US high school: public school or boarding
.jpg)
US high school is American secondary school: four years (9th to 12th grade), at a public school with a host family or at a boarding school on campus.
This guide compares both models, SAT/ACT, and the curated schools. The boarding definition is in what boarding school is. The program is in high school abroad.
How does high school work in the USA?
American high school divides the four years into progressive stages. In 9th and 10th grade, the student completes core subjects (English, math, science, and history). In 11th and 12th, electives and AP courses start to carry direct weight in the university application.
GPA (Grade Point Average) is the average across the four years, on a 0 to 4.0 scale, and enters the application together with SAT or ACT, extracurriculars, and recommendation letters.
- IB Diploma: six subjects in thematic groups, with TOK, Extended Essay, and CAS. Breadth and depth at the same time.
- A-Level: specialisation in 3 or 4 subjects, with depth similar to a first university year.
- American high school: a schedule built by the student with electives. More flexible, with AP courses as a competitive edge.
The IB Diploma preserves thematic breadth until age 18, which helps students who have not yet chosen a field.

What is the difference between public high school and boarding school?
The choice between public school and boarding school defines the student's life structure, not only the curriculum.
Public high school with host family
The student lives with a local host family and attends the community school. Integration is real: classes with American peers and participation in local sports teams.
The host family model accelerates English fluency through full immersion outside the school environment.
Private boarding school
The student lives on campus, with classes, sports, supervised study, and dormitory life integrated. University preparation is more intense: smaller classes, direct access to tutors, and SAT/ACT testing centres on campus. Families choose this format when they want controlled academic structure and 24-hour support.
The comparison between boarding school and conventional high school covers the impact of each model on GPA, university applications, and autonomy. Both formats require an F-1 visa, issued via the US consulate after the I-20 acceptance form.
How do SAT, ACT, and Advanced Placement work?
SAT and ACT are standardised tests that measure academic readiness and enter university applications directly. AP courses, in turn, are high school subjects assessed by the College Board that can already earn university credits.
| Assessment | What it measures | Format | Scale | Weight in applications |
|---|---|---|---|---|
| SAT | Reading, writing, and math | Digital sections via Bluebook | 400-1,600 | Main quantitative criterion in US applications |
| ACT | English, math, reading, and science | Independently timed sections | 1-36 | Equivalent to the SAT; accepted by the same universities |
| AP | Mastery of a specific subject | Annual exam in May; scale 1-5 | 1-5 | Score of 3+ earns credit at many US universities |
The College Board offers 42 AP courses in 2025. In May 2025, more than 6 million AP exams were administered, including more than 3.8 million in the digital format via Bluebook, according to the College Board.

How do applications and the F-1 visa work?
The F-1 visa is the US student visa for full-time academic programmes. The issuance process follows sequential steps, and it is wise to start at least six months before the academic year begins (August or September).
The main steps, according to the U.S. Department of State:
- School records and English test: submission of grades from the last two years and a TOEFL or Duolingo English Test result for the school's initial review.
- Admissions interview: held online for international applicants; focus on motivation, academic path, and interest in the programme.
- Acceptance letter and I-20 form: document issued by the school that confirms enrolment and is required to start the consular process.
- DS-160 form and SEVIS fee: completion of the visa form on the US consular portal and payment of the SEVIS fee (Student and Exchange Visitor Information System), according to USCIS.
- Consular interview: scheduled via the US consular portal; the student presents documentation, the I-20, and proof of funds.
Boarding school daily life often differentiates international student performance from the first semester. F-1 rules for work during high school include campus employment allowed by USCIS.
