Recently, school teachers find new types of hard handling students. They do not always do illegal behavior nor make some troubles. However, they are difficult for teachers to manage them. The purpose of this research is to identify the characteristics of such handling difficulty students comparing with uncontrolled students. Sixty four elementary school teachers and fifty nine middle school teachers were participated in this research. They answered questionnaires with high quality text data about these students. We analyzed them by text data mining with word miner. The results are as follows; the most difficult managing students are related with bullying, school refusal, some kinds of violence and disrespectful attitude to teachers. On the other hand, handling difficulty students are selfishness, related with lack of attitude to listen to others and to work well with others, easily making fun of his/her friends and taking counterattacked attitude against teachers. Also teachers who answered that there were no handling difficulty students in his/her class were just twenty five percent. We discussed how to educate these hard handling students.
