This template combines talk page banners into a nested shell and displays a general quality assessment for an article. It was designed for WikiProject banners and will work reliably only with such templates. This template may be added to an article talk page with no WikiProject banners, but with a |class= quality assessment value, in which case it will populate a general category such as Category:C-Class articles.

WikiProject assessment bots may change shell templates per this usage guideline when the bot is editing the talk page for other reasons. If local consensus on a talk page is to not follow this guideline, please specify |collapsed=yes or |collapsed=no explicitly to override the bots.

In February 2023, the Wikipedia community expressed strong support for article quality assessments that are independent of WikiProjects.

Consensus was found for adding a |class= parameter to Template:WikiProject banner shell, which all projects would inherit. To avoid redundancy, this rating is then shown only on the banner shell. Projects can choose to opt-out of this system by adding the parameter |QUALITY_CRITERIA=custom to their project banner template.

It is also possible to add a standalone banner shell template to an article without any WikiProjects, for example {{WikiProject banner shell|class=start}}.

Cewbot will regularly maintain {{WikiProject banner shell}}.

All parameters are optional.

Pages where expansion depth is exceeded issue: This "shell template" adds to the "expansion depth" of the page. In certain circumstances, it can cause the page to exceed the limit. If this happens, find out which enclosed template is already "near the limit" and notify the WikiProject responsible for that template that there is an issue. Include details, as some WikiProject templates only get "close to the limit" with uncommon combinations of parameters. (Example report)
