Wikipedia:WikiProject Engineering/Assessment

Welcome to the assessment page for WikiProject Engineering.

What is the purpose of article assessments?

The assessment system allows a WikiProject to monitor the quality of articles in its subject areas, and to prioritize work on these articles. The ratings are also used by the Wikipedia 1.0 program to prepare for static releases of Wikipedia content.

Are these ratings official?

Not really; these ratings are meant primarily for the internal use of the project, and usually do not imply any official standing within Wikipedia as a whole.

Who can assess articles?

In general, anyone can add or change an article's rating. However, the "GA" and "FA" labels should only be used on articles that have been reviewed and are currently designated as good articles or featured articles, respectively. Individual WikiProjects may also have more formal procedures for rating an article, and please note that the WikiProject bears ultimate responsibility for resolving disputes.

How do I assess an article?

Consult the quality scale below; once you have chosen the level that seems to be closest to the article, set the class parameter in the WikiProject banner template to the level's name (omitting "Class" from the end). For example, to rate an article as "B-Class", use |class=B in the banner. Again, the "FA" and "GA" labels should not be added to articles unless are currently designated as such.

Someone put a project banner template on an article, but it's not really within the WikiProject'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 article's talk page (or directly with the person who tagged the article).

What if I don't agree with a rating?

Feel free to change it—within reason—if you think a different rating is justified; in the case of major disputes, the WikiProject as a whole can discuss the issue and come to a consensus as to the best rating.

Aren't the ratings subjective?

Yes, they are somewhat subjective, but it's the best system we've been able to devise. If you have a better idea, please don't hesitate to let us know!

Why didn't the reviewer leave any comments?

Unfortunately, due to the volume of articles that need to be assessed, we are unable to leave detailed comments in most cases. If you have particular questions, you might ask the person who assessed the article; they will usually be happy to provide you with their reasoning.

What if the article is within this project's scope but doesn't have a project banner on its talk page?

Due to the large number of articles we cover, not all articles within our scope can be tagged. However you can help increase the number of tagged articles by tagging the talk page of any untagged articles within our scope you come across with {{Engineering}}.

Any member of Wikiproject Engineering are invited to rate articles for the project. Articles with unassessed quality can be found at Category:Unassessed Engineering articles and articles with unassessed importance ratings can be found at Category:Unknown-importance Engineering articles

For example adding {{WikiProject Engineering|class=B|importance=mid}} produces:

Engineering B‑class Mid‑importance

This article is within the scope of WikiProject Engineering, a collaborative effort to improve the coverage of engineering on Wikipedia. If you would like to participate, please visit the project page, where you can join the discussion and see a list of open tasks. B This article has been rated as B-class on Wikipedia's content assessment scale. Mid This article has been rated as Mid-importance on the project's importance scale.

An article's quality assessment is generated from the class parameter in the {{WikiProject banner shell}}. Articles that have the {{WikiProject Engineering}} project banner on their talk page will be added to the appropriate categories by quality.

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

FA (for featured articles only; adds articles to Category:FA-Class Engineering articles)		FA
A (adds articles to Category:A-Class Engineering articles)		A
GA (for good articles only; adds articles to Category:GA-Class Engineering articles)		GA
B (adds articles to Category:B-Class Engineering articles)		B
C (adds articles to Category:C-Class Engineering articles)		C
Start (adds articles to Category:Start-Class Engineering articles)		Start
Stub (adds articles to Category:Stub-Class Engineering articles)		Stub
FL (for featured lists only; adds articles to Category:FL-Class Engineering articles)		FL
List (adds articles to Category:List-Class Engineering articles)		List

For non-standard grades and non-mainspace content, the following values may be used for the class parameter:

This table is transcluded here, and is identical to the one at Wikipedia:Version 1.0 Editorial Team/Assessment.

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

The following values may be used for the importance parameter to describe the relative importance of the article within the project (see Wikipedia:Version 1.0 Editorial Team/Priority of topic for assessment criteria):

• American Institute for Medical and Biological Engineering - New article, requesting assessment. :FingersOnRoids|FingersOnRoids♫]] 00:52, 25 March 2009 (UTC)

• I've rated it as start-class (due to short length, lack of wikilinks, and few sources) and mid-importance. Anyone should feel free to be bold in changing the assessment if they disagree, since both ratings are just my opinion. --Explodicle (T/C) 00:38, 26 March 2009 (UTC)[reply]

• Six Sigma. An anonymous editor added {{WikiProject Engineering}} in this edit which may have been mistaken for vandalism. My request is for a project member to determine if Six Sigma should receive a WikiProject Engineering rating and, if so, restore the template and rate the article. I've also cross-listed this request under {{WikiProject Technology}}.
