Math Kangaroo (officially the Math Kangaroo International Competition in Mathematics) is an annual multiple-choice mathematics competition held each March for students in grades K–12 across all 50 US states and territories. It is part of the global Kangourou sans Frontières network, which runs the competition in 90+ countries; students outside the US participate through their national chapter.
Participants write at their school grade level; kindergarten students may take the Grade 1 test. Problems emphasize logical reasoning and creative problem-solving rather than rote computation. Students may participate in-person at a registered Math Kangaroo center or online. Results include national and state rankings, with award ceremonies held each May.
Registration opened September 15, 2026 for the March 18, 2027 individual competition. School center registration closes December 15, 2026, regular student enrollment December 31, 2026 and late enrollment February 1, 2027.
Sources checked November 4, 2026: the official 2027 registration page and its 2027 school invitation confirm the dates above, a 75-minute test, USD20 regular entry, USD35 late entry, no school application fee and a 50% Title I school discount. The homepage explicitly dates enrollment opening September 15, 2026. Undated test FAQs and the faculty calendar still quote USD18 regular entry; the cycle-specific 2027 sources support USD20.
The registration page currently advertises available in-person and proctored online centers, while its remote and self-proctored virtual sections say closed without a separate dated cycle label. Do not assume every online mode is available. Proctored options offer official scores/rankings; self-proctored virtual participation has different recognition. The generic eight-level claim has been removed because current rules instead require participation at the student's grade level. Later individual-cycle dates are not verified.
