The Boise Nationals Soccer Club is a member of the Idaho Youth Soccer Association (IYSA) and US Club Soccer.  During the fall and spring seasons, all BNSC teams participate in the IYSA District 3 League (D3).  D3 encompasses the Treasure Valley and surrounding areas.  Teams are grouped into 4-8 team divisions within D3 and may earn promotion (win your division and move up to the higher division) or relegation (last in your division and move down).  Most D3 games are played at Simplot Sports Complex, one of the premier soccer facilities in the Far West Region, and just east of Boise.
