The template assigns an article to specific subcategories of Category:Articles needing expert attention, depending on the topic of the article. These subcategories are named after WikiProjects. Find at least one appropriate subcategory when adding this template! Category:Articles needing unspecified expert attention should always remain empty.

Anyone placing this statement must state why an expert is needed, by using either the |reason= or |talk= (to link to a talk page section) parameter. If you place this template without this, any editor may immediately remove it without explanation. Uses of this template with neither a |reason= or |talk= parameter are categorized in Category:Articles needing expert attention with no reason or talk parameter

Use this tag when you have identified a specific issue that requires help from a subject-matter expert (not a generally knowledgeable Wikipedia editor).

If you want help for most of the page, or if you want help soon, then try these much more effective options:

• Leave a note on the talk page of any relevant WikiProjects.
• Submit the article for Wikipedia:Peer review.
• Take questions to relevant content-related Wikipedia:Noticeboards, such as the Wikipedia:Reliable sources/Noticeboard for questions about whether sources are reliable for the statements they support.
• Start a Wikipedia:Request for comment.
• Ask for help at the Wikipedia:Village pump (miscellaneous).

{{Expert needed|WikiProject|talk=|reason=|date=}}

• The first unnamed parameter accepts the name of the WikiProject from Active WikiProjects
• A second optional unnamed parameter, may be used to override the default "article" text with, for example, "section", "diagram" or "paragraph".
• ex2–ex5: To add additional expert subjects, you can use these parameters to include more names of WikiProjects.
• talk: If you have started a discussion on the article's talk page, you may link to that discussion with |talk=, using the section title of the discussion.
• reason: You may use the |reason= parameter to provide a short explanation describing the issue directly within the template, instead of, or in addition to the talk parameter.

Add |talk=, |reason=, or both. Uses of this template with neither may be removed without further consideration.

• date: The date of adding the template may be used as the next parameter, in the form of Month Year.

{{Expert needed|technology|documentation|talk=Section title goes here|reason=reason goes here|date=Month Year}}

This documentation needs attention from an expert in technology. The specific problem is: reason goes here. See the talk page for details. WikiProject Technology may be able to help recruit an expert. (December 2024)

{{Expert needed|technology|ex2=science|ex3=math|talk=Section title goes here|reason=reason goes here|date=Month Year}}

This article needs attention from an expert in technology, science or math. The specific problem is: reason goes here. See the talk page for details. WikiProject Technology, WikiProject Science or WikiProject Math may be able to help recruit an expert. (December 2024)

When using this template, it is essential to provide an explanation using either the "reason" or the "talk" parameter. When adding a section on the talk page, you may use {{expert needed talk}} for this purpose. If the issue is of some urgency, you may also post a notice at the WikiProject that was included in the template.

• This template is a self-reference, and should not be substituted.
• See: WikiProject Council/Directory for a complete list of WikiProjects.
• Where the category name does not match the WikiProject name, including plural words or capitalisation, use the #switch parameter at Template:Expert needed/catcheck. E.g. for WP:WikiProject Radio Stations, the corresponding category is Category:Radio station articles needing expert attention.
