alt Hacker NewsWhen I was a kid, a grade below 75% average on all your subjects will make you repeat the level. I think that is not allowed now (repeating a level). My kids are now 5 & 9. They are on an IB program school. They show us a chart of where your kids lands statistically compared to other kids. I don't know where the statistics is derived from. I don't get a straight answer if every time I ask where the progress graph is taken from.
I can't speak for your region but not failing younger kids isn't political here. It's a response to the developed understanding that doing so has worse outcomes, not better. At younger ages there is a much broader range on skill development. My oldest was reading chapter books in Grade 1 and my youngest is still struggling with basic sentences in Grade 3. The solution is that he's allocated some 1:1 time with a teacher who focuses on the weaker spots.
Holding kids back a grade is really just a sloppy solution. It kind of speaks to, "we have nothing to offer. The best we can do is just teach you the same stuff again." It's essentially a sign of bad, or underfunded education.
