Answer:
school is an educational environment where people, particularly young children go to learn about topics such as reading, writing and mathematics from a teacher. Most of a student's time will be spent in a classroom, a place where usually 10 to 30 people sit in to engage in educational discussion. In the United States, the average of students per classroom during primary school is 23.1.[1] The term "school" is used for many educational environments--particularly in North America. There are different types of schools: elementary schools (primary in the UK), middle schools (secondary in the UK), and so on.

In many places around the world, children have to go to school for a certain number of years. Learning may take place in the classroom, in outside environments or on visits to other places. Colleges and universities are places to learn for students over 17 or 18 years of age.[2] Vocational schools teach skills people need for jobs.
Some people attend school longer than others. This is because some jobs require more training than others, like for example becoming a doctor takes about 10-14 years of education.[3] For young children, one teacher may teach all subjects. Teachers for older students are more specialized, and they only teach a few subjects. Common subjects taught include science, arts such as music, humanities, like geography and history, and languages.
Children with mental issues and problems such as autism and other illnesses which make the child difficult to handle are not required to go to regular schools. These children are given other ways to get schooling, like special education schools. There also are special schools which teach things which regular schools do not.
