Understanding Boarding School Entry Ages


How year groups, grades and entry points are named in the UK, US, Canada, Australia, New Zealand, Ireland and Switzerland, and why you should confirm a school's own minimum boarding age.

Last reviewed 17 October 2026

"What age can my child board?" has no single answer. Countries name school years differently, start counting from different ages, and leave boarding minimums to individual schools. A child described as "Year 9" in England, "Grade 9" in the United States and "Year 9" in New Zealand is in a different place in each system. This guide explains the vocabulary and the common entry points, and points to the places where an official age rule exists. Wherever a figure is not published by an official source we retrieved, it is left out and you are told to ask the school.

Why entry points cluster

Boarding schools take new pupils most easily where the school itself changes stage: from primary to secondary, from lower to upper school, or into the final two years before leaving. Cohorts are formed at those points and pupils joining then are not the only newcomers. Joining at other times is often possible but depends on space and on the school's own policy.

United Kingdom

GOV.UK describes the national curriculum in England by key stage: Reception (ages 4 to 5), Key stage 1 (Years 1 to 2, ages 5 to 7), Key stage 2 (Years 3 to 6, ages 7 to 11), Key stage 3 (Years 7 to 9, ages 11 to 14) and Key stage 4 (Years 10 and 11, ages 14 to 16), where most children take GCSEs in Year 11. The sixth form (Years 12 and 13) follows. Many independent schools describe their own entry points in these terms, such as joining in Year 7, Year 9 or the sixth form, but each school sets its own and some use different names. Scotland and Northern Ireland have their own year naming and stages, so check each school's description.

For overseas children, GOV.UK's Child Student visa page states, as published on the date accessed, that applicants are between 4 and 17 years old, and that applicants aged 18 or over should apply for a Student visa instead. It also says the permitted length of stay depends on age when applying: for under 16s, the course (up to 6 years) plus 4 months, and for 16 and 17 year olds, the course (up to 3 years) plus 4 months. Check the page for current wording before applying.

United States

The Department of Homeland Security's Study in the States site, which covers the Student and Exchange Visitor Program (SEVP), describes the F-1 rules for kindergarten to grade 12 by grade rather than by age. As published on the date accessed, public schools can be certified only for grades 9 to 12 and F-1 students there are limited to 12 months in total, while private schools can be certified for any or all of their K-12 programmes with no time limit on attendance. This means that boarding schools, which are private, generally have no federal limit on how long an F-1 student may attend.

Most US boarding schools describe entry points by grade, commonly grades 9 to 12. Some also take students in earlier grades or accept a postgraduate (PG) year, a further year after completing high school. Terminology and eligibility for such a year vary, and Study in the States does not define it, so ask the school how it describes the year and whether it is permitted under the student's visa category.

Canada

Canadian schools use grade numbers, and structures vary by province. IRCC's page on minors gives age-of-majority figures that matter for custodianship: 18 in Alberta, Manitoba, Ontario, Prince Edward Island, Quebec and Saskatchewan, and 19 in British Columbia, New Brunswick, Newfoundland and Labrador, the Northwest Territories, Nova Scotia, Nunavut and Yukon. It states that minors under 17 must either travel with a parent or legal guardian or have a custodian in Canada, and that for those 17 or older a custodian is optional although an officer may ask for one. Check the page for current wording.

Australia

Australian schools use year levels, and the names of the final stage differ between states. A state's certificate authority, such as NESA in New South Wales, publishes syllabuses by stage. Because no retrieved official page set out Australian year levels or boarding minimum ages for this guide, ask each school for its own entry points and boarding minimums.

New Zealand

NZQA states that NCEA is worked through at Levels 1 to 3 in Years 11 to 13 at school, so the senior school begins at Year 11 in the New Zealand system. Immigration New Zealand's Fee Paying Student Visa page says that a child under 10 who is not living in an NZQA-approved school hostel must be accompanied by a parent or legal guardian and live with them while studying. Check that page for the current rule.

Ireland and Switzerland

Irish schools use First Year to Sixth Year, with the Leaving Certificate at the end of Sixth Year, and Swiss schools vary by canton and by the language of instruction. Because no official page for either could be retrieved for this guide, no age rules are given here. Ask the school what its first year of entry is and what its minimum boarding age is.

Minimum boarding ages are set by schools

Even where a child can enrol, a boarding house may set a higher minimum age for boarding than for day attendance. The only reliable answer is the school's own published policy. Ask also whether younger boarders live in separate accommodation, how many pupils are the same age, and whether weekly or flexible boarding is offered first.

Check before you decide

  • What are the school's entry points by year group or grade, and what does it call them?
  • What is the minimum age for boarding, and is it the same as for day attendance?
  • Can a child join part-way through a year, and what happens to the course already begun?
  • If joining from another system, how does the school decide which year to place the child in, and can that be reviewed later?
  • Are there additional visa age rules for the country and student category you are considering, and where are they published?
  • Is a postgraduate or extra final year offered, and does the student's visa category allow it?
