In this study, we introduce what kind of role is played by psychological immunity and its sub-factors and its factor values in life of the students taking part in the professional training, in their performance at school, in the improvability of the students' strengths and weaknesses. The target of the research is to renew the methodology of the professional training through becoming acquainted with the students of the new generations more exactly. Since, the new generation has changed and it is still changing even today. Their education-training is getting more and more difficult because we do not know them enough. Teachers say that the knowledge of the students, the level of their education, mainly in the specialised secondary schools, is very low because the series of their failures can be detected and the non-attendance is also typical. Much of the students do not have any relevant prospect for the future after the specialised secondary school; they do not have any targets in the long run. The teachers in the specialised secondary schools observe that students are disinterested, they miss persistence, their control ability is very low, the EQ is decreasing and their self-knowledge is imperfect. All of them can be the source of conflicts.
