In my high school they were passing people who were functionally illiterate to keep funding up. It was pretty much assumed those kids were a lost cause so they never got any extra help either. School would just look the other way as someone was lost in the cracks and passed on paper. The very rare ones that did manage to get extra help would take tests in a different room and it was well known the aids would just give them answers if they took too long. Everyone hated it especially the kids being passed through. They got ostracized for "having it easy" while also being frustrated they're spending all day being told to focus on stuff they don't understand and aren't getting real help with
