With impactful teachers, a rigorous education and lasting friendships, the British International School of Washington on Wisconsin Avenue is what Principal Oona Carlin calls “a hidden gem” in Washington.
Though BISW’s name reflects its British heritage, the school warmly welcomes both international and domestic families — including many local to the D.C. area — who thrive in its inclusive, globally minded environment.
“I think it’s really important for us to shout a bit more loudly about what we do and how well we do it,” Oona said. “It’s very British of us to be a bit reserved, but we have so much to celebrate — and I want to make sure more families have the chance to discover what makes BISW so special.”
BISW supports students through every stage of their academic journey — from Early Years (ages 2 to 5) and Primary (ages 5 to 11) to Lower and Upper Secondary (ages 11 to 18). Following the British system, the final year of school is called Year 13, which aligns with Grade 12 in the U.S. At the upper levels, students follow the prestigious IGCSE and IB Diploma Programmes, earning admission to leading universities across the U.S. and around the world. For many families, the ability to remain in one exceptional school community for 15+ years offers both academic continuity and peace of mind.
School Leadership
With more than two decades of leadership across British and international schools, Oona brings a wealth of global experience to her role as principal of BISW, which she joined in 2024. Before arriving in Washington, she spent five years in the Middle East leading two British curriculum schools, following her tenure as principal at Ipswich High School and deputy head at Putney High School — both respected institutions in the U.K.
Earlier in her career, she also taught in Colombia, shaping a perspective that blends academic rigor with a deep appreciation for global education.
“The British education system is so highly valued that it’s allowed me to take it from the U.K. overseas,” Oona said. “It offers the kind of academic depth, critical thinking and global outlook that benefits all students — whether they’re relocating internationally or planning to stay close to home.”
Oona herself was educated in the U.K., earning a degree in biochemistry from Imperial College London and later completing her teaching qualification at Cambridge University.
“I feel fortunate to have had a strong academic foundation,” she added. “It’s a privilege to now help students develop the skills, mindset and global perspective they need to thrive in an ever-changing world.”
That globally minded education has been BISW’s hallmark for 27 years, since its founding in 1998. The school joined Nord Anglia Education’s worldwide family of schools in 2013, further strengthening its international reach and collaborative opportunities.
A Creative, Welcoming, Academically Rigorous Environment
Through three factors — British heritage, a personalized approach to learning and an international focus — BISW offers a unique academic experience that’s different from other schools in the area. The students at BISW, who range in age from 2 to 18, represent over 70 nationalities. They’re well-rounded, with interests ranging from music to art to the sciences, and everything in between.
Daya, in Year 9, wants to become a doctor when she grows up and plans to combine that with classical piano to help “heal people completely.”
“I feel like BISW really understands and supports my goals to become a doctor,” Daya said. “With the help of my parents and my teachers, I have started to get involved in medical-related activities. I also volunteer and lead classical piano performances at hospitals, rehab centers and other programs.”
BISW collaborates with multiple leading institutions like MIT and the Juilliard School. Its global program with MIT inspires students to look beyond individual subjects, sparking curiosity through a hands-on interdisciplinary approach to problem-solving, guided by the world’s leading STEAM institution. Through the Juilliard partnership, BISW enhances its drama and music programs, while promoting creativity, teamwork and resilience among students of all ages.
Year 13 student Eva knows what it means to adapt. She just finished her first year at BISW, having attended several schools across different countries, including a move to Malaysia.
“Being in a school like BISW, where international experiences are the norm, makes those transitions so much easier,” she said. “It can be daunting to walk into a new school building with unfamiliar faces and spaces, but here you feel welcomed right away. People are open, inclusive and genuinely want to get to know you.”
Lada, Year 13, spoke about the strong relationships and consistent support she’s experienced throughout her time at the school.
“What I love most is that BISW truly feels like a second home,” she said. “The teachers really know you, and the friendships you build here run deep. There’s a strong sense of community that makes every year feel connected.”
Recent Renovations
Speaking of buildings, BISW has undergone renovations in recent months. There is a new outside learning space for nursery students, and the school is currently developing a new “Knowledge Hub” — a dynamic, whole-school environment designed to foster collaboration, research and creativity.
“For our Primary Students, we’ve just created what we’re calling the ‘DREAMS Lab,’ where they can do their science and technology work,” Oona said. “As a Nord Anglia school, we have an MIT collaboration, and many of the hands-on projects our students explore — even at a young age — are inspired by real-world challenges from MIT researchers. It’s all about helping students become inquisitive problem-solvers from the very start. The space itself is designed to spark imagination.”
Respected Teachers
In addition to its state-of-the-art campus, BISW’s greatest strength may be its teachers — deeply respected by students for their individual support and lasting impact. Many students shared stories of educators going above and beyond to help them succeed, both academically and personally.
Sofia, Year 12, arrived at BISW after several school moves that had disrupted her learning. One of her teachers gave up their lunch period to help her study and review material for exams. “I appreciate her for that,” Sofia said.
Others spoke to the way BISW teachers help students think more deeply and grow as individuals. “English has been especially transformative for me,” said Muhd, a Year 13 student. “It’s helped me see the world in new ways and even supported my personal and spiritual growth.”
Kavan, Year 11, shared a similar perspective. “My physics teacher has been extremely supportive,” he said. “She’s played a big role in helping me build confidence in the subject.”
That same personalized guidance extends beyond the classroom. “I’ve spoken with my university counselor a lot throughout the year,” said Paul, Year 13. “I’ve been to every university visit the school has offered — it’s been incredibly helpful in planning my next steps.”
Beyond graduation, BISW students credit the school with preparing them for what’s next.
“My brother’s transition to university was a lot smoother because BISW helped him build strong time-management and organizational skills,” said Callum, Year 13. “It’s a smaller environment, so it’s easier to share ideas, work in groups and really understand different perspectives.”
Looking Ahead
As the school year begins, BISW will take part in Georgetown’s Art All Night, a free annual arts festival that brings together local artists, businesses and performers.
“We’re proud to be one of the lead sponsors of this year’s Art All Night event,” Oona said. “It’s a wonderful way for us to support the Georgetown community and share the creativity of our students with a wider audience.”
BISW will feature a student art exhibition and live performances throughout the evening, showcasing the breadth of talent within the school’s vibrant arts program.
“We’re proud to be a longstanding part of the Georgetown community,” Oona added. “Events like Art All Night give us the opportunity to celebrate our students’ talents while deepening our connection to this vibrant neighborhood.”
