A featured article exemplifies our very best work and is distinguished by professional standards of writing, presentation, and sourcing. In addition to meeting the requirements for all Wikipedia articles, it has the following attributes.

1. It is—
   • (a) well-written: its prose is engaging, even brilliant, and of a professional standard;
   • (b) comprehensive: it neglects no major facts or details and places the subject in context;
   • (c) well-researched: it is a thorough and representative survey of the relevant literature on the topic. Claims are verifiable against high-quality reliable sources and are supported with citations; this requires a "References" section that lists these sources, complemented by inline citations where appropriate;
   • (d) neutral: it presents views fairly and without bias; and
   • (e) 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.
2. It follows the style guidelines, including the provision of—
   • (a) a lead: a concise lead section that summarizes the topic and prepares the reader for the detail in the subsequent sections;
   • (b) appropriate structure: a system of hierarchical section headings and a substantial but not overwhelming table of contents; and
   • (c) 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.
3. Images. It has images that follow the image use policy and other media where appropriate, with succinct captions, brief and useful alt text when feasible, and acceptable copyright status. Non-free images or media must satisfy the criteria for inclusion of non-free content and be labeled accordingly.
4. Length. It stays focused on the main topic without going into unnecessary detail (see summary style).

1. Prose. It features professional standards of writing.
2. Lead. It has an engaging lead that introduces the subject and defines the scope and inclusion criteria.
3. Comprehensiveness.
   • (a) It comprehensively covers the defined scope, providing at least all of the major items and, where practical, a complete set of items; where appropriate, it has annotations that provide useful and appropriate information about the items.
   • (b) In length and/or topic, it meets all of the requirements for stand-alone lists; it is not a content fork, does not largely recreate material from another article, and could not reasonably be included as part of a related article.
4. Structure. It is easy to navigate through and includes, where helpful, section headings and table sort facilities.
5. Style. It complies with the Manual of Style and its supplementary pages.
   • (a) Visual appeal. It makes suitable use of text layout, formatting, tables, and colour; and it has a minimal proportion of red links.
   • (b) Media files. It has images and other media, if appropriate to the topic, that follow Wikipedia's usage policies, with succinct captions and alternative (alt) text if necessary. Non-free images and other media satisfy the criteria for the inclusion of non-free content and are labeled accordingly.
6. Stability. It is not the subject of ongoing edit wars and its content does not change significantly from day to day, except in response to the featured list process.

Provides a well-written, clear and complete description of the topic, as described in Wikipedia:How to write a great article. It should be of a length suitable for the subject, appropriately structured, and be well referenced by a broad array of reliable sources. It should be well illustrated, with no copyright problems. Only minor style issues and other details need to be addressed before submission as a featured article candidate. See the A-Class assessment departments of some of the larger WikiProjects (e.g. WikiProject Military history, WikiProject Films).

1. Well-written:

   (a) the prose is clear and the spelling and grammar are correct; and

   (b) it complies with the manual of style guidelines for lead sections, layout, jargon, words to avoid, fiction, and list incorporation.

2. Factually accurate and verifiable:

   (a) it provides references to all sources of information in the section(s) dedicated to the attribution of these sources according to the guide to layout;

   (b) it provides in-line citations from reliable sources for direct quotations, statistics, published opinion, counter-intuitive or controversial statements that are challenged or likely to be challenged, and contentious material relating to living persons—science-based articles should follow the scientific citation guidelines; and

   (c) it contains no original research.

3. Broad in its coverage:

   (a) it addresses the main aspects of the topic; and

   (b) it stays focused on the topic without going into unnecessary detail (see summary style).

4. Neutral: it represents viewpoints fairly and without bias.
5. Stable: it does not change significantly from day-to-day because of an ongoing edit war or content dispute.
6. Illustrated, if possible, by images:

   (a) images are tagged with their copyright status, and valid fair use rationales are provided for non-free content; and

   (b) images are relevant to the topic, and have suitable captions.

1. The article is suitably referenced, with inline citations where necessary. It has reliable sources, and any important or controversial material which is likely to be challenged is cited. The use of citation templates such as {{cite web}} is not required, but the use of <ref></ref> tags is encouraged.
2. The article reasonably covers the topic, and does not contain obvious omissions or inaccuracies. It contains a large proportion of the material necessary for an A-Class article, although some sections may need expansion, and some less important topics may be missing.
3. The article has a defined structure. Content should be organized into groups of related material, including a lead section and all the sections that can reasonably be included in an article of its kind.
4. The article is reasonably well-written. The prose contains no major grammatical errors and flows sensibly, but it certainly need not be "brilliant". The Manual of Style need not be followed rigorously.
5. The article contains supporting materials where appropriate. Illustrations are encouraged, though not required. Diagrams and an infobox etc. should be included where they are relevant and useful to the content.
