This study aimed to investigate the reliability and validity of the Childhood Career Development Scale (CCDS) on a sample of 1018 Iranian elementary school students. The Confirmatory factor analysis revealed that the original eight-factor model was of a good fit. Measurement invariance analyses indicated equivalence across gender and grade. A factorial MANOVA was applied to assess gender and grade mean differences in CCDS subscales. Concurrent validity of the CCDS subscales with the measures of Locus of Control and the children's Industry was confirmed. The CCDS Persian version proved to have good psychometric indexes for assessing children's career development.
