This study aims to find out traniee primary school teachers levels of the use of teaching principles. At first, essential teaching principle and their requirements for the lessons have been identified from the literature. To that end a special questionnaire has been developed for the research to identify the level of the teaching competence in the light of the reviewed literature. This questionnaire has been applied to the mentors and observers. Later, findings have been analysised as statistical. According to the observer students the results of analysis have indicated that the traniee teachers’ most sufficient teaching skill is “asking questions to the students and have them think on these questions”. “Summarising the lesson when needed and getting students to take note” are the weakest skill of the trainee teacher. According to the observer teachers the most sufficient skills of the trainee teachers are “that students are satisfied with what the trainee teachers have said and done”. Similarly, the weakest skills of these students are “making a general summary at the end of the lesson”, explaining the lesson in line with the lesson plan and the use of time properly”.  Further more, it is suggested that the lecturers of education faculties must spend more time and effort in teaching the applied courses and this will contribute to traniee teachers knowledge of teaching principle.
