ADE standardized variance components (corrected for sex and SES), including the variance attributable to rater (95% CIs in parentheses).

	A	D	E	Rater (Teacher)
School Performance	0.712 (0.609–0.757)	0.022 (0.003–0.105)	0.192 (0.183–0.221)	0.073 (0.044 –0.011)
Self–control	0.410 (0.261–0.538)	0.276 (0.207–0.374)	0.311 (0.286–0.315)	0.002 (0.000–0.113)
Grit	0.139 (0.093–0.226)	0.437 (0.371–0.512)	0.209 (0.194–0.231)	0.212 (0.183–0.250)

The four variance components are standardized, so add up to 1.

The standardized A component gives narrow-sense heritability and the standardized A component + the standardized D component gives the broad-sense heritability.
