The Actiotope Model of Giftedness (AMG) focuses on person--environment interactions to define giftedness. The development of the Questionnaire of Educational and Learning Capital (QELC) was based on the AMG. The first aim of this study was to present the reliability and validity of a Turkish version of the QELC for 10th grade students. The second aim of this study was the administration of the QELC in gifted and non-gifted students and the determination of mean QELC-scale differences between both groups. Two different samples were included in the study. In the first sample, 421 10th grade students took the QELC (147 boys, 274 girls). The second sample consisted of 38 gifted students and 38 non-gifted students, the latter randomly selected from the first sample. In addition to the QELC, confidence in one's competence, failure coping, stability and modifiability beliefs regarding one's action repertoire were assessed and used to validate the QELC. School grades were collected, too. Results of a confirmatory factor analysis supported the two-factor structure of the QELC (i.e., educational capital and learning capital). The results supported the validity and reliability of the Turkish version of QELC. Gifted students had lower scores in educational as well as learning capital than non-gifted students.
