They can then enroll in a traditional 4 year school as a junior if they choose to pursue a Bachelor's degree or go into the work force, depending on their goals.
I would have loved this when I was in high school. I was 1 credit short in my junior year of what I needed to graduate right then. My senior year was essentially a waste except for getting that 1 credit. The school system I was in only had college-credit classes available at 1 school (not mine) and I didn't have a car so there wasn't much choice.
The trouble with this is that we have kids graduating from HS who do not have enough accumulated knowledge to qualify as college freshmen. Look at the percentage that actually finish biology, physics and chemistry..look at the percentage that get as far as calculus in math. Very few.
Look at how many have actually done research papers and original writing. What passes for a HS education in the US is nothing compared to Europe or Asia. They have had more hours and more learning.
