American education is mainly provided by the government, controlled and funded by the federal government, state government and local government (school district). In primary and secondary schools, policies such as curriculum, funds and teaching are decided by the local elected school district committee. According to officials and budgets, school districts are usually separated from other local affairs. Educational standards and standard tests are usually set by state governments. In America, 16- 18 years old must go to school. Now many states require students to study until they are 18 years old. Some states only stipulate that you must study until you are 14 years old. Students can attend public schools, private schools or home schools. In most public and private schools, education is divided into three levels: primary school, junior high school and senior high school. In a United Nations education index of 2 1 country, the United States scored 99.9, ranking first in the world [4]. 76.6 million students are in grade 16. Among them, in the compulsory education stage, 5.2 million people (10.4%) attended private schools. Of the adult population in this country, 85% graduated from middle school, and 27% obtained a bachelor's degree or above. According to the statistics of the US Census Bureau in 2002, the average annual income of college graduates is $45,400, which is 10000 $ higher than the average level. The literacy rate of the population above 0/5 in this country/kloc-is 98%. Education is an important issue in Japanese society. Generally, there are three types of education to choose from: the first is to enter public schools for compulsory education, enter private schools for compulsory education, or go to private schools that do not meet the standards of the Ministry of Education, Culture, Sports, Science and Technology. Although compulsory education only lasts until graduation from middle school, more than 90% of students will enter institutions of higher learning. More than 2.5 million students will go to universities or colleges for further study. In the past, entering higher education was described as "hellish" and "war-like". However, due to the declining birth rate in Japan in recent years, there are fewer and fewer school-age children, and this phenomenon has begun to change. Now schools are competing to recruit new students. However, many students are sent to cram schools outside the normal courses.
