A new school with
a very clear idea.
Bloom International School is an IB candidate school* for the PYP in Phnom Penh, welcoming children from Early Childhood to Grade 12 — currently offering classes from Early Childhood to Grade 5. It is a private institution fully authorized by the Royal Government of Cambodia through the Ministry of Education, Youth and Sport.
Located on a spacious 5,000 m² campus in the Toul Sangke district, in the heart of Phnom Penh, Bloom serves a diverse community of students representing various nationalities. The school follows the world-renowned IB Primary Years Program (PYP), delivered entirely in English by highly qualified teachers.
To ensure a well-rounded and locally relevant education, the curriculum is complemented by Khmer Language, History, and Culture classes. This holistic approach helps students thrive both academically and culturally in Cambodia.
BIS is committed to multilingualism as a foundation for educational excellence. We offer five languages as part of our curriculum: English, Khmer, Spanish, French, and Mandarin Chinese, enabling students to pursue multiple internationally recognized qualifications.
Our teaching methodology is personalized, with individual monitoring to support each child's unique development and progress. We place strong emphasis on core values and character education, and we are dedicated to helping every student reach their full potential.
Six ways to get to know us
A warm welcome to Bloom International School.
Welcome to Bloom International School, a private day school serving students from age three through Grade 12 — currently offering classes from Pre-K to Grade 5. I hope this website gives you a clear insight into what makes our teaching and learning environment so special, and how we've built a strong reputation not only in academics but also in creativity, multilingualism, and the holistic development of every child.
At BIS, our school culture is grounded in five core values: respect, responsibility, kindness, justice, and giving the best of oneself. These values are instilled in students from the moment they walk through our doors. We want our children to grow up understanding that life is not just about following rules, but about doing what is right based on their own values and integrity in the world around them.
Our students and staff take great pride in our school. We are confident that we offer the highest level of care and the most personalized education a child can receive.
As a team, we are dedicated to continually building a school of excellence, where children are motivated and challenged, where learning is engaging and enjoyable, and where every child is truly seen, supported, and inspired to reach their full potential.
We see BIS as one big family, each member with an important role, working together in mutual respect and support — always striving for the best for one another.
We warmly invite you to visit us and see firsthand what we can offer your children during the most formative years of their lives.
A child's happiness
is key to success.
Throughout the year, we organize various activities designed to build confidence and self-esteem. Primary students also participate in school assemblies, where they proudly perform in front of their peers and parents.
For every child to graduate with a strong academic foundation, fully developed potential, emotional intelligence, excellent communication skills, and the confidence to think critically and solve problems independently.
A school where academic rigour and genuine warmth are not in tension — where children are stretched precisely because they feel safe, and where a Cambodian education and an international one are the same thing.
Your child will be known — by name, by strength, by the thing they are quietly struggling with. You will hear from us before you have to ask, and you will always be able to walk through the door.
Respect. Responsibility.
Kindness. Justice.
Giving your best.
Our school culture is grounded in five core values, instilled in students from the moment they walk through our doors — one for every petal of the Bloom mark.
Respect
For each other, for our teachers, and for the country we learn in.
Responsibility
Owning your work, your words, and your part in the class.
Kindness
How we speak to a struggling child is the whole curriculum, taught silently.
Justice
Doing what is right based on your own values and integrity in the world around you.
Giving the best of oneself
Not perfection — your best effort, every day, in front of people who notice.
