Overview of the USA Triathlon American Development Model 

The American Development Model (ADM) is a concerted effort between the United States Olympic Committee (USOC) and its National Governing Bodies of sport to apply long-term athlete development principles in a way that resonates with the culture of sport in the United States. By creating early positive experiences across all sports, the model aims to promote sustained sport participation, improve the well-being of future generations in the United States and grow the athlete pipeline.

The USOC ADM suggests that quality sport experiences should incorporate five key principles, which in turn, will help keep more Americans engaged in sport. 

  1. Universal access to create opportunity for all athletes
  2. Developmentally appropriate activities that emphasize on motor and foundation skill development
  3. Encourage multi-sport participation
  4. Fun, engaging and challenging atmosphere
  5. Quality coaching at all age levels

USA Triathlon supports the ADM philosophy and believes that creating early positive experiences for all athletes, and following the stage progressions, the ADM will help keep more children engaged in sport longer.

Athletes should consolidate sport specific technical skills with an increased emphasis on triathlon specific skills (in the later time period of this stage). Social and emotional considerations are addressed by placing an emphasis on team-building, group interaction and social activities.

*At this stage, athletes 13+ may consider the draft-legal pathway (see alternative pathway stages).
