One more thing, I have no intention of criticizing the school my children attend. However, I miss the life in South Africa where I greeted and hugged the classroom teachers and other parents I met after class.
Please do not misunderstand me as a typical Asian parent who values academic ability. I am an art teacher and my wife is a Montessori teacher. We want to give our children a more comfortable, free and confident education. But even the largest and wealthiest schools in the country have a shortage of art teachers, so they teach seasonally (e.g. art in the spring, music in the fall).
Separately, I have visited numerous countries such as Thailand, South Africa, Cambodia, and Japan, but I have never seen a country with a high percentage of 'locals' despite the name of an 'international school' as much as Mauritius. In the case of our eldest child, 3 foreigners out of 22, and in the case of the youngest child, 4 foreigners out of 25. The rest are all locals.
