Paralympic Sport Clubs are community-based programs developed to involve youth and adults with physical and visual disabilities in sports and physical activity, regardless of skill level.  And is designed as a program to be implemented within an agency or organization's program.

Does this mean I have to be ready to try out for the Olympics?

No (unless you want to). 
 
The primary objectives of Paralympic Sport Clubs include:

• To develop community-based sports clubs that recruit and involve youth and adults with physical and visual disabilities in sports and physical activity regardless of skill or interest level.
• To develop a comprehensive, community-based Paralympic Sport Club network as a foundation for a Paralympic athlete pipeline.
• To provide community-based sport program opportunities for injured service members to continue sport participation upon their release from Military Treatment Facilities (MTF).
• To create a national, unified, community-based Paralympic Sport Club network that provides a "grass-roots" branding campaign to educate America on the opportunity and benefits inherent in sport and physical activity as practiced by persons with physical and visual disabilities.
