The three kinder that you like is quite different in nature. It really depends your piority of your kid's education. How old is your kid now? Is he/she attending any play groups?
Your choice No.1, I guess you chose is because it is close to where you live. No.2 is a international school and is for future if your kid not in HK education system. No.3 is a famous local kinder but with strong English teaching e.g. each class have NET and Chinese teacher as class teacher.
I suggest you should: 1) think ahead what type of Primany school you want your kid go to 2) what is your kid's character, e.g. is she fit for local type of discipline or more open style international school 3) location of school e.g. kid travel for 1 hours each day per trip between kinder is too much for them...
May be others parent could give you some more ideas. You can also spend some more time click into each school discussion group and observe. :
ALSO, Last but not least, even you had your most wanted school, it is a 2 way relationship-- you still need to apply and pass through their interviews!!! I guess start searching now is good.
