ICS International School

ICS International School has two central Phnom Penh campuses. The Main Campus is at No. 14, Street 214, Sangkat Boeung Raing, Khan Daun Penh, and the Calmette Campus is at No. 25A, Street 75, Sangkat Sras Chak, Khan Daun Penh. Both campuses are located in the Daun Penh district in the heart of the city, offering convenient access for families relocating to Phnom Penh.

ICSIS serves students from Nursery through Year 12. The Primary years follow Cambridge Primary, and the Secondary/High School (Grades 7–12) combine Cambridge Lower Secondary (Checkpoint), Cambridge Upper Secondary (IGCSE), and Cambridge Advanced (AS & A Levels) with a bilingual Cambodian MOEYS component. The school provides a bilingual pathway that integrates Cambridge qualifications with local requirements.

ICSIS is a private international school in Phnom Penh that delivers Cambridge International Curricula alongside the Cambodian MOEYS national curriculum through a bilingual approach. It operates as a Cambridge International Centre and supports international qualifications for a diverse student body.

ICSIS uses placement assessments in English and Mathematics (with Khmer assessments for primary and secondary) to determine initial placement. A formal SEN policy is not published on public pages. External sources note the existence of a Special Needs Preschool option with a sensory room at ICSIS.

The school is located in Cambodia and holds Cambridge International Centre status (KH008), enabling Cambridge examinations in Cambodia alongside MOEYS national requirements.

No religious affiliation is stated on the school's public pages.

The typical school day runs 7:30 a.m. to 4:30 p.m. on weekdays, with Saturday classes from 8:00 a.m. to 12:00 p.m. These hours are listed for both campuses.

A school bus service is not listed on ICSIS's admissions or contact pages; families typically arrange transportation themselves or via private providers.

ICSIS offers a broad, bilingual curriculum for Grades 7–12 that combines the Cambridge International Curriculum with the Cambodian National Curriculum (MoEYS). The Cambridge pathway includes Cambridge Lower Secondary (Checkpoint), Cambridge Upper Secondary (IGCSE), and Cambridge Advanced (AS & A Levels). Nursery and Kindergarten follow the Singapore Curriculum and the Cambridge English Teaching Framework (CAIE), with subjects including ESL, Mathematics, Phonics and Reading, Writing, Science, Arts and Fine Motor Skills. Primary education is taught in English with Khmer studies and follows Singapore and CAIE-aligned programmes; core subjects include General English Programme (GEP), ESL, Mathematics, Science, ICT, Social Studies, Khmer Language, and Arts & Crafts. ICSIS is a Cambridge International Centre KH008 and aligns with MOEYS requirements, offering CAIE examinations, preparation classes, annual progression reports, and field trips.

ICS International School supports Social and Emotional Learning (SEL) through its Co-Curricular Activities (CCA), designed to promote personal growth, creativity, leadership, and teamwork. The CCA offers activities across sports, arts, music, technology, debate, and service projects, and encourages all students to participate, contribute, and grow. The CCA program aims to shape students into balanced, self-motivated, and socially responsible individuals prepared for future challenges. Well-being is a central consideration in the school's ethos, with emphasis on nurturing the well-being, growth and development of each student individually. The school's vision emphasizes the development of socially adept and emotionally healthy people.

Remedial classes are available for students from K1 to Year 12 with a maximum of five students per class. The school also operates a Student Support Service (SSS) that provides tutoring in reading, writing and English-language study skills, with sessions starting at 3:10 pm for one hour on weekdays. SSS is delivered by ICS teachers and teaching assistants and is available to full-day Primary students (Year 1–6) with class sizes capped at ten. A school counsellor may handle certain behavioral issues as part of safeguarding and student welfare. Remedial and SSS provisions are described to support students who are falling behind or need additional academic assistance.

