Both my dc are in secondary in Ireland and both their schools regularly post on Facebook.
Their primary school was very clued up on digital responsibility. We were asked annually for permission annually to use their image in sm. Photos of activities tended to be from the side/overhead and names were never used. They only posted on their own school blog.
I don’t believe I’ve been asked for consent by either secondary (although I could conceivably have missed something), and they regularly show the kids faces front on with full names. They also occasionally post information on where they will be - trips they’re going on, or which university a school leaver will be attending.
I’m curious whether this is the norm with schools or not and if I’m being unreasonable to raise it as a concern.
