The Missionary Training Center for members of The Church of Jesus Christ of Latter-day Saints (aka Mormons). There are MTCs all over the world, including Utah, Brazil, and Europe. LDS missionaries are immersed in a 6-10 week program that teaches Church doctrine, and, depending on where the missionary is headed, culture, language and English teaching. The main MTC is in Provo, UT on Brigham Young University campus.
