Dear Lucyhere,
The good news is that there are no bad schools in Singapore.
To summarize: the consensus (it doesn't mean it is the truth of course) is that the 3 best schools in Singapore are the 3 non-for-profit schools:
- Singapore American School (SAS) following a US curriculum.
- UWCSEA following an IB curriculum.
- Tanglin trust School (TTS) following a UK curriculum till year 11 then 2 paths: A-levels or IB.
Dulwich College Singapore might be a great school but it is a new school so it does not have any exams results yet. And it is a for-profit school. Like all the other schools I haven't mentioned.
Comparing exam results: apples to apples:
TTS has the best results.
TTS has better iGSCE and IB results than UWCSEA (both campus).
Fyi I believe comparing iGCSE results is more meaningful than comparing IB results because all students take this exams and it excludes the 'scholars' UWCSEA might bring (or not) to push up IB levels.Anyway fwiw TTS has the best results at iGSCE and IB.
Dulwich Singapore does not have any results yet.
UWCSEA and Dulwich are slightly more international than TTS but TTS is still very international: many of the British kids passport holders are from mixed families or are kids who grew up abroad.
But it is true that TTS students native language is overwhelmingly English. Which is not the case at UWCSEA and Dulwich . I feel the level in English is higher at TTS vs other schools as a results. (And the level in foreign languages less good).
Regarding extra curriculum activities (sports, musics, drama,...): all the schools are fantastic. UWCSEA campus might be a bit more impressive than TTS (though TTS is getting better and better) but we do prefer TTS location: closer to city center and located in One North (Singapore own silicon valley/bio technologies cluster).
Regarding waiting lists: in Senior schools, waiting lists are not very long anymore due to new schools opening (including Dulwich) and a temporary slowdown in oil/gas industries (many expats left singapore last couple of years). So do check before assuming it will be hard to get into TTS. Demand is high but if you are willing to wait 1 quarter (and send your kids somewhere else in between) they will get in.
Both UWCSEA and TTS are fantastic schools. Dulwich might end up being great as well and our friends with kids going there are very happy. But as a TTS parents, I cannot tell you strongly enough how happy we are about TTS.
I hope it helps.
