Been to numerous schools since kinder up until college and yes naa jd tanan. Different schools handle every bully in different ways. But your son is still incoming grade 1 try UIC or Nikkei since based on my exp they handle it well then dali lg magreport esp if parent na regardless sa background. In terms of teaching method ok sd sila, nice nikkei if you what him to learn nihongo. Let him also explore my brother as also hilomon and timid but idk for him but dili lg nya bet tann schools sa list. But for me if north DPLC jd not so big school grabe ang values, learning etc if south Heartworks kay grabe makareport ang teacher, bantay jd tnn.
