You can have a multi-track high-school system, like in much of Europe. Some are geared towards the academically inclined who expect to go to university, others hold that option open but focus on also learning a trade or specialty (this can be stuff like welding, CNC, or hospitality industry / restaurants etc.), while others focus more heavily on the trade side, with apprenticeship at companies intertwined with the education throughout high school, and switching to a university after that is not possible by default, but not ruled out if you put in some extra time).

Or you can also have stronger or weaker schools where the admission test scores required are different, so stronger students go to different schools. Not sure if that's a thing in the US.
