When 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.
