The aim of this paper is to clarify the conditions of forming OJT (On-the-Job Training) using sociometric data, focusing on direct learning and modeling. The four characteristics related to identification and zone of indifference was regarded as condition variables. The results indicated that forming OJT required (a) trainer’s higher (level of) identification and lower indifference, (b) trainee’s higher identification and higher indifference, (c) trainer’s and trainee’s higher identification in relationships, (d) trainer’s lower indifference and trainee’s higher indifference in relationships. Also, additional analysis revealed that modeling needed the “adequate range of difference” in regard to identification.
