Teacher, often known as a schoolteacher or an educator, is a person who assists pupils in the acquisition of information, competence, or virtue via the use of instruction.
Those who want to serve as teachers may do so informally . Education of young people of school age may take place in an informal environment, such as inside the family (homeschooling), rather than in a formal one, such as a school or a college, in certain nations. A considerable quantity of teaching may be required in several other occupations as well (e.g. youth worker, pastor).
Students' formal education is typically carried out by paid professional instructors in the majority of nations throughout the world. It is the primary emphasis of this article on people who are paid to teach others in a formal education setting, such as a school or other institution of first formal education or training.
