Testing, financial, legal, and other factors

To meet United States' government regulations as well as Principia Upper School’s academic and other requirements, international students and their families should be aware:

  • During the application process, each student’s family will incur expenses related to taking the TOEFL English-language test and fulfilling U.S. visa requirements (including a TB test, visa application, interview, etc.)
  • Transportation between your home and Principia is the responsibility of the student’s family.
  • Although Principia offers financial aid to qualified students, this amount may not entirely cover the cost of tuition, room, and board—and a student’s family is responsible for payment of the balance.
  • All students need funds for personal items, school supplies, school uniform and casual clothing, and occasional social activities. Principia cannot and does not cover such costs.
  • Be sure to submit a financial aid application and supporting documents at the same time as the admissions application.
