Many of you are implying that the school must inform parents of going ons at school, that they're obligated, but yet it's still ok that parents haven't bothered to meet the teacher
I strongly suspect that a school has written guidelines or a charter about when they will contact parents. Do schools have a similar charter for parents saying they need to arrange to meet the teacher? Or info will only be provided to those who do?

The Victorian education website, does not anywhere suggest that you need to be checking in with teacher or meeting unless you have a specific issue to address.
