International School Aberdeen (ISA) is an independent, co-educational day school at Pitfodels House, North Deeside Road, Aberdeen, AB15 9PN. The school describes itself as an IB World School on its website. Its senior programme leads to the International Baccalaureate (IB) Diploma, a two-year school-leaving qualification used for university entry.

Compare Robert Gordon’s College, in the city centre at Schoolhill, if you are considering Scottish qualifications. It offers National qualifications and Highers, the senior qualifications commonly used for university entry in Scotland. Compare the curriculum and journey before the headline fee.

La Petite French School d’Aberdeen is hosted on ISA’s campus as a home-language programme. This may help a child maintain French alongside their main education; it is not a separate senior school-leaving qualification.

Who it is for

ISA is a good option for families who want English-medium schooling from preschool to Grade 12 and an IB Diploma route in the final years. For a family expecting another international move, ask how the proposed year group matches the child’s previous and likely next school. An international qualification does not guarantee that every mid-course transfer will be straightforward.

Compare Robert Gordon’s if your child wants to study Highers. Choosing ISA does not rule out Scottish universities: the relevant question is whether the IB subjects and grades meet the requirements of the intended degree. If boarding is essential, compare Gordonstoun in Moray; that would also mean choosing a different location and residential arrangement.

Campus and the school day

The campus page describes a woodland site near Cults with classrooms, a pool, pitches, a theatre and a climbing wall on one campus. Test the journey along North Deeside Road at your expected drop-off and collection times before deciding where to live.

The school lists Encore! wraparound care from 7.15am until 6pm. The full span is not included in tuition: the fee information includes the 3–4pm session, with extended care charged separately. Middle and High School fees include a school Chromebook.

How the years are organised

The school divides its provision into Preschool (ages 3–5), Elementary (5–11), Middle (11–14) and High School (14–18). The programme culminates in the IB Diploma. Ask which subjects are available and how the school advises pupils on university entry requirements; the qualification name alone does not establish whether a particular combination is possible.

High School tuition includes IB examination fees, so those should not be added again to the published annual fee.

How a child actually gets in

Applications are made online through the admissions page. The published charges are £50 per child to apply, £600 registration on first admission, and £300 registration for each subsequent year for returning pupils. Ask admissions about the assessment process and availability in your child’s year group before making relocation commitments.

As of 3 September 2026, the open-days page advertised Friday 11 September 2026, 12.30–2.30pm. Individual tours are also offered through the year; use the page to arrange a visit.

Fees and additional costs

The fee schedule gives these annual tuition fees for 2026–2027, including VAT. They cover lessons, campus facilities and Encore! from 3–4pm. The Scottish year labels in parentheses help families compare stages: Primary 1–7 are primary-school years, and S1–S6 are secondary-school years.

  • Kindergarten and Grade 1 (Primary 1–2) — £13,500
  • Elementary Grades 2–5 (Primary 3–6) — £18,360
  • Grade 6 (Primary 7) — £19,680
  • Grades 7–8 (S1–S2) — £21,000
  • Grades 9–12 (S3–S6) — £21,000, including IB examination fees

For preschool, the reviewed information lists Encore+ wraparound options at £5,340 and £9,880 a year, including lunch. These are additional-care figures, not a confirmed preschool tuition total. Request the core tuition fee and the exact hours covered by the option you need.

The schedule lists transport at £800 for the first child and £650 for each subsequent sibling. Confirm the billing period and route. Other Encore! options are listed at £1,475, £1,840 and £2,100 a year for three, four and five days, respectively. Ask which sessions those amounts cover before calculating the total for your working week.

The admissions page advertises scholarships for August entry with a 10% fee discount. As this guide was reviewed in September 2026, ask which future intake the offer applies to, its eligibility conditions and deadline before including a discount in your budget.

Our take

Choose ISA if you want English-medium day schooling, an IB Diploma route and a campus near Cults that works for your daily journey. Its £21,000 High School tuition for 2026–2027 includes VAT and IB examination fees, but registration and some daily services add to the budget.

Compare Robert Gordon’s College if Highers and a city-centre location fit your child’s plans better. The decision should follow the child’s subjects, likely next move and commute; the length of an Aberdeen posting alone does not decide which school is right.
