A New Home for Caribou Contest Students
The Caribou contest has ended. Our next round is Oct 6–7, and it's free for everyone.
If your child wrote the Caribou contest, this will feel familiar — six online rounds a season, graded by grade, with solutions after each one. Round 1 is free to enter.

What's the Same, and What's Different
The same cadence of online rounds through the school year, and the same emphasis on thinking over speed. What's different: every question is written fresh by North Star.
Grade-specific rounds
Questions built for your child's grade, not a one-size paper.
Six rounds a season
October to spring, each about 30–45 minutes, written online from home.
Certificates and rankings
Plus video solutions for every question after the round closes.
Round 1 runs Oct 6–7, 2026 and is free for everyone. If your child wants to continue, the remaining five rounds are covered by a paid pass.
