"Peer reviewed" means that a resource, commonly a journal article, is:
• Published in a legitimate journal
• Written by experts
• Reviewed by experts in the field
• Well-researched
• Contains accurate, substantiated information
• Contributes to the body of knowledge in a field
Using peer-reviewed articles means you already know that the research is credible and reliable and you should only need to determine if the content is relevant to your assignment.
While peer-reviewed journal articles are always scholarly, scholarly journal articles are not always peer-reviewed. You may be directed by your unit coordinator to only use peer-reviewed journal articles (in amongst other types of material) in an assignment. If not, you can definitely use scholarly journal articles that have not been peer-reviewed, but you must ensure you evaluate them.
Look for the peer-reviewed icon in Library Search to identify peer-reviewed articles:
