Intermediate Our intermediate program is designed for players who want to transition from individual skills to teamwork and competitive games. The age group is usually U9s and U10s boys and girls teams and they are typically 7v7 teams. CASA FC plays in the Colorado Soccer Association (CSA) league, and game seasons run in the Fall and Spring. The Fall season runs from August through November and the Spring season runs from March through May. However, we keep our teams active year-round with leagues and tournaments. In fact, many of our teams in this age group have already started playing against other top teams in the state. We also start traveling to out-of-state tournaments if the team wishes to do so.
