An important tool for evaluating a Wikipedia article is to look at its quality rating.

Wikipedia articles are constantly being improved, and all at a different pace. Some rival the best encyclopedias, but others are out of date or incomplete.

Volunteers review articles and leave a rating on the Talk page. You can find this by clicking "Talk" at the top left of the article.

High quality articles have been evaluated as "Good" or "Featured" articles. These are the best that Wikipedia has to offer, and the rating reflects a consensus among Wikipedians. It can be harder to find ways to improve a Good or Featured article, and any major edits should be mentioned on the article's Talk page before changes are made.

"Start" or "Stub" class articles aren't considered as reliable, or simply don't provide a strong overview of the topic. These are great articles to work on, because there's lots you can do, and you can make a dramatic impact.
