In brief
Originally launched as Razum International School in 2019 before rebranding to Astor, the school occupies a small Tanglin Road campus with Principal Shannon de Winnaar leading since 2020. The school follows an interesting hybrid approach, combining the International Primary Curriculum for thematic learning in subjects like science, history and geography with Singapore's Ministry of Education syllabus for mathematics and English. This blend provides international breadth while ensuring academic rigor in core subjects.
What sets Astor apart is its flexible structure - core subjects run for just four hours each morning until 1pm, after which families can choose from optional enrichment activities or pursue external programs. With maximum class sizes of 20 students and a total capacity of 150, the school maintains an intimate, family-like environment. The student body is primarily Japanese, reflecting Singapore's expatriate demographics, though the school welcomes holders of Dependent Pass, LTVP, or PR status. Recent recognition includes gold for Principal of the Year and silver for Best Affordable International School at the 2024 Singapore Education Awards.
Strengths
- Exceptionally affordable fees at SGD 16,900 annually - among the lowest for international schools in Singapore

- Flexible schedule with core subjects ending at 1pm, allowing customized afternoons
- Hybrid curriculum combining international breadth with Singapore's rigorous maths and English standards

- Limited on-campus facilities compared to larger international schools - partners externally for swimming and sports
- Very small scale may not suit families seeking extensive extracurricular programs
- Relatively new institution (founded 2019) with limited track record compared to established schools
- Afternoon enrichment activities incur additional costs beyond the base fee
