How are volunteer hours figured?

Do you consider all four years? Add Middle school? How do you list this on say, the Coalition Application? Is it per volunteer activity? Or as a block of hours accounted for in the description? Do some colleges have their own application or supplemental application line item for only volunteer hours? Thanks in advance for helping me clarify. My son will have about 200 hours (over 4 years) , but not in all one activity so I’m not sure how to account for it.

He lists all years in HS in which he participated

No

I can’t speak for the Coalition App, but the Common App lets the applicant choose Summer/Academic Year/Fall Semester/All Year, etc. You son can apply an average number of hours per week across the selected time frame.

In general, no, but there may be an exception.

It’s his choice to list the activities separately or lump them all together. Neither you nor he should overthink this; it’s not that critical so long as the number of hours does not appear to be outside the realm of reason.
