“From 1993 through 2008, Biden was an instructor at the Stanton/Wilmington campus of Delaware Technical & Community College,^[12][18][19] where she taught English composition and remedial writing, with an emphasis on instilling confidence in students.^[18][20] She has said of teaching at a community college, “I feel like I can make a greater difference in their lives. I just love that population. It just feels really comfortable to me. I love the women who are coming back to school and getting their degrees, because they’re so focused.”^[18]

Biden later returned to school for her doctoral degree, studying under her birth name, Jill Jacobs.^[16] In January 2007, at age 55, she received a Doctor of Education in educational leadership from the University of Delaware.^{[2][23][24][25]} Her dissertation Student Retention at the Community College: Meeting Students’ Needs was published under the name Jill Jacobs-Biden.^[24]”
