NISC is the only three-programme IB World School in Cambodia, running PYP, MYP and DP from age 2 to 18. Operated by Nord Anglia Education on an 8-hectare campus in Sen Sok, founded 1997. Around 800 students.

DP results sit consistently above the world average, with strong bilingual diploma rates among recent cohorts. Fees run roughly USD 14,000 to USD 32,000 a year. Accreditations include CIS. Facilities include an aquatics centre, covered basketball and tennis courts, a dedicated early-learning area and performing-arts spaces. Head of school Frances Morton.

Families value the experienced and attentive teaching, the green campus and the strong sports offer. Parents describe a settled community where children look forward to school, with soccer, basketball and the pool coming up repeatedly. The grumble that surfaces is a wish for richer music and arts extracurriculars at primary. Best fit for internationally mobile families in Phnom Penh who want a full IB pathway, Nord Anglia continuity for transfers, and a campus that competes with the regional names.

  • Northbridge sits in the top tier of Phnom Penh schools alongside ISPP, AISPP and CIS in Reddit and r/cambodia threads, with tuition between USD 15,000 and 30,000.
  • Parents praise the green campus, grass fields, sports facilities and the family atmosphere; community spirit is a recurring theme.
  • Academic delivery is rated strongly: a 100% IB Diploma pass rate and the top IB outcomes in Cambodia are repeatedly cited.
  • Teachers are described as caring, qualified and experienced, with international hires drawn from other Nord Anglia schools.
  • The pool is overwhelmingly positive; no consistent negative theme surfaces, although the Nord Anglia operator and the price point are noted by Phnom Penh parents weighing CIA or AISPP at lower fees.

Positives

  • Tier and reputation. Grouped with ISPP, AISPP and CIS as the top four schools in Phnom Penh.
  • Campus and facilities. Grass fields, green campus and sports facilities cited as a draw.

Considerations
