PDL is a development league sponsored by United Soccer Leagues in the United States and Canada, forming part of the United States soccer league system. It is currently considered the top-level men's amateur soccer competition in the United States. The league has 65 teams competing in four conferences, split into ten regional divisions. Unofficially, it is considered to be the fourth tier of competition, behind Major League Soccer, the North American Soccer League and the United Soccer League (USL Pro). With USL Pro re-branding as the United Soccer League in February 2015, the PDL dropped the "USL" descriptor from their name, simply operating as the "Premier Development League".
K-W United FC are the current PDL champions, having defeated the New York Red Bulls U-23 4–3 in the 2015 PDL Championship game on August 2, 2015
