Peer opinion leaders are students who set the trends. They define what is "in" and "out". They influence the opinion of others. Knowing who the natural peer opinion leaders in your class or group are is a key to setting positive norms and making anything you do successful.
Almost every peer group has an opinion leader. During early adolescence, girls will have their leaders and boys will have theirs. Some can be positive leaders while others may be negative. We tend to think we know who the peer opinion leaders are on our own. We sometimes see them as the class clowns, the most vocal or the most popular. These characteristics can be misleading. Not all peer opinion leaders have these traits.
