High school juniors (including home schooled) residing in the United States are eligible, if they live no closer than 50 miles from Boston. Students residing within driving distance from Boston should apply to the MIT section of PRIMES. Sophomores may be allowed to apply, if they plan to graduate one year early, and can provide a confirmation letter from school.

It is not required but preferable that the applicant meets one of these criteria:

- USAMO or USAJMO qualifier;
- grade A for a college-level proof-based math course (online courses included);
- participation in Canada/USA MathCamp, HCSSiM, PROMYS, Ross Program, or SUMaC with a letter of recommendation from a counselor;
- a letter of recommendation from a college professor of mathematics.


Application includes several components: an online questionnaire, solutions to a math problem set, and 2-3 letters of recommendation from people who know you well, preferably from those familiar with advanced mathematics, such as math teachers, counselors in math camps, or college professors.


The deadline for receiving applications and letters of recommendation for the 2018 cycle was December 1, 2017. The admissions are now closed.

Admission decisions are based on all components of your application. Admission decisions are made by early January.

For the 2019 cycle, a new problem set will be posted and admissions open in mid-September 2018.

There is no application fee.


We suggest a list of recommended readings as a preparation for entering PRIMES-USA and as a background for further research. You may find it useful to consult previous years' problem sets and solutions:
