Work-search log: how detailed does it need to be? after 11 years as a school bus driver

The certification asks how many work-search activities I did and I do not know what qualifies. There are 11 people counting on me, so I am trying to be careful. I also did a résumé workshop at the library. Do interviews and workshops count?

I was asked for my log once, after six months. Having it in a spreadsheet made it painless.
