Wikipedia:Reviewing good articles

This guideline helps editors review Good article nominations. If you want to discuss the decision of a reviewer, please see Good article reassessment.

Good articles meet a set of minimum standards (the Good article criteria) for quality of writing, factual accuracy and attribution, broadness of coverage, stability, and appropriate use of images. This guideline provides advice on how to review fairly against these criteria and hence decide whether to list a nomination as a Good article.

About the process

The Good article (GA) process is intentionally lightweight. Anyone, including unregistered users, can nominate an article and (subject to the next paragraph) any registered user can review: multiple votes, consensus building, and committees are not required.

A reviewer should be able to read the article critically and apply the Good article criteria fairly. If the reviewer believes that the criteria are met, then the reviewer should list it as a Good article. If any of the criteria are not met, the reviewer has two options:

• If the problems are minor or easy to fix, the reviewer can simply fix them or may place the nomination "on hold" for a period of time to give regular editors of the article time to address the reviewer's suggestions. This is the recommended procedure for typical nominations.
• If the problems are substantial or extensive, the nomination can be failed. In the latter case, the editors at the article should be invited to renominate the article once it has been improved; the Good article criteria are achievable in almost any article, and there is no minimum time between nominations. "Quick-failing" articles sometimes irritates editors who are keen to improve the article. (If you fail an article and then discover that the editors appear willing to make significant improvements, it is possible to re-open the review.)

The nominator is the person who listed the article at the Good article nominations page. It is not a special position, does not indicate that the person has had any involvement in improving the article, and has no duty to participate in the review. All editors at the article are encouraged to participate on an equal basis, but no one is required to participate in the review or interact with the reviewer. In nominating the article, the nominator indicates that he or she believes the article to meet the criteria; if the nominator later changes his mind, he may withdraw the nomination. If the review has not begun, then withdrawal requires only deleting the GA nominations template from the article's talk page. If a review is already underway, then, unless there are exceptional circumstances, the reviewer should promptly close it as "not listed".

The process is dependent on reviewer integrity. Reviewers may not review articles that they have edited significantly, and they should focus on determining whether the article meets the Good article criteria. The review should not be influenced by beliefs about how the article could be made "perfect", by how the reviewer would have written the article, or by personal feelings about the article topic. Reviewers should aim to advise on content and form rather than to impose their preferences. A reviewer involved in a contentious discussion should consider withdrawing, so that a less-involved editor can make the final assessment and decision on the Good article criteria.

Why articles are nominated for Good article status

Nominations are occasionally made by editors who happen upon an article that they believe is good quality, but the majority are made by editors who have spent extensive time working on the nominated article. Such editors have an emotional stake in the article and are usually interested in improving it.

The Good article process is one of Wikipedia's systems for providing a detailed review of an article. Regardless of whether the article meets the criteria, most of the editors at a nominated article appreciate receiving concrete, specific suggestions about how the article could be improved. If making suggestions about how to improve the article, reviewers must clearly differentiate between improvements necessary to meet the actual standard Good article criteria and ideas that might help the article meet A-class criteria or featured article criteria.

How to review a Good article nomination

The process and mechanics of reviewing a nomination are described by the guidelines at the top of Good article nominations page. The guidelines below focus instead on the evaluation and decision-making involved in reviewing a nomination.

First things to look for

Before conducting an extensive review, and after ensuring you are viewing an unvandalized version, check the article and its edit history for the following basic problems which are sometimes found in GA nominations.

1. The article completely lacks reliable sources – see Wikipedia:Verifiability.
2. The topic is treated in an obviously non-neutral way – see Wikipedia:Neutral point of view.
3. There are cleanup banners that are obviously still valid, including {{cleanup}}, {{wikify}}, {{POV}}, {{unreferenced}} or large numbers of {{fact}}, {{citation needed}}, {{clarifyme}}, or similar tags. (See also {{QF-tags}}.)
4. The article is or has been the subject of ongoing or recent, unresolved edit wars.
5. The article specifically concerns a rapidly unfolding current event with a definite endpoint.

If the article has any of the above problems, it may be premature to provide a detailed review, in which case you can fail the nomination in accordance with step two of the GAN guidelines, as long as you explain this clearly on the review page. Reviewers often refer to this as quick-failing and to the five listed issues as the quick-fail criteria. They most commonly apply when the nominator is inexperienced or is not a regular editor of the article. If it is apparent from the article edit history and/or talk page that the nominator has put extensive work into the article, then "quick-failing" is likely to be inappropriate or offensive, as the GA process is intended to help editors with article improvement, not dismiss their work.

