Vital articles is a list of subjects for which Wikipedia should have corresponding high-quality articles. It serves as a centralized watchlist to track the status of Wikipedia's most essential articles. This is one of the sub-lists of the fifty thousand article Vital articles/Level 5 and is currently under construction.

Articles in the Vital list have their assessments labelled as:

  • Featured articles
  • Former featured articles
  • A-class articles
  • Good articles
  • Delisted good articles
  • Failed good article nominees
  • B-class articles
  • C-class articles
  • Start-class articles
  • Stub-class articles
  • List-class articles
  • Unassessed articles

The progress bar is auto-updated via category count, and the symbols and article counts are updated daily by User:cewbot. Please read the FAQ before modifying the article list.
