Math Kangaroo Scores, Ranks and Awards, Explained

A Math Kangaroo result has four parts: a score, a national rank and a state rank (if your child placed), and two percentiles. This guide explains each one using Math Kangaroo USA’s own scoring, awards and results pages. Where Math Kangaroo doesn’t publish something, such as an average score or a cutoff for a “good” score, we say so instead of guessing.

For the test itself (question types, timing, topics), see our Math Kangaroo format guide.

How the score adds up

The score is the sum of the points for each correct answer. There are three point values, and the questions are grouped by them:

Nothing is taken away for a wrong answer, so a blank can only cost points. If your child runs short on time, a guess on every remaining question is the right move.

Two things follow from the table:

• Scores from grades 1–4 and grades 5–12 aren’t on the same scale. A 4th grader’s 72 is 75% of the top score; a 5th grader’s 72 is 60%. Moving from 4th to 5th grade adds six questions and 24 possible points.
• The score alone doesn’t tell you which questions were missed. At grades 1–4, a 61 could be every 3- and 4-point question plus one 5-pointer, or five 3-pointers, four 4-pointers and six 5-pointers. Math Kangaroo posts the answer key one month after the contest, also in your registration account, which is where to start if you want to see what went wrong.

What a national or state rank means

Ranks go by score, not by the number of students. Math Kangaroo puts “the students who earn the twenty highest scores” on the National Winner List, ranked 1 to 20 at each grade, and everyone tied on the highest score ranks 1st and gets a gold medal. So rank 20 means your child had the 20th-highest score at their grade nationwide, shared with everyone else on that score.

That is why the lists are long. In 2026, 7,680 students placed in a national Top 20. Spread over 12 grades, that is far more than 20 children per grade.

A state rank works the same way with the three highest scores in your state at each grade: 1st, 2nd or 3rd, again shared by ties. A child can have a state rank and no national rank, which means their score was among the top three in the state but not among the top 20 in the country.

Ranks are by single grade, even though the test is written for two-grade bands (grades 1–2 take one test, 3–4 another, and so on). A 3rd grader is ranked only against other 3rd graders, which our Math Kangaroo prep guide covers in more detail.

What the percentile means

Math Kangaroo defines it as “the percentage of students whose scores are lower than your student’s score at that grade.” Every child gets two: one for the state and one for the nation.

• A national percentile of 90 means 90% of students in your child’s grade nationwide scored lower.
• The two can differ, because the state percentile compares your child only with students in the same grade in your state.
• The percentile is the only fair way to compare a result across years. A 3rd grader and the same child as a 4th grader take the same level of test a year apart, so a higher score is expected; a rising percentile shows real progress against their own grade.

So what is a good Math Kangaroo score?

Math Kangaroo USA does not publish an average score or a score that counts as “good” on its scoring, awards or results pages. Any cutoff you see quoted elsewhere is someone else’s estimate.

What the official numbers do support:

• The percentile is the best measure of “good” because it compares your child with their own grade that year.
• A national Top 20 place is less rare than it sounds. Math Kangaroo reports 60,504 participants and 7,680 national Top 20 places in 2026. By our arithmetic that is about 1 in 8 students.
• For a first contest, a useful goal is the 3-point questions. They are the first third of the test, and getting most of them right is a solid base to build on next year.

Awards, and what every child gets

Every participant receives “a mathematical gift, a participation ribbon, and an electronic certificate of participation.”

Winners receive more, by grade:

Math Kangaroo says gifts “may include: books, games, gift cards, toys, digital kits,” and larger awards may include college grants, cash awards and summer math camps, with priority going to “students who participated in Math Kangaroo for several years with top scores.” Awards must be claimed by September 1 of the contest year. The exact prizes change each year; 2026’s are in the table below.

When results come out

For the 2027 contest date and registration, see our Math Kangaroo 2027 page.

If the score looks wrong

Math Kangaroo keeps answer sheets for eleven months. For a photocopy of the answer sheet or a re-score, it asks for a $15 donation; email info@mathkangaroo.org with the student’s ID, name, grade and test location, and allow up to two weeks.

Before you ask, check the four reasons Math Kangaroo lists for a lower-than-expected score: an answer marked inaccurately, a wrong answer, a missing answer, or more than one answer for the same question. The first and last are worth practicing at home: one clear mark per question.

Dates and deadlines

As of October 2026, from Math Kangaroo USA’s home and 2026 awards pages. Confirm on mathkangaroo.org before relying on it.

Using the result to plan next year

1. Write down the national percentile. It is your baseline for next year.
2. Ask your child which questions felt hardest, and whether they ran out of time. Time trouble and hard problems need different fixes.
3. Practice by point value. Work until the first third of a practice test feels easy, then move up to the 4-point questions. Our free Math Kangaroo practice problems come by grade band (1–2, 3–4, 5–6, 7–8) with worked solutions.
4. Plan when to start. Our prep guide has a month-by-month timeline and an honest look at whether Math Kangaroo is worth it for your child.

Frequently asked questions

What is a good Math Kangaroo score? There is no official cutoff or published average. Use the percentile: it compares your child with every student in the same grade.

What does “national rank 20” mean? Your child had the 20th-highest score at their grade in the country. Everyone with that score shares the rank.

When do Math Kangaroo results come out? By May 1, in the student registration account. The answer key comes out one month after the contest.

Can my child’s test be re-scored? Yes, while the answer sheets are kept (eleven months), for a $15 donation, by emailing info@mathkangaroo.org.
