Not graded but mandatory.
Right, but many high schools have mandatory service hours (do not underestimate how many high schools have various levels of service requirements). If it’s not on the transcript, I would put it in the activity section, as it is an activity, and community service/volunteer is certainly acceptable to include there. If it’s part of a titled course for high school credit on the transcript, that would be different.
I’m not sure how it benefits the applicant to emphasize in the app that the service is mandatory.
Also, as a matter of style, if she does end up putting it in additional info, I would say 400 hours over four years rather than 100/yr. Sounds bigger to me - just my two cents.
Yes, we found the best way was to include it under activities as community service, school organized. Thanks ever! So helpful. Happy New year to all.
