In education, a teacher is one who helps students or pupils, often in a school, as well as in a family, religious or community setting. A teacher is an acknowledged guide or helper in processes of learning. A teacher's role may vary between cultures. Academic subjects are emphasized in many societies, but a teacher's duties may include instruction in craftsmanship or vocational training, spirituality, civics, community roles, or life skills. Education encompasses teaching and learning specific skills, and also something less tangible but more profound: the imparting of knowledge, positive judgment and well-developed wisdom. The transmission of knowledge and skills from teachers or other competent sources to students.
