Is there a more gender-neutral and specific term for "Underclassman"? Yale has changed their language, but I don't see a clear alternative here.
At this point, I think referring to students by their specific class years ( &quot;First-Years and Sophomores&quot; vs. &quot;Juniors and Seniors&quot;) is the best alternative for now, particularly because of the ambiguity around what class years the terms &quot;underclassman&quot; and &quot;upperclassman&quot; really refer to.
Referring to years verbosely makes sense to me.

First-years and sophomores


First and second years

Or if you want a different meaning

First through third years
