Teachers provide formal education to students in schools and other educational institutions. They facilitate learning through lesson plans that cover standardized curricriculums. A teacher's role may involve teaching subjects like literacy, numeracy, sciences, arts, or vocational skills. Obtaining professional qualifications from a college or university is often required to become a state-funded school teacher. Informal learning can also be assisted by family members or others in the community. Religious teachers facilitate the study of religious texts in spiritual education.

1. In education, a teacher is a person who provides schooling for others. A teacher
who facilitates education for 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
who wishes 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 will
have to continue their education after they receive their degree from a college or
university. 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.
Informal learning may be assisted by a teacher occupying a transient or ongoing
role, such as a parent or sibling or within a family, or by anyone with knowledge or skills
in the wider community setting.
Religious and spiritual teachers, such as gurus, mullahs, rabbis pastors/youth
pastors and lamas may teach religious texts such as the Quran, Torah or Bible.
