The UK Early Years Foundation Stage (EYFS)

The UK Early Years Foundation Stage (EYFS) curriculum fosters learning and development through giving each unique child the opportunities to interact in positive relationships and enabling environments. The first theme of the UK EYFS has educators understand that every child is a unique child, who is constantly learning and can be resilient, capable, confident, and self-assured. Teachers will take time to understand and observe each child’s development and learning, assess progress, and plan for next steps. Next, children learn to be strong and independent through positive relationships. Positive relationships are fostered by teachers who are sensitive and responsive to the child’s needs, feelings, and interests, supporting the child’s own efforts and independence. The last theme in the UK EYFS curriculum is enabling environments. Children learn and develop well in enabling environments, in which their experiences respond to their individual needs and there is a strong partnership between practitioners and parents and carers.

Cambridge Primary Curriculum

The Cambridge Primary Curriculum provides a broad and balanced education for young learners, helping them to thrive throughout their schooling, work and life. The engaging and flexible curriculum ensures that learning is adapted to the child and prepares them for Secondary Cambridge Curriculum. For more information about the Cambridge Primary, please visit: qualifications/cambridge-primary/curriculum.

Singapore Mathematics (Primary)

The Singapore Mathematics model is well-known internationally and has been adapted for use in at least 25 countries, including the USA and Britain. It is a very successful teaching approach which focuses on problem-solving and heuristics. Children are taught the 3-step learning process whereby they move from the concrete to pictorial and abstract. Students engage in hands-on authentic learning experience whereby they actually feel and see the objects. This will then be followed by drawing pictorial representations of mathematical concepts, before proceeding to solving mathematical problems in an abstract way. The focus is on teaching students problem-solving capabilities, as well as practical and critical thinking skills that will help them solve problems in the real world.

Cambridge Secondary Curriculum

The Cambridge Secondary Curriculum is used in over 155 schools in over 50 countries worldwide. Cambridge Secondary Curriculum is jointly developed by the London-based Fieldwork Education and front-line educators from more than 100 international schools around the world, including the UK, the US and Australia. It is an international course in the true sense.

The Cambridge Secondary Curriculum is a concepts-based curriculum design that provides theme-based units featuring learning goals that outline the knowledge, skills and understanding needed across all subjects. The curriculum also provides opportunities for students to enhance their personal dispositions to help them become more internationally minded. The Cambridge Secondary Curriculum promotes learner traits recognised as essential for future success. The full range of units cover adaptability, balance, belief, celebration, challenge, collaboration, communication, community, competition, consequences, courage, creativity, curiosity, development, discovery, entrepreneurship, identity, interpretation, justice, leadership, reflection, relationship, renewal, resilience, resolution, respect, responsibility, risk, structures, and tradition.

International General Certificate of Secondary Education (IGCSE)

The Cambridge IGCSE is the world’s most popular international qualification. IGCSEs is a preparation for the Cambridge International A-Levels, and usually take two years to complete. Assessment ranges from written to oral tests, as well as practical exams and coursework. Students get to choose from a range of different subjects. The exam papers are all marked centrally in the UK, and final results are assessed using internationally recognised A* to G grades.

The Cambridge IGCSEs gives students the freedom to choose a course of study that is right for them. Chosen subjects should fit with student’s career goals or plans for further education.

Cambridge International A-levels (Advanced Level)

The Cambridge International A-Level (Advanced Level) is recognized as a ‘Gold Standard’ qualification. It is a subject-based qualification conferred as part of the General Certificate of Education (GCE), as well as a high school completion qualification offered by established examination boards in the United Kingdom, with more than 55 subject choices available from which to choose. Obtaining an A-Level is generally required for university entrance, with universities granting offers based on grades achieved.

Cambridge International A-Levels generally take two years to complete. Students normally take 3 or4 A-Levels in their first year, and most cut back to 3 in their second year. This is because university offers are normally based on 3 A-Levels. Unlike other Level 3 qualifications such as the International Baccalaureate, A-Levels have no specific subject requirements, so students have the opportunity to combine any subjects they wish to take. However, students normally pick their courses based on the degree they wish to pursue at university. Many degrees require specific A-Levels for entry.

Co-Curricular Activities

At Invictus International School Phnom Penh, learning takes place both in and outside of the classroom. We encourage students to explore, develop and pursue skills and abilities throughout their learning journey at Invictus.

Co-Curricular Activities (CCAs) on offer include Art, Chess, Cooking, Choir, Jiu Jitsu, Football, Swimming, Board-games, and more. CCAs take place between 2:30-4:30pm from Mondays to Fridays.
