I have absolutely noooo idea.
But before entering a program like this, why don't you look through the classified ads, and find a couple firms that are hiring legal assistants. Call them, and ask them what sort of background they are looking for in someone they would hire.
If they suggest a program such as the one you are looking at, ask which school you should get it from.
I see some ads on tv for stuff like legal assisting and it looks soooo sketchy, however, I'd imagine the local community college might have a good program for the same thing, and even if you can't get into a University, you might be able to get into the local CC. Plus, if you ended up wanting to get a four-year degree, courses would be more likely to transfer?
I would definitely call several different firms to get their input! Let me know how it goes!
