I have y kids at SRIS and I am very happy there. And so are they.
Academically speaking, it ranks amongst the top British schools. And I am not just talking as a happy mother. they post the SATS results (tests taken at the age of 7, 11 and 14 by ALL kids in the UK-government organised AND corrected) on their website and the kids’ scores are much higher than the average UK scores! In spite of the fact that over 30% of all children are non native speakers!
Most British schools in Shanghai do not even take part in the official SATS testing as they are afraid of the outcome.
