Our purpose with this study was to investigate whether there was any difference between high and low performing students from selected aspects such as choice of studies, achievement, self-image, motivation, confidence and career choices. A training professional in today's schools requires knowledge of how young people think about their lives for us to help students develop both high-and low-performing students. Students have different conditions, but no matter good or bad conditions, each individual pupil must be allowed to develop. The concepts used in the study are of study, self-image, motivation, achievement in the future and career choices. In the background, describes these concepts through literature study. The method we have used was semi-structured interviews. Which means a fixed structure, but with room for follow-up questions. The results of our study indicate that there were clear differences between high-and low-performing students. The differences suggest that the high-performing students were more conscious about their study options than low-performing students. Differences were also in the students' views of themselves,where the high-performance had a lower self- image than the low-performing students had. High performance compared each other more often with other people and was more unsure of themselves, however, the motivation was significantly higher among the high-performance students, performance showed the same results. The high-performing students had a clearer vision of the future and that they had a clearer picture of their career choice than the low-performing students. Discussion on how we as educators can strengthen each student based on their individual needs have been based on results of the study.
