Asbury and Wai ("Journal of School Choice," 2019) perform a valuable service by summarizing much available behavior--genetic research on academic achievement. However they consider that no specific policies stem from the research body at this time. Here we do propose a policy based on some of our research using twins, namely that…

About 13 percent of children aged 3 through 21 enrolled in public schools received special education services in school year 2015-16, and about 3 percent of children from birth through age 2 received special education services.
