According to the National Home Education Research Institute (NHERI), the average homeschool GPA is 3.3. However, this number is based on a small sample size and may not be representative of all homeschoolers.
Another study by the University of Maryland found that the average homeschool GPA was 3.1. This study was based on a larger sample size, but it still may not be representative of all homeschoolers.
Ultimately, the best way to determine the average GPA of a homeschooler is to look at the individual student's transcripts.
