Is there a registration fee for participating in the Open Round (February 4) or Invitational Round (March 10)?
The participation is free of charge, which means that students and teachers do not need to pay for the registration. Note however that, if teachers organize a local competition site at their high school, rather than participating at one of the university sites, then they will incur expenses for printing the booklets and then either scanning the solutions or hard-mailing them to the conference organizers. The NACLO committee normally does not cover these local expenses.
