Families who home school their children should not feel that the education they are providing is inferior to the traditional K-12 education of their neighborhood peers.
Although not statistically significant, the average first-year GPAs, credits earned in the first year, ACT Composite test scores, and ACT English, Mathematics, Reading, and Science and Reasoning subtests for home school graduates were all higher than traditional high school graduates. Although the sample was relatively small, the ACT Composite test score results for home school graduates was an average of 22.8, which matched identically to the national average in 2000 for home school students (ACT 2000). The national average for all students in 2000 was 21, which was nearly identical to the 21.3 average for the traditional high school graduate.
The academic performance analyses indicate that home school graduates are as ready for college as traditional high school graduates and that they perform as well on national college assessment tests as traditional high school graduates. The results of this study are also consistent with other studies on the academic performance of home school students compared to traditional high school graduates (Galloway 1995, Gray 1998, Jenkins 1998, Mexcur 1993). These results also suggest that a parent-guided K-12 education does not have a negative effect on a student’s college success.
With the anticipated growth in the home school population, state policy makers, home school advocates, and the families who educate their children at home should also benefit from this study on the academic performance of home school graduates.
