Primary teachers are responsible for guiding children through the formation of many important life skills, and also watching over their students’ social development. Primary teachers come into contact with about 30 students every day, and teach them a variety of subjects. Many hours are spent before and after class on planning, preparation and correction. One should be a very patient, caring, yet firm person to be able to deal with the demands of children in the four to twelve-year-old age group.

Secondary teachers teach specific subjects to various groups of students. Just like primary teachers, they spend an amount of time planning and preparing lessons and correcting homework—their duties are not restricted to face-to-face teaching. Dealing with twelve to eighteen-year-olds requires a wide range of skills.

If you become a primary teacher, you will need to decided whether to be a “generalist (多面手)”, teaching a wide range of subjects, or a "specialist", teaching only one or two. Most primary teachers are specialists. Generalist teachers spend the greatest part of their day with one class, which means that they spend more time with the same children. Specialist teachers have more time away from their students. It is therefore very important for generalist teachers to develop a strong working relationship with their students.

The unique rapport (和谐) you can develop with a particular set of students is one of teaching’s greatest pleasures. However, the disadvantage of primary teaching is that if you have a difficult student, you will be forced to deal with him or her, all day, every day, throughout the school year. Teachers need to work out strategies to get themselves and their students through such difficulties.

Primary teachers today are generally four-year trained. They usually do a three or four-year undergraduate degree, and if this degree does not include teacher training, they will have to undertake postgraduate study in education as well.
