Application and Supporting Documents
After completing our enquiry form and touring our campus, you'll complete our online registration form here on the BIS website and upload the following documents with it:
Entrance Assessment and Interview
We will invite your child to complete English and Math assessments. In some cases, we may also request an interview with our Principal. This process helps ensure that your child is prepared to access our academically rigorous International Baccalaureate programme, and allows us to identify any additional learning needs.
Admission Decision and Fee Payment
Once we have reviewed your child’s application and assessment results, we will send you a formal offer of admission. To confirm your child’s place, you will need to:
Enrolment and Orientation
Once fees are settled, students are officially part of the Bloom International School family. New Family Orientation is held at the end of August, followed by Welcome Coffees during the first weeks of September.
How the decision
is reached.
Three outcomes are possible after we review your child’s application and assessment results together. Both qualifying outcomes then pass through our Admissions Policy before a place is released.
How old is your child?
We serve students from PK3 through Grade 12 (ages 3–18), currently offering classes from Pre-K to Grade 5. Select an age to see the BIS grade and its equivalent in the American, British and French systems.

Thank you for considering a BIS education for your child.
We understand that choosing the right school is a significant decision for families, and we are here to support and guide you throughout the process. School tuition and fees are determined by the student's enrolment status — whether they are new or returning — as well as their grade level.

We serve students from PK3 through Grade 12 (ages 3–18), currently offering classes from Pre-K to Grade 5.
School operates Monday through Friday, from 8:00 to 15:30. ECA students are dismissed 15 minutes earlier at 15:15. Students may arrive as early as 7:30 in the morning. Extra-Curricular Activities run from 15:30 to 17:00 and from 17:00 to 18:30.
The academic year begins in September and ends in June.
Bloom International School is an IB candidate school* for the Primary Years Programme (PYP) — candidacy does not guarantee authorization. The PYP is an inquiry-based, transdisciplinary framework for students aged 3–12, delivered in English. It offers a curriculum designed so that every student can develop their abilities to the highest level.
Core academic subjects are taught in English, with a complementary Khmer program emphasizing language, history and culture. Spanish and/or French and/or Chinese are introduced from Grade 1 to 8, and from Grade 9 to 12 as an elective.
Yes — students start at all times of the year, where we have availability. Older students will require individual consideration due to the rigorousness of the program.
School lunches are offered daily and are included in the school fees.
We welcome students who require additional support due to learning differences, special educational needs or disabilities, provided that — by making reasonable accommodations — our Student Support Team believes they will be able to meet the needs of that student.
In Primary and Secondary School, we provide limited Learning Support services for students with mild learning disabilities and for those who need support in developing early literacy skills and temporary targeted academic interventions. In Pre-University, we offer limited support, such as organizational strategies and extended time on assessments.
A primary consideration in offering admission will be the student's ability to access the regular curriculum with limited support, and the level of resources needed. Unfortunately, we cannot offer places to students who need extensive curriculum modifications or constant one-to-one support.
Prior to applying, parents of children with special needs are requested to submit all relevant documentation to the admissions department — Individualized Education Plans (IEPs), report cards, and doctor or psychologist's evaluations are all helpful.
Yes. BIS students wear the full school uniform when they are on campus during school hours as well as on school outings, as it is a symbol of belonging to our institution. They also wear a sports uniform for Physical Education and sports activities.
A typical day at our international school begins at 8:00 am and ends at 15:30 — except for Early Childhood, who may choose reduced hours. Additional activities may take place during break time, before or after lunch, or after the specified school hours.
You can contact our Admissions Office via the Enquiry Form and they will be happy to guide you through the application process and answer any questions. We advise parents to apply in advance of the desired starting date, as our school has limited available seats per class.
