{{Category class|topic=|class=|sort=|parent=}}

This template can be used to add a navigation bar to "assessment by topic" category pages that follow the naming convention "Category: class-Class topic articles" (e.g. Category:Start-Class history articles) in order to facilitate navigation between the various assessment class categories for that topic. By default, the template will also add the category to the parent categories "Topic articles by quality" (e.g. History articles by quality) and "class-Class articles" (e.g. Start-Class articles).

• |topic=Unassessed - If the "Unassessed" category exists, the link will go to "Unassessed topic articles".
• |class=Image/Category/Disambig/Portal/Redirect/Template/Project/NA/etc. - If the corresponding category exists, the link will go to "class-Class topic articles".
• |parent=WikiProject "parent" articles by quality - If the parent category does not match the child categories defined in topic, then use this parameter. See Category:FA-Class school articles for an example of this usage.

• |custom1=, |custom2= (optional) - allows for addition of custom classes such as the Audio-Class, for example |custom1=Audio
