This table shows all the occupational safety and health articles on Wikipedia, broken down by their quality (in each row) and importance (in each column).  The number in each cell tells how many OSH articles on Wikipedia have a certain quality and importance, and clicking on it will link to a list of those articles.  The table is useful for finding articles that need improvement, for example, top-importance articles that are stubs or start-class, the two lowest quality classes. The range of quality classes begins with "Stub" (very short pages), followed by "Start", "C" and "B" (in increasing order of quality). Community peer review is needed for the article to enter one of the highest quality classes: either "A", "good article" or the highest, "featured article". A good article (GA) is an article that meets a core set of editorial standards but is not featured article quality. Editors can also rate articles per "importance." For a particular article, different WikiProjects may assign different importance levels.
