A-Class

A-Class is a rating given to articles on Wikipedia that meet specific standards of quality, accuracy, and completeness, as determined by the Wikipedia:WikiProject assessment system, which involves WikiProject Council, Wikipedia:Featured article candidates, and Wikipedia:Good article nominations. The A-Class rating is considered to be a high level of quality, indicating that the article is well-written, well-researched, and provides a comprehensive overview of the subject, as seen in articles about Albert Einstein, Marie Curie, and Charles Darwin. A-Class articles are often considered to be among the best on Wikipedia, and are frequently used as examples of high-quality content, such as Wikipedia:Featured articles, Wikipedia:Good articles, and Wikipedia:Vital articles, which include articles on Nobel Prize, Royal Society, and Harvard University.

● Definition

The definition of A-Class is based on the Wikipedia:Content assessment system, which evaluates articles based on their quality, importance, and overall value to the encyclopedia, as outlined by Jimmy Wales, Larry Sanger, and Wikipedia:Community, and is used by WikiProject Medicine, WikiProject Physics, and WikiProject Biology. A-Class articles are defined as those that meet the highest standards of quality, accuracy, and completeness, and are considered to be among the best on Wikipedia, as seen in articles about University of Oxford, University of Cambridge, and Massachusetts Institute of Technology. This definition is based on the principles of Wikipedia:Verifiability, Wikipedia:Neutral point of view, and Wikipedia:Original research, which are essential for articles on NASA, European Space Agency, and CERN. The definition of A-Class is also influenced by the Wikipedia:Manual of Style, which provides guidelines for writing and formatting articles, as used by The New York Times, The Guardian, and BBC News.
