If an Administrator has enabled time-tracking in VS, you can track the hours volunteers work on the opportunities they are matched to. Volunteer hours can be logged by volunteers themselves by submitting a claim for hours worked on a particular opportunity, which you will have a chance to review and approve before they are posted in VS. You can also log hours for a volunteer using the referral record that matched him or her to the opportunity, and/or by using the Hours tab of your Agency account.
The Hours tab offers sorting and filtering tools (the clickable column headings in the table of entries and the Filters section above it) to help you find specific hours-log entries and/or manage large numbers of entries. You can use the Hours tab to edit and/or delete hours-log entries of volunteers, as well as download records of volunteer hours.
