Students with various personality exist in the classroom community such as junior high schools, and there it is demanded that teachers perform appropriate class administration. Therefore, the study on classroom forming the model using the multi agent system is conducted frequently. One of such studies includes the one which pays its attention to the communication between agents. In this paper, we focus on the study and suggest the simulation that is almost a more real communication method. Concretely, we propose extended model using ‘Assertiveness’ and ‘Empathy’ as communication skills between two people. Experimental results showed that these skills are effective to obtain positive likabilities.
