In 2015-16, according to NASPA, 56% of undergraduates nationally were first-generation college students (neither parent had a bachelor’s degree), and 59% of these students were also the first sibling in their family to go to college.
Here's another fact sheet: https://eab.com/insights/daily-briefing/student-affairs/7-fast-facts-about-your-first-generation-students/
Highlight stories of faculty, classified personnel, and administrators who are first generation students:
Their stories could include information like:
Where did you go; what was your first generation experience?
What did you do to help you succeed?
What advice do you have for being a successful online learner?
What college resource do you wish you had taken advantage of?
Your words of encouragement for fellow first generation students
I’m thinking you could collect that through a google sheet/survey-I imagine a lot of people would be interested in participating and you might find you can use that for all kinds of marketing efforts beyond First Generation Day.
