We're very glad to have sent our kids to GUG kindergarten. They're not just strong in teaching the academics but also increase self-confidence and general knowledge. Without a doubt I'd say they prepare students very well for Primary schooling and life skills. Personally we had no issues with male cleaners but thought they were professional and standards of hygiene kept very high. In addition to English and Science which are the school's forte, since 2 years ago there's been a lot emphasis on Maths and we're v happy with the Mandarin curriculum too. All in all, excellent kindergarten! I also think a testament to how good a school is when their classes are almost always full. My nephews tried to enroll in their N2 and K1 classes for next yr but unfortunately long waitlist! There is more \"live\" info and feedbacks in their newsletter @ http://www.gug.com.sg/newsletter which I think may be useful or interesting if you're considering this school for your child.
