USL Premier Development League
Previously, the berths in the USL Premier Development League were determined by each divisional leader after a select number of PDL regular season matches. For 2012, the PDL was allocated 16 berths, up from eight. Additionally, US Soccer required that all berths be determined by May 5. Therefore, the league decided that 4 clubs from each conference would qualify based on the results from 2011. The top 2 US based clubs from each division in the Central, Southern, and Western conference would qualify. For the Eastern Conference the qualifiers were the top team from each of the three divisions and a "wildcard" from the remaining teams – the team with the most points from the regular season.Since the 1st place team, Thunder Bay Chill, in the Heartland Division is a Canadian club, Real Colorado Foxes qualified for the US Open Cup even though they did not participate in the 2011 playoffs. Likewise, since the 2nd place team in the Northwest Division, Victoria Highlanders, and the 3rd place team, Vancouver Whitecaps Residency, are both Canadian clubs, the 4th place team Portland Timbers U23's qualified. The Eastern conference runner-up, Jersey Express, did not qualify for the Cup.
