Marymount International School Review 2026: Small, global, IB focused, with London boarding

Families comparing schools should be aware that Marymount does not sit neatly inside the mainstream GCSE and A level comparison ecosystem used for many England league table conversations. there are no published GCSE or A level performance measures to report for the school, and it is not ranked in the FindMySchool GCSE or A level tables. That does not imply weakness, it reflects the limits of comparability for a small, international IB school within standardised domestic headline measures.

What can be stated with confidence is curriculum intent and delivery quality. ISI reports that the curriculum covers the required areas within the International Baccalaureate framework and that pupils make good progress, supported by focused preparation and generally effective questioning and feedback, although consistency in questioning and written feedback was flagged as an area to tighten.

Marymount’s academic spine is the IB, with Middle Years Programme style breadth through the mid school years and the IB Diploma Programme in sixth form. The most useful implication for parents is practical: the IB rewards sustained coursework habits, writing, and organised time management, with creativity and service embedded into the senior experience through IB requirements.

ISI’s evidence points to confident classroom practice and purposeful learners. Teachers prepare lessons carefully, most use effective questioning, and feedback supports progress, with the school encouraged to make that quality more consistent across subjects.

For students who arrive with English as an additional language, the inspection notes appropriate support to develop fluency and confidence. This matters at IB level, where language precision and extended writing can quickly become the limiting factor even for very able students.

For a school of this type, “next” is overwhelmingly university, often with international pathways. The school’s published university placement page lists destinations across the UK and overseas, including examples such as Imperial College London, King’s College London, SOAS, University of Toronto, and institutions in Japan such as Keio and Sophia.

Oxbridge entry is not a dominant headline in the available destination data, but it is present. In the recorded measurement period here, there were five Oxford and Cambridge applications, with one offer and one acceptance, both to Cambridge. A realistic implication is that Marymount supports highly ambitious applications, but families should treat Oxbridge as one lane among several, not the defining route.

ISI also notes that careers education is effective in building employability understanding, while recommending further development to give pupils broader insight into the range of further education and work options available.

Admissions are described by the school as rolling, including mid year entry when space allows, which is common for international schools with mobile families. For standard Year 7 entry, the school sets out a calendar pattern that includes an assessment day in November, first round offers in mid December, scholarship applications in February, and an acceptance deadline in March.

For September 2026 entry into Year 7, the school publishes a specific assessment day date: Friday 14 November 2025. Scholarships are also positioned as part of the admissions picture, with awards available for girls applying at Year 7 and Year 12 entry points across a range of disciplines.

Because the school is independent, there is no local authority coordinated application route and no catchment style distance allocation to rely on. The practical step for families is to engage early, confirm space availability, and understand whether they are seeking day, weekly, or full boarding, since those pathways shape availability and cost.

FindMySchool users shortlisting Marymount alongside other independent or state options will usually benefit from saving the school and tracking key dates in one place, especially if you are also applying to schools with fixed local authority deadlines.

Pastoral support is a core selling point for many international families, and the inspection evidence backs up a structured, safety conscious approach. ISI records that staff and governors take safeguarding seriously and that recruitment checks are completed with outcomes recorded before individuals start work. Standards relating to safeguarding were judged to be met at the 2025 inspection.

In day to day culture, the inspection emphasises respect, consideration for difference, and a PSHE and relationships and sex education programme that supports pupils’ physical and mental health and wellbeing. For parents, the implication is that wellbeing is treated as a planned curriculum strand rather than an informal add on.

Marymount’s co curricular life is strongest where it links to the school’s international identity and performing arts culture. The published arts programme includes an annual school production with a real backstage pathway (lighting, sound, technology, set, costume, make up, prop design), with recent titles listed as The Little Mermaid (2024), Legally Blonde (2022), High School Musical (2021), Urinetown (2020), and Hairspray (2019). That is a concrete example of breadth: students who do not want the stage can still build confidence and technical skill in production roles.

