The graph compares the public school academic achievement curve on the left with the homeschool achievement curve on the right.
The red arrows reflect the difference in achievement between public schooling and homeschooling.
These arrows are all the same length since the homeschool curve is shifted as a whole to the right.
This means that homeschooled students traveling from the 1st percentile to the 4th percentile (measured on the public school curve) receive just as much of an academic achievement boost as those traveling from the 50th to the 73rd.
