I've been reading about learning loss over the summer holidays (fell into a Google rabbit hole) but most of the information I can find about it is specific to America. Apparently, we also have a summer slide but it is less marked as our holidays are shorter.
And that's about as far as I got. There's not much to say about if this is mostly a problem for younger children or if it's also a problem for teenagers. Is this something that is observable in our secondary schools? If it is, how long does it take teachers to get kids back up to speed again?
