Wikipedia:GLAM/Teylers/Assessment

Welcome to the Assessment Division of the Teylers WikiProject. This department focuses on assessing the quality of articles under the scope of the Teylers project. The resulting article ratings are used within the project to aid in recognizing excellent contributions and identifying topics in need of further work.

The assessment is done in a distributed fashion through parameters in the {{WikiProject Teylers}} project banner. The banner automatically adds articles to categories based on quality and importance.

FAQ

1. What is the purpose of the article ratings?

The rating system allows the project to monitor the quality of articles in our subject areas, and to prioritize work on these articles. Please note, however, that these ratings are primarily intended for the internal use of the project, and do not necessarily imply any official standing within Wikipedia as a whole.

2. How do I add an article to the WikiProject?

Just add {{WikiProject Teylers}} to the talk page; there's no need to do anything else.

3. Someone put this project's banner on an article, but it doesn't seem to be within the project'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 project's talk page (or directly with the person who tagged the article).

4. Who can assess articles?

Any member of the Teylers WikiProject is free to add or change the rating of an article. Editors who are not participants in this project are also welcome to assess articles, but should defer to consensus within the project in case of procedural disputes.

5. How do I rate an article's quality?

Check the quality scale below and select the level that best matches the state of the article; then, follow the instructions below to add the rating to the project banner on the article's talk page. Please note that some of the available levels have an associated formal review process that must be followed; this is documented in the assessment instructions.

6. How do I rate an article's importance?

Check the importance scale below and select the level that best matches the subject of the article; then, follow the instructions below to add the rating to the project banner on the article's talk page. Please note that for an article to be added to some of the higher importance levels, the project must be notified in advance on the project talk page.

7. What if I don't agree with a rating? Can I request that someone else rate an article?

Of course; to do so, simply remove the current quality or importance rating already present on the article's talk page. If no rating is currently there, be patient; a member of this project will eventually get around to rating it. If you'd like, you can drop a note at the project talk page to bring the specific article to the attention of our volunteers.

9. What if I have a question not listed here?

For any other issues not covered in this FAQ, leave a message on the project's talk page, and someone will respond to your query directly.

Assessment instructions

By quality

An article's quality assessment is generated from the class parameter in the {{WikiProject Teylers}} project banner on its talk page:

{{WikiProject Teylers|class=???}}

The following values may be used for the class parameter to describe the quality of the article (see Wikipedia:Content assessment for assessment criteria):

Quality scale

The following grading scheme is generic, not customized to WP:Teylers articles.

WikiProject article 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 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. It is: well-written: its prose is engaging 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; 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 compliant with Wikipedia's copyright policy and free of plagiarism or too-close paraphrasing. 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 substantial but not overwhelming system of hierarchical section headings; and 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. 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. Length. It stays focused on the main topic without going into unnecessary detail and uses summary style where appropriate.	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.[under discussion]	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: Prose. It features professional standards of writing. Lead. It has an engaging lead that introduces the subject and defines the scope and inclusion criteria. 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. Structure. It is easy to navigate and includes, where helpful, section headings and table sort facilities. 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. 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.	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.	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: Provides a well-written, clear and complete description of the topic, as described in Wikipedia:Article development. 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).	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 A good article is: Well-written: the prose is clear, concise, and understandable to an appropriately broad audience; spelling and grammar are correct; and it complies with the Manual of Style guidelines for lead sections, layout, words to watch, fiction, and list incorporation. Verifiable with no original research: it contains a list of all references (sources of information), presented in accordance with the layout style guideline; 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); it contains no original research; and it contains no copyright violations or plagiarism. Broad in its coverage: it addresses the main aspects of the topic; and it stays focused on the topic without going into unnecessary detail (see summary style). Neutral: it represents viewpoints fairly and without editorial bias, giving due weight to each. Stable: it does not change significantly from day to day because of an ongoing edit war or content dispute. Illustrated, if possible, by media such as images, video, or audio: media are tagged with their copyright statuses, and valid non-free use rationales are provided for non-free content; and media are relevant to the topic, and have suitable captions.	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 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. 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. 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. The article is reasonably well-written. The prose contains no major grammatical errors and flows sensibly, but it does not need to be "brilliant". The Manual of Style does not need to be followed rigorously. 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. 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.	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

By importance

An article's importance assessment is generated from the importance parameter in the {{WikiProject Teylers}} project banner on its talk page:

{{WikiProject Teylers|importance=???}}

The following values may be used for the importance parameter to describe the relative importance of the article within the project:

Top (adds articles to Category:Top-importance Teylers articles)		Top
High (adds articles to Category:High-importance Teylers articles)		High
Mid (adds articles to Category:Mid-importance Teylers articles)		Mid
Low (adds articles to Category:Low-importance Teylers articles)		Low
Related (adds articles to Category:Related-importance Teylers articles)		Related
NA (adds articles to Category:NA-importance Teylers articles)		NA
??? (articles for which a valid importance rating has not yet been provided are listed in Category:Unknown-importance Teylers articles		???

The importance parameter should be assigned according to the importance scale below.

Importance scale

Label	Criteria	Examples
Top	Articles about specific items in the collection, one of the Teyler societies, the hofje, or one of the curators	Pieter Teyler van der Hulst Atoposaurus Mosasaurus Martin van Marum The Birds of America
High	Scientific discoveries in the collection A few exceptions to be discussed at wt:Teylers	Leiden Jar
Mid	Listed individually on a Teylers list, plus other national or local significance. Click [show] for more information. Most Teylers-listed sites are of low importance. However, as a rule of thumb, 10%-15% of sites in a state or region should be rated at higher importance. These sites could include: structures or locations associated with the collection historic events which involve Teylers Please propose these exceptions at the project talk page.	Mennonites of Haarlem
Low	All other Teylers subjects List-articles subordinate to other Teylers articles	List of Nobel Prize winners
Related	Contributing articles	Koninklijke Hollandsche Maatschappij der Wetenschappen
