The purpose of this two-phase study was to validate the giftedness checklist of Sommer, Fink, and Neubauer (2008) in the Italian context, in both the version for teachers and for parents. The first phase was conducted with a sample of 570 children, 392 parents, and 136 teachers, with the aim of exploring the instrument factor structure, and analysing its psychometric properties. In the second phase, ratings provided by teachers and parents on the instrument were examined to investigate whether the instrument successfully discriminates between gifted and non-gifted students. Results indicate the usefulness of the instrument in the identification of giftedness.
