Jordanian policymakers rely on trained supervisors to lead organizational change in public administration. The impact of training, however, remains weak unless trainees apply what they have learned (training transfer). In order to assess training transfer, the present study validates a Classic Arabic version of the Learning Transfer System Inventory (CALTSI). The instrument was administered to a random sample of 500 supervisors. Exploratory factor analysis with oblique factor rotation validates 15 of the original 16 factors of the LTSI and explains about 65% of the common variance. These findings and their implications are discussed. (Contains 4 tables and 1 figure.)
