Abstract

Differentiated Model of Giftedness and Talent (DMGT) explains that every person has innate potentials that can be transformed into talent [1]. The initial construction of Managerial Aptitude Test developed to measure the three dimensions: cognitive, metacognitive, and creativity, using Classical Test Theory (CTT) approach and shows satisfactory result. The current study further examined the psychometric properties of Managerial Aptitude Test using one-parameter Item Response Theory (IRT), Rasch Model. Cognitive dimension was chosen from the three dimensions of Managerial Aptitude Test based on the dynamics of thinking process in decision making among the research sample. Rasch model analysis performed to measure item difficulty level in term of participants ability. Total of 413 employees from three different types of company (Government, State-owned, Private) participate in the study. The result of Rasch analysis supports the unidimensional of 25 items in Cognitive Dimensions. Person-Item map shows same logit value = 0. In term of item difficulty level, 3 items have high difficulty level where none of the participants able to answer the items. On the other hand, 3 items also found to be very easy, therefore every participant (include participant with low potential) able to answer those items correctly. Item validity indicates the need to eliminates item 1, 14, and 15. Differential Item Functioning result shows several items contains bias.
