For the 2022 Ross Mathematics Program, the application window will be open in January 2022. The Ross Admissions Committee will start making acceptance decisions in March.

The 2021 Ross Mathematics Program was online, running from
    Sunday June 27   through   Friday August 6, 2021

During those six weeks, all students attended synchronous lectures on Number Theory. To solve time zone challenges, those lectures were offered every weekday at 11 AM and again at 8 PM, Eastern Time. In addition, participants attended small-group meetings every day to discuss the problem sets. Each group was guided by a Ross counselor.

NOTE: Some of the information below refers to the in-person Ross Program.
More detailed plans for the online program will be sent to accepted participants.


The Ross Program is an intensive summer experience designed to encourage motivated pre-college students to explore mathematics. During those weeks, students are immersed in a world of mathematical discovery.

Dr. Arnold Ross founded this multi-level program at Notre Dame University in 1957. Its growth was then spurred by the launch of the Sputnik satellite and the subsequent surge of interest in science education. Arnold Ross’s Program has run every summer since then, associated mostly with Ohio State University from 1964 through 2018. In 2019 the Program moved to Ohio Dominican University, and in 2020 the program was entirely online.

Our central goal has always been to instruct bright young students in the art of mathematical thinking and to inspire them to discover for themselves that abstract ideas are valuable and important. First year participants take the basic course in number theory. For most students, this is the first time they are asked to consider entirely new questions, to develop methods that they have not seen before, and to justify every answer.

The value of a mathematics education lies not only in obtaining proficiency in computational tasks, but also in building a foundation for critical thinking. Students who have never asked why things work the way they do are not prepared to lead the way to future scientific innovation. It is precisely this independence of thought and questioning attitude that the Ross Program strives to nurture.

Ross Program in Asia.
The Ross/Asia program has been cancelled for 2021.
In 2022 we hope to be able to offer a Ross session at a location in China or in a country nearby.


Ambitious pre-college students with interests in mathematics and science are invited to apply. First-year students range in age from 15 to 18 years old. (In rare cases, younger or older students are accepted.) Admission decisions are based on several criteria, including: school transcripts; teacher recommendations;
essays concerning the applicant’s interests and goals; and the applicant’s work on some challenging math problems.

Undergraduate math majors and math graduate students are invited to apply to be a Ross Counselor.

NOTE. The Ross Program cannot accommodate students who must arrive more than two days after the start of classes.

Costs and Financial Aid

Each Ross student is asked to pay a program fee of $1500. Those funds are used to hire instructors and counselors, and also cover costs for developing new courses.

NOTE: Financial aid is available. Accepted applicants are encouraged to apply if their families have some financial need. We hope to provide enough support to enable every accepted applicant to attend this great Program.

To Apply

Each January, the Ross Program application is posted on the to apply page. In March, The Ross Admissions Committee starts the admissions process.
The final application deadline is April 1.
The Admissions Committee will start making acceptance offers in mid-April, and the process should be completed by May.

The Ross Program admits students of any race, color, gender, and national or ethnic origin.

Ross Program Support

The Ross Program is supported in several ways. Partners in this mathematical enterprise include:

American Mathematical Society

Jane Street

Some other excellent summer mathematics programs are listed on the AMS mathcamps webpage. The two programs closely related to Ross are PROMYS at Boston University, and the Honors Summer Math Camp at Texas State University.
