Our public schools never had church alongside, only the private Catholic church schools here, we dodged the bullet..., although assembly all had to recite the prayer.
The junior schools practiced this and some still do. I was not Catholic and my old school was next to a church. The school has since been demolished, the church remains. We have thousands of them here.
Our schools still remain and in use, our original church was demolished years ago for freeway to be built and moved, all still in relatively good condition to my knowledge.
Living in a country with many languages in play, most still remain segregated in the language aspect, as it was so it still is.
