In The Church of Jesus Christ of Latter-day Saints, the word teacher has two meanings:
- An office of responsibility in the Aaronic Priesthood generally held by young men ages 14 to 15. Teachers prepare the bread and water given during the sacrament (similar to communion) at Sunday worship services. These young men may also serve as home teachers and visit members in their local congregation. In local congregations, teachers are organized by quorums. These small groups allow young men to learn leadership skills as they serve together, have activities and help each other live the gospel of Jesus Christ.
- A person who teaches a Church class. This may include classes for children, youth or adults. These classes are usually taught as part of Sunday worship services with the purpose of strengthening personal faith and increasing knowledge of the scriptures and Church doctrine.
