Copied from en.wikipedia.org/wiki/United_States_of_America_Computing_Olympiad:
The United States of America Computing Olympiad (USACO) is a computer programming competition primarily for secondary school students in the United States. The USACO offers four competitions during the academic year in four increasingly difficult divisions: Bronze, Silver, Gold and Platinum. Participants advance through the levels by performing well in their current division. A week-long summer training camp is held where four students are selected from a group of 24 finalists to represent the United States at the International Olympiad in Informatics (IOI). All expenses are paid for the training camp and competition at IOI. The USACO was founded in 1992 by Don Piele at the University of Wisconsin–Parkside and is currently maintained by director Brian Dean at Clemson University and a dedicated volunteer coaching staff.
