Under-23 sport is a competitive age category grouping within sports for athletes under the age of twenty-three. An extension of age categories found in youth sports, the under-23 category is for adults who are still in a developmental stage within their chosen discipline. The intention of the grouping is to allow such adults to improve their skills against opponents of a similar standard, as opposed to elite level of competition found in open senior level competitions, where they may not receive competitive opportunities or may find their development hindered by significant ability differences.
