on common app: does a Dual Enrollment class count as class at another college?

kiddo took a class in the physical high school, taught as a DE class, paid for credits at local state u; and has college credit now from that state u. Does this need count as “course work at another college/university?” on the common app? I think I know the answer; want to make sure. THX!

Yes

It’s a minor point, in your case. You can list the other college without worrying about consequences and the grade appears on the transcript, right? You can put one line in Addl Info that the college course was DE at the high school. No harm, no foul.
