Academic Resume Year vs. Grade Level?

<p>On an academic resume, is it better to include the grade level(s) or the year(s) in which you participated in an activity?</p>

<p>For instance, if I were in National Honor Society my junior year, would I put something like:</p>

<p>National Honor Society (11)</p>

<p>or should it be:</p>

<p>National Honor Society (2012-2013)?</p>

<p>The same question applies for various years: if I were in National Honor Society my junior and senior years, would it be:</p>

<p>National Honor Society (11, 12)</p>

<p>or:</p>

<p>National Honor Society (2012-2013; 2013-2014)?</p>

<p>The latter seems wordier but I've heard that it's more appropriate. Is this true?</p>

<p>Thanks</p>
