<p>My son had to track volunteer hours for National Honor Society and for IB program. Beyond that, I did keep a resume of accomplishments (w/o) hours. He was too modest to do it himself, but it sure helped when filling out college apps.</p>
<p>Common App asks students to list activities and estimate hours per week and weeks per year. Sometimes you need to just make a ballpark estimate where the activity is not constant. I suppose you could put a general “volunteering” category if needed.</p>
