When is the registration deadline?

Registration deadlines vary by country and by contest cycle, because each participating country runs its contest sitting on its own schedule.

• Your school's contest coordinator or your country page lists the current deadline for your region.
• Global Round registration has its own separate deadline, communicated in the invitation email sent to qualifying families.

If a deadline has just passed and you missed it, contact us right away — we will tell you honestly whether anything can be done for the current cycle.
