I would talk to the instructor about the level of the prerequisite course and try to determine where your dd is truly at relative to what's expected as a prerequisite for going into the course she's interested in. I agree with everything Val said above, especially with the note that a score on the ACT is a very different measure than actual written composition.
I wouldn't automatically assume she doesn't have the prerequisite knowledge (I've seen examples in some coursework at our local university that's truly basic catch-up at a very low level), but I would definitely talk to the instructor or another instructor within the department to be sure she does have the prerequisite knowledge before assuming she does. If she doesn't (and even if it's a close call), I'd recommend she sign up for the first level course, and explain to her that it's required before moving into the other course. If she really wants to take the other course, it's a small life lesson in putting in the work required before accomplishing something that's worth accomplishing.
Best wishes,

eta - another person to talk to might be the coordinator of the program your dd would be enrolling under - our uni has a specific person that high school students go through when applying and registering for courses, and that person has been very helpful to us in understanding what courses etc as well as what other issues to consider for our ds.
