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.