Even when an article can be "quick-failed" according to the above criteria, reviewers have three main options:

1. Leave a short note explaining the major problems, but without officially closing the review until the editors at the article have had a few days to respond to your concerns. You may find that they are interested in significantly improving the article.
2. Provide a detailed review, as more specific information will help future editors improve the article to meet all of the Good article criteria, but close the review as "not listed".
3. Withdraw from the review, and let another reviewer decide how to handle it.

Assessing the article and providing a review

If a nomination requires a detailed review, there are two basic steps: assessing the article against the Good article criteria, and communicating this assessment to other editors. For both steps, you may find it helpful to use a checklist, such as {{GAList}}, {{GAList2}} or {{subst:GATable}}; however, this is not required, and if you prefer to communicate your assessment purely in prose, do so.

Step 1. As you read through the article, keep in mind the Good article criteria.

1. The article should be clearly written, in good prose, with correct spelling and grammar. Check for coherent formatting, good organization of the article into sections, appropriate use of wikilinks, and other aspects of the Manual of Style referred to in the Good article criteria. After you have read the article, check that the lead section is a good summary and introduction to the topic.
2. The article should be factually accurate according to reliable sources, with inline citations (typically using either footnotes or Harvard (parenthetical) references) for the six types of material named in the GA criteria. The article should not copy text from sources without quotation or in text attribution, and it should not contain any original synthesis of source material, or other forms of original research. Perfectly formatted citations are not required. Read the detailed guidance at WP:DEADREF before addressing any non-functional URLs.
3. The article should broadly cover the topic without unnecessary digressions. The article may, and sometimes should, go into detail, but it is not required to be comprehensive.
4. The article should be written from the neutral point of view: this viewpoint strives to represent all other views fairly, proportionately, and without bias. Ensure that the article describes disputes without engaging in them.
5. The article should be stable, with no ongoing edit wars: constructive article improvement and routine editing does not apply here.
6. The article should comply with image use policy. Images are encouraged but not required. Any images used should be appropriate to the article, have captions and free licenses or valid fair use rationales.
7. The article is free of obvious copyright violations. Reviewers can use several tools, as well as Google searches, to help establish whether material has been plagiarised or cut-and-paste from some of the electronic sources used; but this is not a trival undertaking.

Ideally, a reviewer will have access to all of the source material, and sufficient expertise to verify that the article reflects the content of the sources; this ideal is not often attained.

• At a bare minimum, check that the sources used are reliable (for example, blogs are not usually reliable sources) and that those you can access support the content of the article (for example, inline citations lead to sources which agree with what the article says) and are not plagiarized (for example, close paraphrasing of source material should only be used where appropriate, with in text attribution if necessary).

• Copyvios and plagiarism might found by detailed checking of referenced material against the declared sources used in the article, but is more difficult in those cases where undeclared sources have also been employed. For book sources: some out of copyright books may be found through ebook sites, electronic archives, and on Google books. For books still in print, Amazon in its many forms (i.e. by country, such as: .com, .ca, .co.uk, .fr, etc) has selected images of some copyrighted books, where the copyright holder has given permission and this may vary from country to country; otherwise the books themselves may need to be consulted in a library and/or borrowed. Some journals and newspapers have also been archived and are available in electonic form, such as The Times, The Washington Post, etc. Some of these may be free, provided that you register with the site; others will be subscription only sites but some public library borrowing cards and/or university library cards do provide free access for their members. Google internet searches can also be used by copying sentences from the article and putting them into the search box. If any are found, the Duplication Detector can be used to detect instances of plagiarism or copyvio. Here the reviewer needs to enter the article's url and the source url into the two fields and the software compares them. It is usually best to start with sentences that appear "out-of-place", though a few sentences should be checked at a minimum.

Step 2. Summarize your assessment on the review page, noting any problems you have found, preferably with specific examples. To avoid conflict and encourage other editors, try to write your review in a positive way, raising problems as opportunities for improvement rather than criticism of previous efforts; suggesting specific fixes can be particularly helpful to other editors.

• If the article meets the criteria, it should be listed as a Good article; bear in mind that future editors may be interested in your reasoning, so don't just leave an all-positive checklist. Suggestions for further improvement may be welcomed by article editors.
• If instead, the article has problems, you need to decide whether to fail the article (leaving a detailed review), or place it on hold. Many of the considerations concerning "quick-failing" apply here. As the nominal hold period is one week (this is a suggestion, not a requirement) one rule of thumb is to consider whether the issues you have raised could reasonably be fixed within such a timescale. If that is possible, then the article should be placed on hold. If you decide not to place the article on hold, ensure your review provides detailed advice for improvement, and encourage editors to renominate the article once the problems have been fixed.

