Wellbeing & support	Wellbeing & support
Social & emotional learning	Social & emotional learning Wellbeing is an integral part of ACS Cobham, with a dedicated wellbeing team providing a safe, healthy, and respectful environment. The Pastoral Team works to support students' health, wellbeing, academics, and everyday life, offering both individual and group support and coordinating with families. Counsellors collaborate with parents and teachers to identify needs and may refer to external professionals when appropriate. PSHE is embedded across the curriculum to develop compassionate, confident, and responsible individuals, reinforced through advisory structures and whole-cohort activities. Student wellbeing ambassadors and a proactive wellbeing program ensure student voices are heard in campaigns and initiatives, while a Medical Centre on site offers medical support for physical and mental health needs. DEIB and inclusive practices run throughout, and boarding welfare is supported by a dedicated team and wellbeing initiatives.	Social & emotional learning Marymount International School London places happiness and wellbeing at the heart of learning, and social-emotional development is integral to its pastoral life. Advisor Groups ensure every student is known and cared for, with a dedicated faculty member guiding emotional and study skills and providing a safe space for discussion. Heads of Year construct an age-appropriate Advisor curriculum to support social and emotional learning and development, while all students receive a Wellbeing Booklet with tips, resources and contacts. A counsellor is on campus three days a week to provide confidential support, and staff may refer students as needed. The Senior Mental Health Lead coordinates mental health support in collaboration with the School Nurse, and staff are trained as Mental Health First Aiders to respond in emergencies.
Special educational needs (SEN)	Special educational needs (SEN) ACS Cobham provides Special Education Needs and Disability (SEN/D) provision in line with the organisation's SEN/D policy. The policy defines SEN as difficulties that require extra educational provision and identifies four broad areas of need: communication and interaction, cognition and learning, social, emotional and mental health, and sensory and/or physical needs. It promotes inclusive practice, removing barriers to learning, high-quality teaching, early identification, and regular review with family involvement. Service provision follows a multi-tier system (MTSS) with dedicated SEN staff, integration into mainstream classes, and a mix of universal, targeted, and specialist supports; on-site provision and access to external specialists are coordinated by case managers. Regular Student Services Teams, staff training, and the use of assistive technologies support learning, with additional supports determined by individual needs.	Special educational needs (SEN) The School offers a wide range of support for students for whom English is an additional language. The SEN definitions recognise learning difficulties and other disabilities, including conditions that may affect the ability to access the curriculum. For students with identified needs, an Individual Education Plan (IEP) is prepared in consultation with parents and the student, and an Action Plan or Collaborative Action Plan may be used to address educational, behavioural or pastoral concerns. A provision map documents the supports available and informs teachers of the student's plan. If a student has an Educational Health and Care Plan (EHC plan), the School will collaborate with the local authority to deliver the provision, and additional services may be funded by the local authority where applicable. The Learning Resource Centre (LRC) staff liaise with teachers to differentiate instruction and monitor progress as part of the wider welfare and pastoral process.
English as an additional language	English as an additional language The EAL programme helps students achieve proficiency in academic English to thrive in a global community and succeed in AP and IBDP courses. The programme is personalised for each learner and includes Intensive English Courses with small-group instruction led by EAL specialists, initially up to three lessons per day. Academic Language Development provides in-class support for math, science, and humanities to help students analyse complex texts and write effectively in English. A dedicated case manager monitors each learner's progress, using the WIDA framework to benchmark growth across listening, speaking, reading, and writing. The EAL approach uses Universal Design for Learning to ensure accessibility, with boarding offering additional homework support and opportunities to maintain home languages; IB Diploma students can pursue self-taught literature options toward the IB Bilingual Diploma. Graduates routinely go on to top universities in the UK, US, and elsewhere.	English as an additional language English is the language of instruction; all students study either Language & Literature or Language Acquisition in the IB programme. Students with limited English receive initial language-support (ELD) to enable effective learning across subjects, with schedules designed to support this provision. All students (except those temporarily developing English) are required to study at least two languages, and those in English Language Acquisition or ELD may audit English A classes when appropriate. English Language Development is delivered in Grades 6-8 (three levels) and Grades 6-10 with defined hours; additional language support is provided as needed to reach proficiency. The school also offers Mother Tongue Instruction or support in languages such as Chinese (Mandarin), French, German, Japanese, Korean and Spanish, with further language options pursued through DP arrangements if numbers permit.
Mental wellbeing	Mental wellbeing Mental wellbeing is supported as part of the school's overall wellbeing program. A central wellbeing team and dedicated pastoral staff create a safe, healthy environment founded on mutual respect and trust. The Pastoral Team strengthens health, wellbeing, academics, and life skills, with both individual and group support and collaboration with families. Several full-time counsellors work with parents and teachers to address needs, with external referrals used when necessary. PSHE education promotes resilience, digital citizenship, healthy relationships, and personal development across year groups, guided by a proactive wellbeing program and student wellbeing ambassadors. The Ready to Thrive initiative provides safe spaces and wellbeing hubs, and there are wellbeing ambassadors and student voice channels to influence wellbeing campaigns. The school operates a Medical Centre with nurses and links to local care to support physical and mental health, and boarders receive 24/7 welfare support, including the Lotus Project for regular one-to-one coaching. DEIB is embedded across the community, ensuring inclusive support for neurodiversity and mental health needs.	Mental wellbeing The Health and Wellbeing Policy commits the school to promoting physical and mental health and provides a structured approach to mental health, including early intervention and involvement of staff, parents and the community. A registered nurse and a qualified counsellor deliver health and wellbeing services on site, and the school is in partnership with a local GP surgery. The Mental Health Lead, supported by the School Nurse, leads on mental health matters, identifies issues, facilitates referrals, and helps develop whole-school approaches to wellbeing; mental health first aid training is available for key staff. The school is a MOSA member to ensure high-quality care, and students are listened to with respect for privacy, dignity and involvement in decisions affecting their wellbeing. Health education is coordinated with PSHEE staff to keep wellbeing information current and relevant.
Safeguarding	Safeguarding ACS Cobham follows the Safeguarding & Child Protection Policy (publication date September 2025) to keep children safe and secure in ACS schools. The policy affirms that safeguarding is everyone's responsibility and aims to provide a safe, welcoming environment where concerns can be raised and addressed promptly. It aligns with statutory and local guidance, including Keeping Children Safe in Education, and sets out roles and responsibilities for staff, trustees, and leadership. The policy enshrines a zero-tolerance approach to sexual violence and harassment and emphasizes early identification of risk, collaboration with parents and external agencies, and high-quality safeguarding practice across the school. It also covers reporting and responding to safeguarding concerns, the involvement of the Designated Safeguarding Lead (DSL) and Local Authority processes, and coordination with local safeguarding partnerships. All staff are required to uphold safeguarding duties, with on-site and partner resources used to support children in need or at risk.	Safeguarding Safeguarding and the welfare of students are paramount. The school has a designated safeguarding lead (Ms Annah Langan), deputy safeguarding leads (Ms Paula Horton and Ms Annie Plumridge) and safeguarding governors (Ms Cristina Serrano and Ms Niamh Green). The school works with Kingston and Richmond Safeguarding Children Partnership (KRSCP) to promote safety. Should concerns arise, referrals can be made to Children's Services via the Single Point of Access, and there are emergency contacts including the police (999) and CEOP for online safety concerns. This framework ensures clear reporting channels and safeguarding governance.
