Both our kids have attended high scope in Bali for a good few years now.
They are a good school to be honest and I have a pretty good relationship with the boys teachers and the headmistress is a personal friend.
They paint themselves as a very progressive school and in some ways they are but they still struggle to adequately handle issues of bullying and religious education is the usual brainwashing bullshit. I have confronted the school on both issues.
The boys eventually realised that as twins they hold the advantage and the pair of them gave the bully a good hiding. My wife had also confronted the school a number of times on the issue and when the call came she pointed out that she had already pointed out that their limp wristed "problem solving sessions" they do with the kids was a waste of time and if they had grown some balls and dealt with it like responsible adults in charge of a school then it wouldn't have resulted in a smashed laptop and a broken nose.
As for the religion shit I have argued the case that I want my boys to learn a bit about Christianity and Hinduism (we do live in Bali FFS) but they flatly refuse even as an extracurricular lesson because as muslims they can only learn about Islam.
The boys are 13 now and we discuss things on the subject, my kids soak this up and now challenge the RE teacher who doesn't answer their questions and wont engage in any debate - so its the usual brainwashing "accept what I say mentality"
Apart from that generally we are very happy with the school and its curriculum. The homework regime can be a bit heavy. But the lessons are interesting and the kids seem to enjoy school. The snobbery aspect of the parents isn't an issue in Bali and I'm pleased that my kids transcend all the economic spectrums of their school friends without issue or prejudice.
