To get information about The Phoenix Program Naples directly from staff and faculty members, I recommend calling the school at (239) 377-1100.
Judging from this description of the school on the Collier County District website, it looks like Phoenix Naples is offered as an alternative venue for students who either have been, or are about to be expelled from their usual school. Collier County offers several such alternative programs, but they seem to be mostly geared towards students with behavioral issues.
Here's a list of alternative schools near Naples, FL. For the most part, the alternative schools in the area are private; however, you should still contact them or visit their websites to see what kind of financial aid they offer.
