Introducing International Community School

Welcome to our IB World School.

We are located in central London, across three historic Marylebone sites. This places us at the heart of this incredible city — a city whose energy and dynamism form a huge part of our children’s memories.

But ICS is so much more than its physical location.

To learners aged three to 18 years old, we offer the International Baccalaureate (IB), a gold standard for education built on fifty years of pedagogical research.

The IB promotes levels of academic performance highly valued by the world’s top universities and employers. Across our school, we have created an environment where it can flourish, with students enjoying small class sizes and unrivalled support from faculty and staff. This approach has yielded exceptional results for our students, who have achieved a 34 point IB Diploma average score that ranks ICS among the country’s top IB schools.

We are also proud of the friendly and inviting nature of ICS. Every student benefits from our collaborative and compassionate community, which encourages leadership and self-confidence, as well as friendships that span the world. This is a place where people feel at home, no matter where they are from.

Please contact us if you have any questions or would like more information about ICS. You can also now apply online.

In the meantime, I invite you to find out more about the IB and our curriculum, our approach to learning and teaching, and our vision and mission.

I very much look forward to meeting you.

Best wishes

Our history

ICS was founded in 1979 by the Toettcher family, on the principles of freedom, internationalism, democracy, respect and the rule of law.

Beginning as an English-language school for the children of diplomats and global business people, ICS quickly grew into a fully-fledged academic school.

In the mid-2000s, we introduced the International Baccalaureate to provide the best possible curriculum for our students.

ICS now offers the Diploma Programme (DP), the Middle Years Programme (MYP), and the Primary Years Programme (PYP).

We have an average IB score of 34, placing us in the top 20% of the country for IB results.

Our approach to learning and teaching

Our academic approach is guided by best practice and extensive research, particularly the important work carried out by John Hattie. Hattie emphasised the critical importance of feedback and independent study skills in students.

Carol Dweck, of Stanford University, developed the concept of ‘growth mindset’. When we teach this to our students it has a keenly noticeable effect, helping them dig their way out of even the deepest academic holes.

While our teachers lead classrooms, we employ full roundtable discussions led by the students. This approach empowers students to take control of their learning. In this classroom setting, teachers are conductors of the class, who orchestrate the music of learning.

London attracts people with global ambitions.

It houses some of the world’s greatest exhibitions, is home to diverse cultures, and constantly offers new opportunities to explore.

One-third of new British businesses are started in this global capital city. A financial powerhouse, it also remains at the centre of Britain’s ever-growing creative industries. The city’s schools, universities, workplaces, fashion houses, restaurants, sports teams, architecture and parks are among the best in the world.

We are an urban school, surrounded by beautiful neighbourhoods, with Regent’s Park and Hyde Park just short walks away. And further afield, cities such as Brussels, Paris and Manchester are all under three hours away.

Meet The SLT

The senior leadership team is responsible for the smooth running of the school as well as making sure that it is run in line with its vision and mission. Rose Threlfall, the school head, reports on all school operations and achievements to an education board.

Our wider team has many years of experience in senior school roles internationally and in the UK. We are dedicated to working closely with our faculty, students and parents to create an environment that benefits us all. We also choose to bring a British flavour to the IB curriculum as we teach it at ICS, which helps our students become acclimatised with the country that many continue to call home as they choose British universities.

Rose Threlfall, our Head of School, can be contacted via the contact form and at our 21 Star Street campus.

Pastoral care

The size of our school facilities allows us to provide a personalised approach to education. We strive to elicit passions from our students and then support them in pursuing those. Each student joins a class and has a form tutor who plays a significant pastoral role in their lives.

During the diploma, students also have an academic tutor, who helps students with university applications, and offers further support in the final years of the IB.

Aside from the tutors, our entire staff offers a deeply caring, proactive pastoral approach to our community.

We are not a factory school, we are a community that cares for every one of our students. And indeed, we consider safety and wellbeing to be our number one concern.

Sports, activities and other elements

Our focus on the IB means that co-curricular activities such as sports, learning programmes and other experiences are all used to complement students’ education.

Each year, we run a global classroom programme of events. This programme takes students across the world to learn in entirely new surroundings. That could be in south India, eastern Europe or the southwest of England.
