ANS has practice groups for basketball in U8 (born 2016/17), U10 (2014/15), U12 (2012/13), U12/14 Girls (2009-2013), U14 Boys (2010/11) and U18boys.

From U10 upwards we regularly compete in games and events versus other schools, clubs and academies, and our U18 Boys team competes internationally at AASCA (The Association of American School in Central America) events as well as in various local competitions, several hosted by ANS (for more information regarding U18 age groups please see Varsity teams).

ANS has a strategic partnership with the National Federation which sees select students participate in special events throughout the year, here on campus.
