Genetic research has a potentially increasing impact on educational practices. This study investigated attitudes towards the utility of genetic and environmental research in personalising education, with comparisons between parents/non-parents and educators/non-educators, as well as how these attitudes may relate to heritability ratings of educationally relevant traits (N = 6,304). Data was collected using the International Genetic Literacy and Attitudes Survey (iGLAS). Overall, participants endorsed environmental research more than genetic research to personalising education. Parents were slightly less likely to endorse genetic (but not environmental) research than non-parents. Educators tended to endorse environmental research over genetic research when compared to non-educators; however, effect sizes were minimal. Participants ranking educational traits as more heritable were more likely to endorse genetic (but not environmental) research in education. Future work should focus on promoting the importance of genetic and environmental research in education.
