The following table summarizes the scheme for grading the quality of Systems articles. It follows the Wikipedia 1.0 {{Grading scheme}}, except for an additional Bplus-Class class for articles which are essentially Good Article quality, particularly in terms of content, but have not been passed by the good article peer review process.

The quality gradings that can be assigned to an article, in rough order from highest to lowest, are FA (Featured Article), A, GA (Good Article), B+, B, Start, and Stub. Detailed information is provided in the table.


Quality Criteria Reader's experience Examples
Editor's experience
Featured article FA
{{FA-Class}}
Reserved exclusively for articles that have received featured article status after peer review, and meet the current criteria for featured articles. Definitive. Outstanding, thorough article; a great source for encyclopedic information. Trigonometric function (Mar 2, 2007)

Leonhard Euler (Mar 2, 2007)

No further editing is necessary unless new published information has come to light; but further improvements to the text are often possible.
A-Class article A
{{A-Class}}
Provides a well-written, reasonably clear and complete description of the topic, as described in "How to write a great article". It should be of a length suitable for the subject, with a well-written introduction and an appropriate series of headings to break up the content. It should have sufficient external literature references, from text-books or peer-reviewed papers, rather than websites. Should be well illustrated, with no copyright problems. At the stage where it could at least be considered for featured article status; corresponds to the "Wikipedia 1.0" standard. Very useful to readers. A fairly complete treatment of the subject. A non-mathematician would typically find nothing wanting. May miss a few relevant points. Fermat's last theorem (Mar 2, 2007)

Regular polytope (Mar 2, 2007)
Manifold (Mar 2, 2007)

Minor edits and adjustments would improve the article, particularly if brought to bear by a subject-matter expert. In particular, issues of breadth, completeness, and balance may need work. Peer-review would be helpful at this stage.
GA
{{GA-Class}}
This class is for articles of B+ quality which have also passed through the good article nomination process and meet the good article standards. Note that the good article designation is not a requirement for A-Class. A-Class articles which meet good article standards should be considered for featured article status. As good as a B+ article, but may also have more polished presentation, more illustrations, more detailed history, and more references. Euclidean geometry (Mar 2, 2007)

Ordinal number (Mar 2, 2007)
Homotopy groups of spheres (Mar 2, 2007)

Further editing will clearly be helpful, but not necessary for a good reader experience.
A-BB+
{{Bplus-Class}}
The article has most of the elements described in "start" and may be regarded as a complete article. It is broad in its coverage, while staying focussed on the topic; it is factually accurate, verifiable and neutral; and it is well presented, both in terms of grammar, and adherence to some of the main points in the manual of style. The article is well-referenced, and is illustrated, where appropriate, by an image or images which comply with copyright guidelines. It has the potential to become a good article. Among Systems articles these are some of the best; however, Wikipedia 1.0 does not currently have a B+-Class. Useful to nearly all readers. A good treatment of the subject which attempts to be as accessible as possible, with a minimum of jargon. No obvious problems, gaps, excessive information. René Descartes (Mar 2, 2007) Introduction to general relativity (Mar 2, 2007)
May be improved by input from experts to assess where coverage is still missing, and also by illustrations, historical background and further references. Consider peer review or nominating for good article status. If the article is not already fully wikified, now is the time.
B
{{B-Class}}
The article has several of the elements described in "start", and usually a majority of the material needed for a complete article. Nonetheless, it has significant gaps or missing elements or references, needs substantial editing for English language usage and/or clarity, balance of content, or contains other policy problems such as copyright, neutral point of view (NPOV) or no original research (NOR). With NPOV a well written B-class may correspond to the "Wikipedia 0.5" or "usable" standard. Articles that are close to GA status but don't meet the good article criteria should be B- or B+-Class articles. Useful to many, but not all, readers. An interested reader flipping through the article may feel that they generally understood the topic. However, it may not be as accessible as it could be, or it may be inadequate for a serious student or researcher trying to use the material, who might have trouble or risk error using the article in derivative work. Set (Mar 2, 2007)
Limit (Systems) (Mar 2, 2007)
Vector space (Mar 2, 2007)
Considerable editing is still needed, including filling in some important gaps or correcting significant policy errors. Articles for which cleanup is needed will typically have this designation to start with.
Start
{{Start-Class}}
The article has a meaningful amount of good content, but it is still weak in many areas, and may lack a key element such as a standard infobox. For example an article on groups might cover the theory well, but be weak on history and motivation. Has at least one serious element of gathered materials, including any one of the following:
  • a particularly 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
Useful to some, provides a moderate amount of information, but many readers will need to find additional sources of information. The article clearly needs to be expanded. Hypergraph (Mar 2, 2007)
Esther Szekeres (Mar 2, 2007)
Theorem (Mar 2, 2007)
Substantial/major editing is needed, most material for a complete article needs to be added. This article still needs to be completed, so an article cleanup tag is inappropriate at this stage.
Stub
{{Stub-Class}}
The article is either a very short article or a rough collection of information that will need much work. It is usually very short, but can be of any length if the material is irrelevant or incomprehensible. Possibly useful to a mathematician who has no idea what the term meant. May be useless to a non-mathematician, or a reader only passingly familiar with the term. Ideally it is at least a brief, informed definition. Selig Brodetsky (Mar 2, 2007)
Parallel curve (Mar 2, 2007)
Algebraic number theory (Mar 2, 2007)
Any editing or additional material can be helpful.
