Wikipedia:WikiProject Underwater diving/Assessment

Stub and Start
Most WikiProject SCUBA articles are stub- or start-class, and most articles requiring assessment are likely to fall into these classes. To distinguish between them, consider the following points:
 * A stub-class article can be any article that does not establish notability. Look for reliable sources that show that the subject is notable. A completely unreferenced article is unlikely to be able to demonstrate notability.
 * Even if notability is established, a very short article, lacking much more than a bare definition of the subject is unlikely to be more than stub-class.
 * A start-class article will demonstrate notability and contain more than a description of the topic.

Start and C
Distinguishing between these is a grey area, and is likely to be subjective. Some projects don't include C-class for this reason. Consider these points:
 * A start-class article will contain some useful information beyond a stub and will demonstrate notability. However it is likely to be lacking in references to support most of its content.
 * A C-class article will contain a lot of the content covering the topic, although some of it will be unsourced and will probably meet at least one of the B-class criteria (see below).
 * A good C-class article is likely to cover several of the B-class criteria (see below).

C and B
Many projects have well-defined criteria for grading as B-class. All of these have to be met for B-class. These are summarised below:
 * 1) B-Class-1: It is suitably referenced, and all major points have appropriate inline citations.
 * 2) B-Class-2: It reasonably covers the topic, and does not contain obvious omissions or inaccuracies.
 * 3) B-Class-3: It has a defined structure, including a lead section and one or more sections of content.
 * 4) B-Class-4: It is free from major grammatical errors.
 * 5) B-Class-5: It contains appropriate supporting materials, such as an infobox, images, or diagrams.
 * 6) B-Class-6: It presents content in an accessible way.
