This study aims at revealing how teachers of partner schools perceive their training of pre-service teachers’ teaching practice and what implications could be provided for the teaching practice policy direction. Survey research was used with a questionnaire developed by researchers. As for data analysis, independent-samples t-test, one-way analysis of variance (ANOVA), the Scheffe post-hoc test, and multivariate linear regression were conducted. The study findings are as follows. Firstly, teachers mainly perceive teaching practice as a pre-experience of teachers’ educational activities, on the one hand, and a process to learn and formulate the competencies required to be a teacher, on the other hand. Secondly, improving professionalism in teaching is recognized less positively than the degree of satisfaction in teaching practice guidance of both trainees and trainers, while their training of teaching practice is positively perceived to be effective. Thirdly, the degree of satisfaction of both trainees and trainers in the training is positively affected by the way of the lesson plan to be guided. However, both “training on school administrative affairs” and “teachers’ meeting after classroom instruction” influence more positively improving professionalism in teaching than lesson plan guidance according to the linear regression analysis. Fourthly, providing a manual for the training of teaching practice is perceived to be the most prioritized. Also, primary school teachers think “teaching practice evaluation to be reflected upon the selection process of teacher recruitment” is at a higher level than that in middle schools.
