Junior high school is the primary stage of middle school. Generally, junior high school lasts for three years, and in some areas it lasts for four years (compared with five or six years in primary school), including senior one, senior two and senior three. Some areas call it Grade Seven, Grade Eight and Grade Nine. In Taiwan Province Province, junior high school students are equivalent to those in Chinese mainland. Junior high school is the beginning of adolescence, the last three years of nine-year compulsory education and a stage of transition to senior high school.
Junior high school is a part of compulsory education, usually starting from the sixth grade of primary school. The policy of primary school entering junior high school is defined by the district and county education committees, which mainly includes the examination policy and computer allocation policy in some counties and cities. Junior high schools are divided into key schools and ordinary schools, and some schools also have key classes (also called experimental classes) and ordinary classes. Most junior high schools have three years, that is, grades 7, 8 and 9 (grades 1 to 3), regardless of arts and sciences. Generally speaking, learn new knowledge in the first two years, prepare for the senior high school entrance examination in the third year, and then enter high school, technical school or vocational high school.
Following the British middle school system, junior high school has a three-year academic system (Form 1 to Form 3), and the courses are mainly extensive: many subjects are only taught in junior high school, such as music, art (only a few students will enroll in high school music and art courses), comprehensive science (high school science will be divided into physics, chemistry and biology), and most schools will teach carpentry/metalworking and housekeeping. The junior high school curriculum of industrial schools will reduce subjects such as geography and western history and teach design, technology and industrial drawing instead. After that, I usually go to a two-year high school (Form 4 to Form 5). After passing the Hong Kong Certificate of Education Examination, they can attend the two-year preparatory course, take the Hong Kong Advanced Level Examination and go to university. However, from September 2009, the curriculum of senior high schools in Hong Kong will be changed to a three-year system, and senior high school students will eventually take the Hong Kong Secondary School Diploma. The existing two public examinations will be officially closed after the last examinations on 20 1 1 and 20 13 respectively.
There is no fixed academic standard, which is decided by each school. Generally, the first three years of secondary education after primary school are regarded as junior high schools. Schools that have access to the Internet enjoy government subsidies free of tuition and miscellaneous fees. Non-online schools will be subsidized by the government.
