Team Associates are missionaries who receive funding from non-IMB sources. They are either self funded, which means they provide their own support from things like personal savings or an existing job, or they are ministry funded, which means they are funded from another organization or church. Team Associates can participate full time or part time in the missionary task.
Field Support personnel are missionaries who are fully funded by the IMB to provide a critical support service on behalf of the IMB in an international location. Field Support missionaries engage in the missionary task, but their primary responsibility is to provide a professional service and support to IMB missionary teams.
