Wikipedia:WikiProject American football/Assessment

A featured article exemplifies Wikipedia's 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.

1. It is:
   1. well-written: its prose is engaging and of a professional standard;
   2. comprehensive: it neglects no major facts or details and places the subject in context;
   3. 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;
   4. neutral: it presents views fairly and without bias;
   5. 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; and
   6. compliant with Wikipedia's copyright policy and free of plagiarism or too-close paraphrasing.
2. It follows the style guidelines, including the provision of:
   1. a lead: a concise lead section that summarizes the topic and prepares the reader for the detail in the subsequent sections;
   2. appropriate structure: a substantial but not overwhelming system of hierarchical section headings; and
   3. consistent citations: where required by criterion 1c, consistently formatted inline citations using footnotes—see citing sources for suggestions on formatting references. Citation templates are not required.
3. Media. It has images and other media, where appropriate, with succinct captions and acceptable copyright status. Images follow the image use policy. 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 and uses summary style where appropriate.

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) statements are sourced where they appear, and they provide inline citations if they contain any of the four kinds of material absolutely required to have citations.
   • (c) In length and/or topic, it meets all of the requirements for stand-alone lists; does not violate the content-forking guideline, does not largely duplicate material from another article, and could not reasonably be included as part of a related article.
4. Structure. It is easy to navigate 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 a minimal proportion of items are redlinked.
   • (b) Media files. It has images and other media, if appropriate to the topic, that follow Wikipedia's usage policies, with succinct captions. Non-free images and other media satisfy the criteria for the inclusion of non-free content and are labeled accordingly.
   • (c) Accessibility. It uses proper formating to be accessible to all readers. Bulleted and unbulleted lists and tables are structured correctly. Visual media, if included, utilize alternative (alt) text.
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.

1. Is of a high technical standard.
   • It has good contrast, accurate exposure and neutral colour balance.
   • It shows no significant compression artifacts, burned-out highlights, image noise ("graininess") or other processing anomalies. Examples of common technical problems can be found here.
   • Its main subject is in focus, it has good composition and has no highly distracting or obstructing elements.
   • Exceptions to this rule may be made for historical or otherwise unique images. If it is considered impossible to find a technically superior image of a given subject, lower quality may sometimes be allowed.^[1]
2. Is of high resolution.
   • It is of sufficiently high resolution to allow quality print reproduction. Still images should be a minimum of 1500 pixels in width and height (1500×1500px); larger sizes are generally preferred. The size of animated images is judged less strictly, though larger is still preferred. Further information on image size can be found here.
     • Exceptions to this rule may be made where justified on a case-by-case basis, such as for historical, technically difficult or otherwise unique images, if no higher resolution could realistically be acquired. This should be explained in the nomination so that it can be taken into consideration.
     • Note that vector graphics in SVG format omit any requirement for any pixel count.
     • Animations and video may be somewhat smaller.
3. Is among Wikipedia's best work.
   • It is a photograph, diagram, image or animation which is among the best examples of a given subject that the encyclopedia has to offer.
   • It illustrates the subject in a compelling way, making the viewer want to know more. A photograph has appropriate lighting to maximize visible detail; diagrams and other illustrations are clear and informative.
   • A featured picture is not always required to be aesthetically pleasing; it might be shocking, impressive, or just highly informative. Highly graphic, historical and otherwise unique images may not have to be classically beautiful at all. See these examples for a basic guide.
   • commons:Help:Scanning offers advice on preparing non-photographic media (engravings, illustrations from books, etc) in your possession for Wikipedia.
4. Has a free license. It is available in the public domain or under a free license. Fair use images are not allowed. To check which category a particular image tag falls under, see the list at Wikipedia:File copyright tags.
5. Adds significant encyclopedic value to an article and helps readers to understand an article.
   • The image is used in one or more articles.^[2] It is preferable to wait a reasonable period of time (at least 7 days) after the image is added to the article before nominating it, though this may be ignored in obvious cases, such as replacing a low-resolution version of an image with a higher resolution of the same image.
   • A picture's encyclopedic value (referred to as "EV") is given priority over its artistic value.^[3]
6. Is verifiable. It is supported by facts in the article or references cited on the image page, or is from a source noted for its accuracy. It is not created to propose new original research, such as unpublished ideas or arguments.
7. Has a descriptive, informative and complete file description in English. A complete file description:
   • Properly identifies the main subject, including Latin and technical names where applicable.
   • Describes the context of the photograph, painting, or other medium. Geotagging photographs of identifiable places is encouraged. This entails providing the coordinates of where the camera was when the medium was recorded to an appropriate degree of precision no less than ~10 km² (see Commons:Geocoding, or Template:Coord if the image is hosted on the English Wikipedia).
   • States the most relevant meta-detail (such as date, location, event, version, etc). It is suggested that additional relevant information that becomes known during the course of the nomination be subsequently included in the file description.
   • May include languages other than English but there must be an English version available that meets this criterion. The file name may be in a language other than English.
8. Avoids inappropriate digital manipulation.
   • Digital manipulation for the purpose of correcting flaws in a photographic image is generally acceptable provided it is limited, well-done, and not deceptive.
   • Typical acceptable manipulation includes cropping, perspective correction, sharpening/blurring, and colour/exposure correction.
   • More extensive manipulation should be clearly described in the image text.
   • Any manipulation which causes the main subject to be misrepresented is unacceptable.
   • Note that this criterion is not relevant to vector-based SVG images, as the entire image is a digital construction.

1. Well-written:
   1. the prose is clear, concise, and understandable to an appropriately broad audience; spelling and grammar are correct; and
   2. it complies with the Manual of Style guidelines for lead sections, layout, words to watch, fiction, and list incorporation.
2. Verifiable with no original research:
   1. it contains a list of all references (sources of information), presented in accordance with the layout style guideline;
   2. reliable sources are cited inline. All content that could reasonably be challenged, except for plot summaries and that which summarizes cited content elsewhere in the article, must be cited no later than the end of the paragraph (or line if the content is not in prose);
   3. it contains no original research; and
   4. it contains no copyright violations or plagiarism.
3. Broad in its coverage:
   1. it addresses the main aspects of the topic; and
   2. it stays focused on the topic without going into unnecessary detail (see summary style).
4. Neutral: it represents viewpoints fairly and without editorial bias, giving due weight to each.
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 media such as images, video, or audio:
   1. media are tagged with their copyright statuses, and valid non-free use rationales are provided for non-free content; and
   2. media are relevant to the topic, and have suitable captions.

1. The article is suitably referenced, with inline citations. It has reliable sources, and any important or controversial material which is likely to be challenged is cited. Any format of inline citation is acceptable: the use of <ref> tags and citation templates such as {{cite web}} is optional.
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 does not need to be of the standard of featured articles. The Manual of Style does not need to be followed rigorously.
5. The article contains supporting materials where appropriate. Illustrations are encouraged, though not required. Diagrams, an infobox etc. should be included where they are relevant and useful to the content.
6. The article presents its content in an appropriately understandable way. It is written with as broad an audience in mind as possible. The article should not assume unnecessary technical background and technical terms should be explained or avoided where possible.

• 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
