The World Series of Innovation (WSI) is a free global innovation competition hosted by the Network for Teaching Entrepreneurship (NFTE), open to young people worldwide. Participants develop entrepreneurial solutions to real-world challenges aligned with the UN Sustainable Development Goals. The competition runs two tracks: the Impact League for ages 13–24 (focused on design thinking and entrepreneurial mindset) and the Imagination League for ages 5–12 (focused on creative problem-solving and opportunity recognition).
Participants submit their solutions via the WSI platform at wsi.awardsplatform.com. The 2025–26 cycle concluded with winners announced April 21, 2026; new challenges for the 2026–27 cycle launched September 9, 2026, with submissions due December 13, 2026.
2026–27 schedule checked November 4, 2026: The participation agreement confirms first-round opening September 9, 2026 at 10 a.m. Eastern, and December 13 at 11:59 p.m. Eastern close for entries. The Impact League page confirms the December 13, 2026 deadline. Selected top-ten Impact teams submit one-minute pitch videos during the final round, February 9–March 2, 2027, with the March 2 close at 11:59 p.m. Eastern. Impact winners are planned for April 21, 2027. These are distinct from Imagination judging.
The Imagination League page also confirms December 13, 2026 entries and parent/teacher help, but says both late February and February 9 for its winners. Exact Imagination results timing remains unresolved. Both leagues allow individuals or teams of up to four and are free; Impact covers ages 13–24 and Imagination ages 5–12. A later-cycle schedule is unannounced.
