Policymakers have begun to wrangle with the definition of “first generation,” which, according to Maureen Hoyler, president of the Council for Opportunity in Education, entered the legislative lexicon in 1980 as a better way to identify disadvantaged students without referring to race or ethnicity.
I don't think the differing definitions for what makes somebody "first generation" should matter as much as what is required to help students that are struggling. It's unfortunate that people are focusing as much on how much people are disadvantaged instead of what could be done to help each student succeed.