Mistakes to avoid in reviews

Giving problems, not solutions

When reviewing an article, do not just describe its shortcomings, provide suggestions to fix them. For example:

• "The lead is messed up" does not give editors any guidance to make the lead better. Instead, try something like. "The lead does not adequately summarize the article. Try expanding it. See WP:LEAD for more information".

Using the Good article criteria as a guide to organize a review is a good thing, but do not merely use it as a checklist. For example:

• "This article violates criterion 1 of the Good article criteria" with no further information does not help anyone improve the article. Instead, try something like: "This article is dominated by its plot summary and takes an "in-universe" perspective. According to the Manual of Style, an article about a work of fiction should be written primarily from an "out-of-universe" perspective. That needs to be fixed before this can be a Good article."

Imposing your personal criteria

Further information: Wikipedia:What the Good article criteria are not

When reviewing, focus on providing the best review you can for that article. Take care not to be distracted by whether related top-level articles are lackluster, or let frustration over how many articles there are covering a given topic area show through.

Avoid commenting on the perceived "merit" of the subject of the article. If an article on a porn star is well-written, well-organized, well-referenced, and follows the specific content policies and style guidelines that are required by the GA criteria, then you should not fail it because you think Wikipedia has too many articles on porn stars.

Enthusiasm in wanting an article to be the best it can be is admirable, but take care not to impose conditions for passing the article, perhaps based on your own stylistic preferences, that exceed the criteria. In particular, the GA criteria do not require compliance with several major guidelines, including Wikipedia:Notability and the main Wikipedia:Manual of Style page.

Passing articles that do not meet the Good article criteria

Beware of the several temptations to pass an article that does not meet Good article criteria. For example:

• You are a fan of the subject, and want to see the article listed. (Instead, consider improving the article, rather than promoting it.)
• You want to illustrate a point.
• As Good articles are not Featured articles, it is all right to let things slide. (It is not. The standards for Good articles are less exacting than those for Featured articles, but this does not mean that Good articles have no standards.)
• It appears that the article is as good as it will ever get, and will never meet the standards. (Not every article can be a Good article. If the references to improve an article to Good article standards simply do not exist, then you should not overlook that part of the criteria.)
• The editors of the article have obviously spent a considerable effort improving the article during the Good article review process, and even though it does not meet all of the criteria, it is much better than it was when it was first nominated.

Dealing with disputes

While we hope that a Good article review will be a positive, friendly, collaborative experience, disputes sometimes arise. Multiple mechanisms are in place for resolving disputes.

Get a second opinion

If a dispute arises, anyone involved in the review (reviewer, nominator, other editors at the article) can ask for a second opinion.

• Leave a clearly labeled note on the review page that specifies what you'd like from the person giving a second opinion. Do you have a single, specific question? Do you want an overall opinion about whether the article meets the GA criteria? Try to be as direct and specific as possible.
• On the talk page of the article set the GAN status parameter to "2ndopinion" as in {{GA nominee|...|status=2ndopinion}}. The bot will then add a note to WP:GAN that you're looking for a second opinion.
• Alternatively, you can personally request help from an individual, GA mentors, or relevant WikiProject, or use the normal third-opinion process.

Change reviewers

Occasionally, it is necessary to change reviewers in the middle of a review, rather than closing one review and re-nominating the article. Instructions on doing this are given at Wikipedia talk:Good article nominations/FAQ.

Close and re-nominate

If the reviewer is dissatisfied with the article, but the editors of the article are confident that it meets the GA criteria, it is appropriate for the reviewer to close the GA review (as 'not listed'). The editors may re-nominate the article at any time, including immediately. It is generally best for the first reviewer to allow another person to conduct the subsequent reviews. Subsequent reviewers often carefully consider the comments in recent reviews, and the nomination is more likely to be successful if all relevant issues are addressed appropriately before re-nominating the article.

Send it to GAR

WP:GAR—the Good article reassessment process—can be used for both listing or de-listing articles. It is open to articles that have been reviewed at any point in time, but is not normally used for articles whose reviews are currently open.

Delisting older articles

The Good article process has evolved considerably since it began. Despite these changes, and indeed as part of its nature, the Good article process does not always get it right the first time: this is the price paid for the efficiency of the one-nominator:one-reviewer approach. Consequently, if you come across an article which no longer meets the criteria, you may remove it from the Good articles list by following the delisting guidelines. If you believe that an article was improperly listed or delisted, you can raise your concerns at Good article reassessment.
