Education Heritability

Education attainment is typically defined as the highest grade someone achieved before leaving the education system. It is 40% heritable and 36% common environment Branigan.. When you recall the biases in twin studies, it seems likely a perfect measure of quality would bump both estimates (but especially the heritability one) up further.

Conversely, while a UK study similarly found 48% genetic and 18% common environment for whether someone enrolled in university, university quality was 62% genetic and only 3% common environment (see Table S3 in the supplement of Smith-Woolley), which is unsurprising, since the same study found that entrance exam scores are 62% genetic and 7% common environment.
