Common questions from parents

Does “50 percent heritable” mean half my child’s ability is fixed?

No. Heritability is a statistic about differences across a whole population at one time and place, and it tells you nothing about your individual child. The other half of the picture is environment, and the two are tangled together rather than separate. Half heritable is not half fixed.

Is there a gene that decides whether my child does well in school?

No. The largest study found around 4,000 variants, each accounting for at most 0.02 percent of the difference. Even bundled into one score they predict a crowd, not a child, and averaging the parents’ own education predicts a child’s outcome at least as well.

Should I get my child’s DNA tested to find their learning risks?

The geneticist studying this is unconvinced it belongs in education: the scores are inaccurate for individuals, fail outside European-ancestry groups, and reveal no mechanism to act on. A screener of any kind, genetic or otherwise, is a starting point, not a diagnosis. If your child might need formal accommodations such as an IEP or 504 plan, or you suspect a vision, hearing, or medical cause, a professional evaluation is the route to those supports.

If learning is partly genetic, does what I do at home even matter?

Yes, more than the headlines suggest. About a third of the apparent genetic signal for school outcomes is the home a family builds, and the brain keeps rewiring with the right kind of practice. The reading you share, the expectations you hold, and the skills you help build are exactly the levers that move a real child.
