Invictus International School began as a group in 2015. It operates as a proprietary brand under Sing‑Ed (the education arm of Acrophyte Pte Ltd, formerly Chip Eng Seng Corporation Ltd.), with headquarters in Singapore. The organisation reports rapid growth from an initial intake of about 40 students and 15 staff to a multi‑campus network of several thousand students and hundreds of staff. The Phnom Penh campus opened as part of that regional expansion (the group's expansion into Cambodia is noted in the Invictus timeline).
The Phnom Penh campus describes an active school community made up of students, local and expatriate families, and teaching staff who take part in regular school events. Recent News & Events posts highlight activities such as Spirit Week and Sports Day, seasonal celebrations (for example Christmas), curriculum‑linked trips and outdoor learning days, and inter‑school sports participation. The campus also stages open‑house and charity events that invite parent participation and raise funds for local organisations.
Across the Invictus network, parental engagement is formalised through a Parent‑Teacher body (sometimes described as a Parent Support Group/PTA) and parents are routinely invited to be active members. Invictus Singapore materials note that the PSG/PTA helps plan events, fund prizes, run workshops for parents and provide volunteer support for school activities. At the Phnom Penh campus, recent open‑house and charity carnivals explicitly involved parents and raised funds for a local NGO (Carrying Companions), indicating PTA/parental participation in fundraising and event delivery. In practice these groups typically organise or support fairs, performances, sports days and information workshops, and they offer multiple volunteer roles for parents who want to help with hospitality, stalls, or classroom support. Membership and committee structures are regionally managed (Invictus schools commonly operate a campus‑level parent group or committee that liaises with school leadership).
Invictus International School Phnom Penh is a co‑educational day school for students aged 3–18 that follows the UK Early Years Foundation Stage in Nursery and Reception, the Cambridge Primary and Lower Secondary programmes, IGCSE and Cambridge A‑Levels.
