It's just PR spin. First year enrollment set a record from 590 last year to 774 this fall. Overall enrollment is probably flat or up by a handful. That would actually make them one of the best in Minnesota. MSUM has been declining for decades. In the 90s they had over 9,000 students. Today it is roughly 4,200.
If NDSU grows total enrollment by 1% I would be ecstatic.
