The purpose of the study was to psychometrically characterize the Ethical Leadership Scale (ELS) through confirmatory factor analysis (CFA) and Rasch analysis. Data were collected from 469 teachers across several countries. The one-factor structure of the ELS was confirmed in CFA. ⋯ None of the items showed DIF across gender. Overall CFA and Rasch models provided evidence for the psychometric quality of the 10-item ELS. However, reassessment of the scale after removing Item 4 showed improvement in the psychometric properties of the scale.
