Some things I found really interesting. Even, if you choose to homeschool you still belong to your local school district and need to pay tuition fees to the school. The good part being, if you decide that you still want your child to attend some classes at the school then they have the right.
Our plan is to send them to school for grade 1 and 2 then homeschool from then on. This, we hope, would give them a good foundation in Chinese. Afterwards we would send them to school for Chinese class and maybe some extra curricular activities.
Looks like a nice support group of local, mixed and foreign families. They have google groups you can join and several websites including www.homeschool.tw
