School Teacher from WikiPedia:

In education, a teacher is a person who educates others. A teacher who educates an individual student may also be described as a personal tutor. The role of teacher is often formal and ongoing, carried out by way of occupation or profession at a school or other place of formal education. In many countries, a person wishing to become a teacher at state-funded schools must first obtain professional qualifications or credentials from a university or college. These professional qualifications may include the study of pedagogy, the science of teaching. Teachers may use a lesson plan to facilitate student learning, providing a course of study which covers a standardized curriculum. A teacher's role may vary between cultures. Teachers teach literacy and numeracy, or some of the other school subjects. Other teachers may provide instruction in craftsmanship or vocational training, the Arts, religion or spirituality, civics, community roles, or life skills. In some countries, formal education can take place through home schooling.
