It's popular for elementary school students in Taiwan to attend English supplementary education which provides compulsory education from age of 3 to 13. These English schools can be classified according to the age range of the pupils and the types of education provided. Basically, there are two types of English supplementary educations: infant and primary. Infant English education caters for age 3 to 6, while primary English education for ages 6 to 13. The latter can also be sub-divided into junior schools (for age 6-8) and secondary schools (for ages 8-9 or 9-12 or 13). According to their abilities, the pupils of secondary school may again be grouped and selected by means of an examination at the age of 10-13. There are three programs provided for the students to promote their English ability. The first program is that they may learn English by listening and speaking. And the second one is to read and write. The last one is that they may learn some of simple, easy grammar from the courses. It is the main reason for the parents in Taiwan to send their children to the professional English schools.
