About 28 percent of the NELS 1992 12th-graders were first-generation students (figure 1). However, they represented 22 percent of those who entered postsecondary education between 1992 and 2000, indicating that first-generation students were less likely than other students to attend college within 8 years after high school. Roughly 4 in 10 (43 percent) first-generation students who entered postsecondary education during this period left without a degree by 2000, while 24 percent had graduated with a bachelor's degree (figure 1). The opposite pattern was observed for students whose parents were college graduates: a large majority (68 percent) had completed a bachelor's degree, while 20 percent left without a degree.
As in earlier studies (Ishitani 2003), this report found that first-generation students had some family and background characteristics that are associated with attrition. Compared with their peers whose parents were college graduates, first-generation students were more likely to be Black or Hispanic and to come from low-income families. They were less prepared academically for college as demonstrated by their lower rates of taking higher-level mathematics courses in high school, their lower senior achievement test scores, and their lower college entrance examination scores. They were also more likely to delay postsecondary entry, begin at a 2-year institution, and attend part time and discontinuously. These characteristics, as shown in earlier research, put them at potential risk for not persisting in their postsecondary studies and completing a degree (Nuñez and Cuccaro-Alamin 1998).

Previous research has found that students from disadvantaged backgrounds do not earn as many college credits as their more advantaged peers (McCormick 1999). They trail their peers in credit accumulation as early as the first year of their enrollment. Because first-generation students are more likely to come from low-income families and have similar risk characteristics, they exhibited the same patterns. As shown in figure 2, first-generation students trailed their peers in the number of credits earned beginning in their first year of college: on average, they earned about 18 credits in the first year, compared with 25 credits earned by students whose parents had a bachelor's degree or higher. One-in-three first-generation students (33 percent) earned 10 or fewer credits in the first year, compared with 12 percent of those whose parents had at least a bachelor's degree. Like earlier studies demonstrating the relationship between credits earned and postsecondary outcomes (Adelman 1999; McCormick 1999), the current analysis shows that the fewer credits earned in the first year was associated with a reduced likelihood of attaining a degree and an increased time to degree for those who earned one (table 1).

First-generation students continued to trail their peers in overall credit accumulation as they progressed through postsecondary education: they earned an average of 66 credits during their entire period of enrollment through 2000, compared with an average of 112 credits earned by students whose parents were college graduates (figure 2). Part of this difference reflects the fact that first-generation students were more likely than students whose parents had graduated from college to start college late, disrupt their enrollment, attend part time, and leave without a degree within the time period of the study. The gaps in credits, both overall and in the first year, were also found among those with bachelor's degree goals who attended 4-year institutions (figure 2).
