From the paper:
Acceleration Composite = 1 × AP Courses +
1 × College Courses +
4 × Grades Skipped
"The average age of high school graduation was for Cohort 1: M =
17.8 years (SD = 0.62); for Cohort 2: M = 17.7 years (SD = 0.76);
and for Cohort 3: M = 17.2 years (SD = 1.02)"
According to figure 2 (pg 5), only 52 of 1497 (= 3.5%) students graduated from high school at an age ≤ 16. So it seems like this study is measuring very modest levels of acceleration, most of which probably comes from AP courses. I don't think this study tells us much about 20 year-olds with PhDs, or what would happen if we put an 8-year-old in a high school literature class, or if we separated everyone into different tracks an a young age, or a lot of the other things people are discussing in this thread.
