New research on college students who were home educated shows they are doing very well.
Dr. Michael Cogan, director of the Office of Institutional Research and Analysis at the University of St. Thomas in Minnesota, compared home-educated students to those from conventional-school backgrounds at one Midwest university.
Controlling for various background demographic, pre-college, and other factors, multiple regression analyses revealed that the home educated earned higher first-year and fourth-year GPAs.
Having been home educated had neither a positive nor a negative impact on these academic outcomes. In simple terms, however, students who were homeschooled did achieve a higher retention rate (88.6 percent) compared to the overall population (87.6 percent).
And the home educated achieved a higher graduation rate (66.7 percent) when compared to the overall population (57.5 percent).
Home educated university students (71.1 percent) were more likely to be male compared to the overall population of undergraduate students (50.3 percent).
Also, homeschooled students were 2 ½ times more likely to receive a Pell Grant compared to the entire group and were less likely to self-identify as a person of color compared to the overall population.
Those at this university who were home educated were more likely to self-identify as Roman Catholic  than the overall population and less likely to live on campus compared to the entire freshman cohort.
Homeschooled students (26.5) reported a significantly higher ACT-Composite score when compared to the overall cohort (25.0), and the home educated (14.7) earned more college credit prior to their freshman year when compared to the overall population (6.0).
Home-educated students (3.37) earned a significantly higher fall semester GPA when compared to the overall cohort (3.08).
Further, homeschooled students (3.41) earned a higher first-year GPA compared to the overall group (3.12).
Finally, the home educated (3.46) earned a significantly higher fourth-year GPA when compared to the freshman cohort (3.16).
Dr. Cogan’s findings that positive things were related to these college students who were homeschooled are consistent with those of others who have studied adults who were home educated.
