Which schools do you recommend in the Katong belt? Tao Nan Ngee Ann Tanjong katong primary school CHIJ Katong primary Opera Estate

The unrivalled best is Tao Nan. It's the top 5 school in Singapore. Frankly all the schools in this area and in your list are pretty good. I am from CHIJ Katong Primary. It's not too bad. In 2014, about 13% of the school scored above 250. The national average is 8.6%. 74.9% of the school was eligible for express vs national average of 57.4%. The kids fro CHIJ Katong are strong in English but weaker in Chinese. I believe they score lower than the national average for Chinese.
