Being first gen doesn’t automatically mean poor, not encouraged, no frame of reference. In itself, it doesn’t “boost” accomplishments above others. It doesn’t mean they lower the standards and take under qualified kids.
Not all first gens suffer in college. Many have had advantages due to their parents’ accomplishments. Many have siblings who’ve gone to impressive colleges. Many of these kids have their own impressive resumes.
I think the difference to recognize is when kids are low SES, but still busted themselves to get ahead, in the right ways, taken advantage of the many great mentoring programs, and come out on top. They learned self advocacy and seem likely to take advantage of college support.
