For a post that supposedly was just to tell us how things worked for your kid, you sure are critical of the choices others have made. And to what appears to be your surprise, your kid apparently thrived, both in “jail school” and what I assume you would consider “jail college”, since she is at a state flagship. Maybe… just maybe… “jail school” can work well.
Also, although you may think that term is “cute” because you use it in your family, it is pretty clearly meant as a slur. Like other types of slurs, just because it is used in your home doesn’t make it right to trot out in public.