In the early years, English as an Additional Language is integrated into the curriculum, with ESL listed as a main subject in Kindergarten. All Kindergarten and Primary classes are taught in English with Khmer studies as an exception, and English language support is reflected in the curriculum (GEP and ESL). The Nursery & Kindergarten curriculum explicitly includes English as a Second Language (ESL) as a core subject. The program is aligned with Singapore and Cambridge frameworks to support bilingual or multilingual learners. ESL provision is an established part of the school's language offerings in the early years.

Wellbeing is a core consideration at ICSIS, with core beliefs explicitly stating the aim of nurturing the well-being, growth and development of each student individually. The Vision highlights emotionally and physically healthy people as a desired outcome for students. Co-Curricular Activities are described as promoting personal growth and social responsibility, which supports students' social and emotional development. The overall emphasis on well-being is reflected throughout school policy and practice to support students' holistic development.

A formal safeguarding framework exists within the School Policies, including a dedicated policy document accessible through the School Policies section. The Code of Conduct notes that a School counsellor may handle misbehavior, reflecting safeguarding and welfare processes. Attendance and safety measures are in place, such as biometric fingerprint scanning for arrival and dismissal, as part of safeguarding and campus security. The school's approach to safeguarding combines policy, welfare support (including the School Counsellor), and preventive measures to protect students.

1. Enquiry. Start by contacting ICS International School to gain information about the school, programs, and admissions options. The admissions team provides responses to questions about the school and can help you plan the next steps. The minimum age requirements for each grade apply and must be met by 1 September of the academic year (Nursery 2.5 years; Kindergarten 3.5–5 years; Primary 6–11 years; Secondary 12–17 years).

2. Campus Visit. Arrange and attend a campus visit to explore the facilities and meet the admissions team. The visit gives you a chance to observe classrooms, learn about the environment, and ask about how the school supports student needs. You should use this time to discuss any specific programs or support services your child may require.

3. Placement Test. Your child will undertake assessments in English and Mathematics, with a Khmer assessment for primary and secondary students, to help determine the appropriate placement. The results, along with age and background, inform the initial placement decisions. This step ensures that the curriculum level aligns with your child's current abilities.

4. Assessment & Interview. A meeting with your child and with you, the parents, is conducted to understand your child's needs, goals, and learning context. This discussion complements the test results to guide placement and support planning. The interview helps the school gauge fit and discuss any accommodations or program options.

5. Application Form. Complete and submit the formal application form, along with the documents outlined in the Admission Checklist. The checklist includes items such as recent photographs, birth certificate, school reports, and transfer letters where applicable. Ensure all requested documents are prepared to avoid delays.

6. Application Review. The admissions team reviews the application and supporting documents carefully before a decision is made. This review considers test results, interview impressions, and alignment with placement goals. You may be contacted for any additional information if needed.

7. Payment of School Fees. Once admission is confirmed, you will pay the school fees according to the published fee structure. The exact figures and structure are provided to families who receive an admission offer. This payment completes the enrollment, securing the place for your child.

8. Learning Resource Collection. Upon enrollment, you will collect the learning resources, including textbooks and materials. The Admission Checklist specifies items such as 3 recent photographs of the student, birth certificate copy, school reports, and parent photos for collection cards. Collecting these resources completes the onboarding for the new student.

ICSIS operates a Study Abroad & Scholarship Centre (SASC), which offers scholarship programmes to support students pursuing higher education opportunities abroad. The SASC page explicitly lists “Scholarship Programmes” as part of its service portfolio, indicating formal scholarship offerings exist through the centre. Specific eligibility criteria, application procedures, and scholarship amounts are not published on the site; interested families should contact the SASC for details. In addition, promotional opportunities have appeared in press (e.g., early enrollment promotions) that have, in some years, offered discounts on enrollment and tuition for early applicants.

ICSIS does not publish a formal waitlist or pool system. The admissions policy states that admissions are open year-round, and applications are reviewed continuously, indicating that space availability governs placement rather than a defined waitlist. There is no published waitlist process on the site.
