We analyze the psychometric properties of the German version of the ‘Adaptive Leadership Competency Profile’ (ALCP) (Sherron, 2000), which contains eleven scales assessing broad leadership competencies. We illustrate an approach to the probabilistic test-theoretical analysis of competency models according to the Rasch model. Based on the ordinal Rasch model, item and scale analyses demonstrated Rasch homogeneity (N = 311). A mixed Rasch model was used to inspect whether the different types of staff can be scaled jointly. An 11-dimensional Rasch model was used to explore the latent correlations among the person parameters. All scale means discriminated between executive managers and staff members. We discuss strengths of the approach and practical implications.
