Peer review is a rigorous evaluation process used in academia to assess the validity and quality of research articles before they are published. It plays a crucial role in maintaining the integrity and improving the overall quality of published research. Through peer review, independent experts in the relevant field carefully evaluate the research being presented. This process helps to ensure that only high-quality and original research is published, and it also provides opportunities for networking within the academic community. Essentially, peer review acts as a form of quality control for published research and involves subjecting a manuscript to the scrutiny of experts in the same field. Overall, it is an integral part of the academic publication process, helping to maintain standards and advance the knowledge in a particular field.
