What are the reasons for recruiting trainee teachers in technical secondary schools?

Secondary technical schools are short of teachers.

For trainee teachers, in the process of changing from new teachers to mature teachers, their own professional core literacy is the premise and guarantee for successfully realizing the role change. Among all professional core qualities, classroom teaching ability is the most important. "Teaching ability is the synthesis of personality characteristics, knowledge, skills and attitudes necessary to support teachers to effectively carry out teaching activities in various teaching situations."
