Admissions
Admissions
1. Enquiry — Find out what ACS Cobham offers in terms of curriculum and facilities to ensure it is the best fit for your child. We recommend visiting for an Open Day or Personal Tour to explore the campus, meet our academic staff and discuss admissions with the team. You can make an enquiry to begin the process. We operate a rolling admission process, with applications accepted year‑round and students may start at any point in the academic year, subject to availability.
2. Application — You can apply all year around as long as your child has the right to study in the UK. Each application is accompanied by a non‑refundable application fee paid online.
3. Review — Once your online application is completed, it will be assessed by the Admissions Team, taking into account all information provided. We will contact you if any additional documents are required and inform you of the outcome as soon as we can.
4. Admission — If your application is successful, we will contact you with an offer of a place for your child. To secure the place, a non‑refundable enrolment deposit is required, which is set against the second semester tuition/boarding fees. For more details of application fees, deposits and tuition costs, see Fees. Should your child's application be successful, but the grade or programme applied for is at capacity, your child will be waitlisted. When a place becomes available, we will contact you immediately to complete the rest of the admission process.
5. Welcome — Our team will provide you with all the necessary information (cafeteria, transport, school platforms, subject selection, visa compliance, etc.) prior to the first day of school to ensure a smooth start for everyone.
Admissions
1. Rolling admissions and space availability. Marymount operates rolling admissions and may accept applications throughout the school year, subject to space availability. Families should contact the Admissions Team before beginning the online application to learn about current space and entry options. This helps families plan for potential mid-year admissions.
2. Online application and initial steps. Begin the online application and plan to save your progress as you go. Upload documents (passport, visa, school records) and electronically submit the necessary recommendation forms to your daughter's current school. After the completed application is received, a member of the Admissions Team will be in touch to discuss next steps.
3. Assessment process by grade. The admissions process is holistic and rigorous, with assessments tailored by grade. Grade 6 entry (Year 7) includes an assessment day with an online aptitude test, small group activities, and an individual interview. Grades 7–10 entry involves written tests in Maths and English and an interview with a senior academic team member (online or in person). Grade 11 entry (IB Diploma Programme) involves written tests in Maths and English and an interview with the IBDP Coordinator; entry to Grade 12 is considered on a case-by-case basis, with a reference requested from the current school for all entry grades.
4. Offers, documentation, and visa steps. Offers of admission are extended following assessment and may be conditional upon receipt of official records and validation of documents. The school reserves the right to reconsider an offer if new information arises. Overseas applicants must satisfy UKVI visa requirements; the visa process is the responsibility of the applicants and their parents.
5. Language, SEN considerations, and grade placement. Students whose first language is not English are assessed on entry to determine appropriate English language development support (ELD/English B). If special educational needs are identified, a meeting may be arranged to discuss adjustments and services (Learning Resource Programme) and any related costs; the school may place students in the most appropriate Grade based on age and ability.
Scholarships
Scholarships
Bursaries are offered to students with exceptional personal and academic potential who would benefit from an ACS education but whose family circumstances mean that affording full school fees cannot be met. The ACS bursary programme has been suspended for the academic year 2026/2027; details for 2027/2028 will be published in 2026. Applicants must be a UK resident, live within the school's bus catchment area, and have the right to remain; each bursary application is assessed individually. Bursary awards can cover up to 100% of tuition for up to seven years and may include additional costs; the amount is calculated after assessing income and financial assets, with annual review. All bursaries are means-tested.
Scholarships
Scholarships are available for Grade 6 (Year 7) and Grade 11 (Year 12) entry. Scholarships in a range of disciplines recognise excellence, effort and engagement and provide opportunities to extend learning in specific disciplines. For Grade 6 entry, MYP scholarships include Academic (by invitation after grade 6 entrance assessments), Visual Arts and Design, Performing Arts (Dance, Drama or Music), and Sports. For Grade 11 entry, IBDP scholarships include Academic, Arts, Sports, Service, and All-Rounder. Applicants wishing to apply for a scholarship should indicate this on their application form; further detailed information is provided upon expression of interest.
Bursaries are means-tested and available in a limited number each year. All applications are confidential and considered on a case-by-case basis; a full statement of financial circumstances with supporting documentation is required and reviewed by a third party prior to any award. The bursary fund is finite, and awards are at the Headmistress and Governors' discretion and subject to annual review. Indicate on the application if you wish to be considered for a bursary; the Business Office will follow up. The bursary assessment runs concurrently with the entrance process and does not affect the testing outcome or placement. Written notification of bursary outcomes is provided simultaneously with a placement offer.
