Church planting movements happen when Christians (both foreign and nationals) spread the Good News of Jesus in a culture with little to no access to the Gospel of Christ. Several mission organizations teach church planting (sometimes using different names for the same thing), but in Youth With A Mission (YWAM), the program is called “Disciple Makers Increase”. It’s part of YWAM’s Frontier Mission course offerings. You can learn more here: Link
