Summarize this article for a 10 year old
Student–teacher ratio or student–faculty ratio is the number of students who attend a school or university divided by the number of teachers in the institution. For example, a student–teacher ratio of 10:1 indicates that there are 10 students for every one teacher. The term can also be reversed to create a teacher–student ratio.
Staff:child ratio is the number of children for whom each child care staff member (or family child care provider) is responsible for supervising.[1]
The ratio is often used as a proxy for class size, although various factors can lead to class size varying independently of student–teacher ratio (and vice versa).[2] In most cases, the student–teacher ratio will be significantly lower than the average class size.[3]
Student–teacher ratios vary widely among developed countries.[4] In primary education, the average student–teacher ratio among members of the Organisation for Economic Co-operation and Development (OECD) is just below 16, but ranges from 40 in Brazil to 28 in Mexico to 11 in Hungary and Luxembourg.[4]
