High school students from around the world are invited to participate in the 2000 U S Open. This is a timed and proctored competition that will be held on Wednesday  April 12, 2000 for  USA students and Thursday, April 13, for International students.

If you are a US participant in the U S Open, you will be eligible to be selected as one of fifteen finalists. All finalists will receive an all expense paid trip to the University of Wisconsin-Parkside to take part in the summer training program, June 20-28. From this program, four students will be selected to represent the United States in two Olympiads in Europe (see BOI and CEOI) and the International Olympiad in China (see IOI). All expenses are paid by our sponsor USENIX.

Local Coordinator
Students in the United States participate through a local coordinator at their school. A local coordinator is an adult who typically supervises or teaches in high school. It is a simple process to become a local coordinator. Simply go to our registration web site at: 


and follow the instructions. No U S student can register directly. Only a local coordinator may register a student. 

A local coordinator will automatically be put on the hs-computing list which it used to distribute information about the USACO. Click on Instructions and read the responsibilities of the local coordinator.

USA Contestants
To participate in the U S Open, a USA student must have his/her name submitted by their local coordinator. 

International Contestants
To participate in the U S Open, an International student need not register. 

The deadline for USA registration is Monday, April 10, 2000. 
Solutions must be submitted within 24 hours after the competition for USA participants. 

New for 2000
This year we are distributing the problems and collecting all solutions via the Internet. For USA contestants, the problems will be emailed to the local coordinator on the morning of April 11, 2000. They will print out the problems for distribution to their registered student the following day, April 12. Instructions for conducting the contest are provided here. 

Once the contest is over on April 12, all solutions will be submitted by email as is done in our Internet competitions. Again, read the Instructions to learn how to do this.

All instructions for International students will be provided when the problems are distributed on April 13.
