I really went down a rabbit hole for this. The closest I found was an Allnurses link suggesting that there might be a 6 month RN school in Florida. No one could confirm but they threw out Sienna College and Med-life Institute as possibly being the place. If it is Med-life institute, there's an enlightening longish thread about them here on Allnurses going from 2017 to just a few weeks ago.
I looked them on up FL BON pass rates though the most recent I found was 2017. From their 5 campuses, they had 55 students take the NCLEX and 9 pass (that's 16.33% pass rate). Needless to say, that may have been contributing to their problems which have become acute.
It seems I was wrong (not afraid to admit when I find it's true), some programs are very fast because they have testing-out options, some people mentioned 6-7 months though I couldn't find out if this was initial licensure ADN or LPN to ADN. Either way, that's fast. They do seem to be in that status of State-approved, but not accredited, so you might have trouble if you want to go to another State or if you wanted to pursue a higher degree though some on the thread said they had been able to do both.
Their website isn't working and the end of the thread had people posting what they had been told when they called (that the school was not enrolling new students), and finally a letter from the administrator saying the initial licensure ADN program was no more. Some of the posts seemed to confirm your friend's experience, that students attend a weekend clinical once a month, so I bet these are the same people.
Overall, best of luck to your friend. I hope she/he finishes before the school closes down for good. You can't stay in business with NCLEX pass rates that low but even then it doesn't mean people can't learn enough to pass the boards (16+% have after all).
