Your evaluation will likely come from a variety of sources.
Your mission agency team leader will likely conduct an official annual evaluation. He or she will probably be asked to account to a country or regional leader above him/her as to your team members and their joint effectiveness.
Your sending church should want to evaluate you through an annual evaluation. Such an evaluation should include questions regarding your work’s goals, your achievement of those goals, your spiritual health, your family’s well-being, and how it can pray for you. Your sending church should ideally personally respond to your report.
Your supporters are passive, rather than active evaluators. Your communication with them should reflect your primary goals and tasks, and progress you’re making in the ministry. They may choose to ask you questions about the ministry and offer feedback.
