Sources edit
B-class
- It is suitably referenced, and all major points have appropriate inline citations.
GA Review
- It is factually accurate and verifiable:
- (a) it provides references to all sources of information, and at minimum contains a section dedicated to the attribution of those sources in accordance with the guide to layout;[1]
- (b) at minimum, 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;[1] and
- (c) it contains no original research.
Content edit
B-class
- It reasonably covers the topic, and does not contain obvious omissions or inaccuracies.
GA Review
- It is broad in its coverage:
- (a) it addresses the main aspects of the topic;[2] and
- (b) it stays focused on the topic without going into unnecessary detail (see summary style).
- It is neutral: it represents viewpoints fairly and without bias.
- It is stable: it is not the subject of an ongoing edit war or content dispute. Vandalism reversions, proposals to split or merge content, good faith improvements to the page (such as copy editing), and changes based on reviewers' suggestions do not apply. Nominations for articles that are unstable because of constructive editing should be placed on hold.
Structure edit
B-class
- It has a defined structure, including a lead section and one or more sections of content.
Language edit
B-class
- It is free from major grammatical errors.
GA Review
- It is 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.[3]
Supporting material edit
B-class
- It contains appropriate supporting materials, such as an infobox, images, or diagrams.
See also the B-Class assessment & criteria FAQ.
GA Review
- It is illustrated, if possible, by images:[4]
- (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.[5]
- ^ a b In-line citations, if provided, should follow either the Harvard references or the cite.php footnotes method, but not both in the same article. Science-based articles should follow the scientific citation guidelines.
- ^ This requirement is significantly weaker than the "comprehensiveness" required by WP:FAC; it allows shorter articles, articles that do not necessarily outline every part of the topic, and broad overviews of large topics.
- ^ It is strongly recommended that the Manual of Style is broadly followed, but this is not required for good articles.
- ^ Other media, such as video and sound clips, are also covered by this criterion.
- ^ The presence of images is not, in itself, a requirement for Good articles. However, if images (including other media) with acceptable copyright status are appropriate and readily available, then some such images should be provided.
