Peer Review - GCSE Biology Definition

Peer review is the process where scientists check each other’s work to make sure it is accurate, reliable, and meets scientific standards. In GCSE Biology, this means that when a scientist reports new findings, other experts in the same field examine the methods, data, and conclusions. They check for errors, suggest improvements, and ensure the research is valid before it is published. Peer review helps prevent false or misleading information from being shared and maintains the quality of scientific knowledge.
