@roger,
This is for high school so it would be used for applying to college not really for an employer. It is supposed to be exclusive where you can't just be a good student academically, but you need to demonstrate that you also excel in community service, activities outside of schoolwork like athletics, band, or other clubs and organizations and have demonstrated leadership skills.
Basically a very well rounded leader. So you apply and if you get in then you also participate in this organization by helping in various community service and or lead these types of projects.
It wasn't this intense when I was in high school, but to be honest everything seems more intense in high school now.
I was in an international honor society in graduate school, but I did nothing .... other than my grades ... I didn't even know anything about until I got a letter congratulating me on the accomplishment. One of my professors nominated me..probably nominated everyone that met whatever the criteria was.
I did put it on my resume. Why wouldn't you put a major accomplishment on a resume? And often times job applications have a spot to put such accomplishments in. I have never been laughed at by an employer for this. And I've seen such things on resumes of interviewees.
