International Applicants

The boarding fee is $79,200 for all students, international or domestic.  Additional expenses include the cost of books ($1,000) and health care coverage for international students ($3,000) and optional spending allowances, which vary by family.

ALL international applicants whose primary language is not English are required to take the TOEFL, Duolingo, or IELTS.  You are exempt from this policy if you have studied in an international school in which English is the language of instruction or a junior boarding/day school in the United States for more than two years. Middlesex accepts the IELTS Indicator, TOEFL IBT Special Home Edition, and TOEFL ITP Plus Vericant until regular testing resumes.  Middlesex only accepts scores submitted electronically by the test center.  Our TOEFL code is 8720.

We do not have “minimum acceptable scores.” Typically, the most successful applicants score better than 110 on the TOEFL or 7.5 on the IELTS.  On Duolingo applicants generally score a 135 or higher.  The SSAT median percentile is typically in the mid to high 80s.

We do not have an ESL program.  To be considered for admissions, applicants must already be very proficient in English in all school-related areas.

We do not have targets, quotas, or caps on the enrollment of any students from any one country; geographic diversity within our population is important to us. 

We wanted to assure you that it is a top priority of ours to support each international student’s needs – whether logistical, physical, or emotional – as they navigate a new school environment as well as complex socio-cultural differences. From enrollment to orientation, from student visa application to travel during school breaks, we have a team of dedicated faculty who work particularly closely with our international students and families. In addition to two official SEVIS coordinators, we also have two advisors for our International Student Association (ISA), an affinity group for self-identified international students at Middlesex. We are also thrilled that Middlesex has been selected to host the 4th International Student Conference on February 1st, 2026. If you have any questions about our specific initiatives and programs, please feel free to contact Associate Director of DEI, Ms Starry Zhu (szhu@mxschool.edu). 

Dorms close during Thanksgiving (November), Winter (December/January), and Spring (March) breaks.  See our calendar for specific dates.  Dorms remain open for all long weekends and semester breaks.

It is the family’s obligation to arrange for home stays, guardians, or hosts.  Middlesex may be able to assist families in finding programs.

No, we do not currently have a summer program.
