Education in the United States


There is no
federal educational standard in the USA. Schooling and educational programmes
are the responsibility of each state; this is why one can find great
differences in education from state to state. No uniform demands exist on
education in schools or universities through-out the nation. In most states
attending school is obligatory for children between six and seventeen.
Secondary education institutions include elementary schools and high schools.
Higher education in the USA is not nation-wide. Colleges differ a lot from each
other in scale and level of education as well as in the "quality" of
diplomas given. There are private and state universities. Private education is
considered more prestigious. The most famous private university is Harvard.
Higher education is rather expensive in the USA.A typical American university has two levels of education: two years of undergraduate classes and two more years of graduate
classes. The undergraduate years are called the freshman and the sophomore
year. During the first and the second year the students take subjects of general
education: Science, Humanities, Arts. The specialization begins at the third
and the fourth years, named the junior and the senior year respectively. After the
fourth year at college, students get a Bachelor's degree. Graduates may
specialize further and do research. They get a Master's Degree.
