Behavioural genetics regards intelligence and educational attainment as highly heritable (genetically influenced) and polygenic (influenced by many genes) traits. Researchers in the field have moved beyond identifying whether and how much genes influence a given outcome to trying to pinpoint the genetic markers that help predict them. In more recent years, behavioural genetics research has attempted to cross-over into the field of education, looking to play a role in education research and the construction of education policy. In response to these developments, this paper explores PreK-12 American educators’ perceptions of intelligence in relation to genetics and their views on the relevance of behavioural genetics findings for education. It does so within the context of an ugly history tied to race and racism and an uncertain future. Findings from this mixed-methods study suggest that US teachers believe that genetics play an important role in a student’s intelligence and academic achievement. Furthermore, teachers are open to learning more about the inclusion of genetics research in education policy. At the same time, however, teachers believe that the environment, and in particular parents and a child’s home environment, plays a substantial role in a student’s abilities and education outcomes.
