Decisions are made on a consensus basis. If anyone on the team has an objection that can be resolved through follow up questions to the nominee, that person is not selected. Some people are rejected on the basis of information the team members have about their work beyond the nomination form.
We also based rejections on the reasons the person was nominated. Sometimes someone would be nominated just because she/he works hard, but the nominator had no idea about the impact of the person’s work or how the youth felt about that work. We would sometimes ask nominators for more information if something wasn’t clear.
