What does gradability mean?
Gradability is a rare noun denoting the quality of being gradable. In its most natural educational sense, it means the capacity or likelihood of completing the requirements of a course or programme and graduating. Because this sense overlaps closely with graduability, the latter is normally the safer and more familiar expression; gradability is more likely to occur in formal analysis of student progress, programme completion, or eligibility. The word is abstract rather than concrete: it does not name a particular aptitude, but the state or quality of being able to finish a prescribed path. Its rarity should not be confused with obsolescence; it is understandable and well formed, simply much less frequent than graduability. In contexts where gradable describes a scale or instrument capable of being marked in gradations, gradability can correspondingly refer to that capacity. Overall, it is chiefly an analytical or specialist term rather than everyday vocabulary.
