The nomination process is an eight-month screening and decision-making process.
In practice, the nomination process is an eight-month screening and decision-making process involving not only the five-member Norwegian Nobel Committee and its Secretary but also a group of Norwegian and international advisers. The advisers, selected on the basis of their professional experience and academic expertise, prepare individual reports on the candidates that the Committee has put on its short-list. The initial reports are usually ready by the end of April. The Committee members then study the reports together with other relevant information and start their deliberations. More often than not they will ask for further reports on various candidates. As they continue their deliberations throughout the summer and receive additional reports from the advisers, they narrow the field of candidates down to a very small group.
Eventually, by the beginning of October at the latest, the Committee makes its decision through a simple majority vote. The decision is final and without appeal. The name(s) of that year's Nobel Peace Prize Laureate(s) is then announced. The cycle is completed on 10 December, when the annual Nobel Peace Prize Award Ceremony takes place in the Oslo City Hall. At the ceremony, the Laureate(s) delivers the Nobel Lecture and receives the Nobel Medal and Diploma as well as a document confirming the prize amount.
