Peer review

Peer review is a process that people use to make sure things are done properly. It means that different people look at and check something before it is finished to make sure that it has been done correctly. In science and research, peer review means that experts in the same field look at an article or other work and give their opinion about it. This helps to make sure that the research is reliable and accurate.