Music is described with specific ensembles, including Chamber Choir, Liturgical Choir, Orchestra, and Rock Band, supported by specialist peripatetic teaching. For IB students, this matters because creative commitments have to be balanced with heavy assessment loads, and a structured ensemble calendar can help students plan rather than over commit.

For clubs, the school’s own handbook style information cites activities such as Writer’s Circle, Science Club, Model United Nations, Orchestra and Choir. Model United Nations also appears repeatedly in school communications as a signature experience, including conference participation and trips.

Sport is presented with seasonal structure. Examples include volleyball, soccer, cross country, basketball, tennis, strength and conditioning, and varsity badminton. The key implication is that sport is available as a consistent routine for wellbeing, even for students who are not high performance athletes.

The published school day begins at 8.30am, and term date notices show classes ending at 4.00pm on standard days, with some term end early finishes. Transport is unusually well specified for an independent day and boarding school, with route zones and typical timings: morning pick up commonly between 7.00am and 7.30am depending on location, a standard departure at 4.10pm, and a later departure at 6.10pm for after school activities.

The school describes its location as in Kingston upon Thames, with Wimbledon used as a nearby transport hub; it also states that routes are reviewed annually to reflect family needs. Wraparound care in the usual primary school sense does not apply, but the late transport option effectively functions as a practical extension for students staying for co curricular commitments.

Fees & Financial Aid

For 2025 to 26, published tuition for a day student is £37,140 per year. Weekly boarding totals £60,180 per year, and full boarding totals £62,880 per year, with fees stated as inclusive of VAT. One time charges include an application fee of £240, and acceptance fees of £1,800 for day places or £3,000 for boarding, plus a refundable deposit of £300 for day or £750 for boarding.

Fee inclusions are clearly listed: full IB tuition, textbooks, laboratory fees, most classroom materials, key educational trips, personal accident insurance for serious injury, lunch, English as a Second Language support, and learning resources. Families should still budget for extras that are billed separately, including IB examination fees, some trips, and other disbursements, which the school indicates may be invoiced during the year.

On financial support, the school explicitly states that bursaries may be awarded on the basis of need and potential to benefit, with funds described as limited, and scholarship programmes available at Year 7 and Year 12 entry points. The practical message is to raise bursary intent early, since timing can matter for assessment and award decisions.

Boarding

Marymount is a London area boarding option, which is relatively rare, and it offers flexible modes: full, weekly, and flexi boarding. For many families, the distinctive value is not tradition for its own sake but logistics: an international school with boarding that keeps access to London’s cultural and academic resources.

ISI notes that boarding accommodation is centrally positioned on site and that houses are well maintained and welcoming, creating a secure and pleasant environment for living and learning. The school’s own boarding description highlights communal lounges, study areas, and gardens, with weekend activities and excursions framed as part of the normal offer.

• IB intensity and breadth. The IB suits organised, reflective students who can sustain effort across multiple subjects. Those who strongly prefer a narrower sixth form focus may find the IB workload demanding.

• Small school dynamics. Close relationships are a strength, but a small year group can feel socially tight. For some students that is reassuring; for others it can feel limiting if friendship groups shift.

• Boarding fit varies by family. Flexi and weekly options reduce the all or nothing feel of boarding, but boarding still requires maturity around routines, device use, and independence.

• Careers breadth is still developing. ISI’s recommended next steps include strengthening the careers programme to broaden insight into post school options beyond the most familiar university routes.

Marymount International School suits families who want a small, internationally oriented girls’ school with a consistent IB pathway and a boarding option within reach of London. The best fit is a student who enjoys discussion, writing, and global perspectives, and who will use co curricular opportunities such as theatre, music, and Model United Nations as real extensions of learning. Families should weigh the academic intensity of the IB and the social realities of a small cohort, then focus on admissions timing and boarding type, since those practical decisions shape the experience as much as the curriculum.
