<p>Some universities handle dual enrollment admissions separately from regular undergraduate admissions, with a simpler form that is more appropriate to younger students. In these cases, admission to dual enrollment does not guarantee admission as a regular student, although it would be probable. If the university your son would be attending has an arrangement like this, then he could probably handle things himself, although you might want to contact admissions to find out how they handle admission to dual enrollment. (Most people would not consider that to be inappropriate intervention on behalf of a 13-year-old.)</p>
