Do you mind if I ask what state you're in? My high school made people write down colleges to send their ACT scores to, but I remember the confusion as some neither knew what to write nor were offered guidance afterwards.
As an aside, the push is so strong I ended up leaving high school (after 10th grade) to attend college early at one of our early-entrance-to-college programs that effectively is a building full of high schoolers going to college (and, e.g. being locked in the building at 8pm each night, not being allowed to have a car, etc) and getting backfilled highschool credit for classes also -- you get your high school diploma alongside an associates degree.
It's a massive push, and the assumption is generally a mix of "everyone needs to go to college or you won't find a job" and "you can get a job without college but all those jobs suck and you'll wish you went to college but by then it will be too late". After years of having it hammered into you, kids finally listen. That, and mandatory college applications being part of your class grades (sometimes as early as 8th/9th grade depending on your classes), as well as the school requiring you to send your ACT scores to colleges.
Edit: this was around 10 years ago for me -- my highschool graduation date was 2010 (even though I had been in college for 2 years by then).
