Since the Bologna reform a continuous improvement of the lessons’ quality at school, which is often connected with the professionalization of the future teachers and the teaching post education, is aimed by Alliance and federal states. The quality of the lessons is connected with the professionalization of the future teacher and the teaching post education. In most studies about quality improvement the consideration occurs predominantly from the university view and it is seldom related on the subject Sport. The quality study is established on these two points and leads to the main question: Are there any differences in the teachers‘ and learners‘ perceptions of the professionalization of sport teachers in the certain education phases in Rheinland-Pfalz? With the help of 101 guide interviews and the evaluation according to the Grounded Theory this source question can be answered straight. There were interviewed teachers of the universities, of the state study seminars and the school, as well as learners, to that refer trainees and students. During the study the „missing school relation” crystallizes consistent in all personal groups as key element (core category) in the first and second education phase. The interviewed, which belong to different school forms, give relevant concrete, specific for sport and partially subject covering optimization proposals. As a result a main focus forms untimely relations to the school everyday life and at the same time collect teaching experiences with learning groups at school to get to know their different motor abilities and skills. The improvement approaches concern the university phase and the training period in the study seminars and schools, and the involved consider for necessary a more intensive interlinking of the individual institutions. A mutual, continuous cooperation for the professionalization in the sportsman's education and therefore the optimization of the sports teacher training is very important for all involved.
