ESF is English Schools Foundation. If you're going to be in HK to primary level at the least, you prob. need to consider what you will be able to afford. E.g. the big international schools are out for us cost wise, but local isn't an option as my husband and I don't speak Cantonese. ESF is our best option (slightly cheaper monthly fees, no debenture, British curriculum). There are ESF kindys, or you can go to one of the other private english speaking organisations. You'll find there are those that are more focused around 'creative play', those that are more slanted toward formal eductional and some in between. Transport is a criteria for us too, I don't want my bub commuting for any length of time or travelling on a 'school bus' alone. With some kindy's you can do 'pre-kindy' classes that you attend with your child, or do just a few half days a week.
