and organized.	List of literary movements

Note: Some WikiProjects omit some of the standard classes, most often A-class, especially when they lack an assessment team.

Non-standard grades

කෙටි මග

WP:NONSTANDARDCLASS

Some WikiProjects use other assessments for mainspace content that do not fit into the above scale:

Other WikiProject assessments
Label	Criteria	Reader's experience	Editing suggestions	Example
සැකිල්ල:Current-Class	A topic where details are subject to change often. The article covers an event or topic that is currently ongoing, such as a natural disaster or sports season.	Amount of meaningful content varies over time as the projected event goes on.	Material added might quickly become obsolete.	2019–20 South-West Indian Ocean cyclone season (as of August 2019)
සැකිල්ල:Future-Class	A topic where details are subject to change often. The article covers a future topic, e.g. a forthcoming election or album release, and article content may change as new information arises.	Amount of meaningful content varies over time as the projected event draws near.	Material added might be speculative and should be carefully sourced.	Next United Kingdom general election (as of October 2019)
සැකිල්ල:SL-Class	A list article that would otherwise be regarded as a stub. Used only by a few WikiProjects.	May be incomplete or provide little context.	Any editing or additional material can be helpful. The provision of meaningful content should be a priority.	Pink flowers (as of July 2019)
සැකිල්ල:SIA-Class	Any set index article (SIA) page falls under this class. These are list articles about a set of items of a specific type that also share the same (or similar) name.	The page lists related items of the same name.	An SIA need not follow the formatting rules for disambiguation pages	USS Yorktown (as of May 2018)
සැකිල්ල:Disambig-Class	Any disambiguation page falls under this class.	The page directs the reader to other pages of the same title.	Additions should be made as new articles of that name are created.	Jackson (as of August 2019)
සැකිල්ල:Redirect-Class	Any redirect falls under this class.	The page does not display any article content and redirects to a related topic.	Ensure that the redirect is appropriately categorised.	American breakfast (as of October 2016)
සැකිල්ල:Merge-Class	Any redirect that is the result of a page merge and has non-trivial history. Used only by a few WikiProjects.	The page does not display any article content and redirects to a related topic.	Tag the redirect page with {{R from merge}}	Tamara (Dungeons & Dragons) (as of August 2018)
සැකිල්ල:Needed-Class	May be used to identify redirects that could be expanded into articles, or articles with content that could be split off to form a new page.	Content may not yet exist for the desired topic.	Editors are encouraged to be bold when updating the encyclopedia.	Free City of Mainz (as of March 2018)
සැකිල්ල:NA-Class	A page that does not fit into any other category. Used as a "catch-all" by all WikiProjects.	Depends on the type of page.	Depends on the type of page.	N/A

See also Wikipedia:WikiProject Military history/Assessment which utilises a parallel scheme of "CL-Class", "BL-Class" and "AL-Class" for list articles.

Non-mainspace content

Further grades are commonly used by WikiProjects to categorise relevant pages in other namespaces. The precise application of these grades may vary depending on their usage by individual WikiProjects.

Non-mainspace assessments
Label	Criteria	Example
සැකිල්ල:Category-Class	Any category falls under this class.	Category:George Orwell
සැකිල්ල:Draft-Class	Any draft falls under this class. These are typically found in the Draft namespace, but may also be in the User namespace.	Draft:Example
සැකිල්ල:File-Class	Any file falls under this class; may also include timed text pages.	File:Flag of Australia.svg
සැකිල්ල:FM-Class	Any file which has attained featured picture or featured sound status.	File:Felis silvestris silvestris.jpg
සැකිල්ල:Portal-Class	Any portal falls under this class.	Portal:Biography
සැකිල්ල:Project-Class	Any project page falls under this class; may also include help pages.	Wikipedia:WikiProject Japan
සැකිල්ල:Template-Class	Any template falls under this class; may also include modules or userboxes.	Template:Magnapop
සැකිල්ල:User-Class	Any user page falls under this class.	User:Legoktm/afcnew.js

Note that some WikiProjects deal exclusively with non-mainspace content and may use their own customised assessment schemes tailored to a specific purpose: see Wikipedia:WikiProject Portals/Assessment for one such example.

Evolution of an article – an example

This clickable imagemap, using the article "Atom" as an example, demonstrates the typical profile for an article's development through the levels. Hold the mouse over a number to see key events, and click on a number to see that version of the article. Please note that until 2008, a C-class rating did not exist on the project, and as such this grading is retroactive. Also, in 2006 references were much less used, and inline references were quite rare; a barely-B-Class article today would typically have many more references than this article did in late 2006.

Importance assessment

There is a separate scale for rating articles for importance or priority, which is unrelated to the quality scale outlined here. Unlike the quality scale, the priority scale varies based on the project scope. See also the template {{importance scheme}}.

Statistics

The WP 1.0 bot tracks assessment data (article quality and importance data for individual WikiProjects) assigned via talk page banners. If you would like to add a new WikiProject to the bot's list, please read the instructions at Wikipedia:Version 1.0 Editorial Team/Using the bot.

The global summary table below is computed by taking the highest quality and importance rating for each assessed article in the main namespace.

FAQ

Purpose

What is the purpose of article assessments?: The assessment system allows a WikiProject to monitor the quality of articles in its subject areas, and to prioritize work on these articles. The ratings are also used by the Wikipedia 1.0 program to prepare for static releases of Wikipedia content.
Are these ratings official?: Not really; these ratings are meant primarily for the internal use of the project, and usually do not imply any official standing within Wikipedia as a whole.

Assessing articles

Who can assess articles?: In general, anyone can add or change an article's rating. However, assessing an article as "A-Class" generally requires the agreement of at least two editors, and the "GA" and "FA" labels should only be used on articles that have been reviewed and are currently designated as good articles or featured articles, respectively. Individual WikiProjects may also have more formal procedures for rating an article, and please note that the WikiProject bears ultimate responsibility for resolving disputes.
How do I assess an article?: Consult the quality scale above; once you have chosen the level that seems to be closest to the article, set the class parameter in the WikiProject banner template to the level's name (omitting "Class" from the end). For example, to rate an article as "B-Class", use |class=B in the banner. Again, the "FA" and "GA" labels should not be added to articles unless they are currently designated as such. Tools in the See also section can help with the assessment process.
How can I ask for an article to be assessed?: To have an independent editor review an article, post a request at Wikipedia:WikiProject Wikipedia/Assessment#Requesting an assessment.

Common concerns

Someone put a project banner template on an article, but it's not really within the WikiProject's scope. What should I do?: Because of the large number of articles we deal with, we occasionally make mistakes and add tags to articles that shouldn't have them. If you notice one, feel free to remove the tag, and optionally leave a note on the article's talk page (or directly with the person who tagged the article). See Wikipedia:WikiProject Council/Guide#Article tagging for more information.
What if I don't agree with a rating?: Feel free to change it—within reason—if you think a different rating is justified; in the case of major disputes, the WikiProject as a whole can discuss the issue and come to a consensus as to the best rating.
Aren't the ratings subjective?: Yes, they are somewhat subjective, but it's the best system we've been able to devise. If you have a better idea, please don't hesitate to let us know!
Why didn't the reviewer leave any comments?: Due to the volume of articles that need to be assessed, we are unable to leave detailed comments in most cases. If you have particular questions, you might ask the person who assessed the article; they will usually be happy to provide you with their reasoning. Wikipedia:Peer review is the process designed to provide detailed comments.
