The Learning Transfer System Inventory (LTSI) was developed to identify a select set of factors with the potential to substantially enhance or inhibit transfer of learning to the work environment. It has undergone a variety of validation studies, including construct, criterion, and crosscultural studies. However, the convergent and divergent validity of the instrument has not been studied. Such a study is necessary to define the nomological network on the constructs. This study examines the convergent and divergent validity of the LTSI with twenty-eight comparison measures. Results indicate mostly divergent relationships, further demonstrating the uniqueness of the LTSI constructs. By establishing the divergent relationship with other known constructs, the LTSI's usefulness for transfer research is enhanced. (Contains 4 tables.)
