This study proposes and verifies the concept of the technology disposition, comprised of predisposition and competence. It examines the reliability and validity of a measure of the technology disposition of teacher education students, the Technology Disposition Scale for Teacher Education Students (TDS-T). The TDS-T is comprised of two subscales: technology predisposition and technology competence. In this study, the TDS-T was completed by 656 teacher education students. Results showed the proposed disposition model of predisposition and competence had significant relationships with gender and class year. Male students had significantly higher overall technology disposition scores than did female students, but these differences were due to the male students’ strong self-concept, especially self-confidence. Students’ technology competence level was significantly higher for seniors than for sophomores. The overall technology disposition scores significantly increased from junior to senior years. The TDS-T demonstrated content validity through factor analysis and convergent and discriminate validity through item analysis. The value for Cronbach’s alpha was .93, indicating highly satisfactory reliability.
