The British System of Education
Read the text below. Match choices (A-H) to (7-12). There are 2 choices you don’t need to use. Write your answers on the separate answer sheet.

The British system of education suggests several types of educational establishments to fit every parent’s requests and possibilities. Here are the main ones.
State schools are maintained by local authorities. They are usually free to be attended by all children aged 5-16. Parents are expected to provide their child with necessary office supplies, while all the books and other equipment are covered by the school. Sometimes school uniform and sportswear are also bought by parents. Besides, schools may ask for voluntary contributions to hold after-school activities, but any child can participate no matter if his or her parents agree to donate. 90% of children in the UK go to state schools.
About 88% of secondary-school students attend comprehensive schools. These schools teach children of all abilities and provide a wide range of secondary education for pupils aged 11-16.
Grammar schools are fully selective and they are academically oriented. Entrance is made based on the results of the ability test, usually at the age of 11. Grammar schools are mostly single-sexed ones and this is their other distinctive feature.
Boarding schools in the UK teach a mix of international students and locals. “Day pupils” leave school at the end of a school day and live with their families. However, most pupils live at the school. Boarding schools are usually co-ed ones with separate accommodation and mixed classes. Boarding schools are usually co-ed ones with separate accommodation and mixed classes. Boarding schools could be both private and free-state ones, which only demand a charge of boarding accommodation, although the free-state boarding schools accept UK citizens or pupils from the European Academic Area only.
A parochial school is a private educational establishment of primary and secondary levels which is affiliated with a religious organization. Its curriculum usually includes general religious education in addition to common subjects such as maths, language and science.
Special schools for students aged eleven or older usually specialize in one of the areas of special educational needs. These include social, emotional and mental health; sensory and physical needs; cognition and learning or communication and interaction. Such schools often further specialize within the main categories to reflect the special needs they help with like Autistic spectrum disorders or any other of a kind.
