Hi all -
If you're using Resource Scheduling to manage your volunteer schedule, you could use Worker Resource Qualifications to track this. A qualification could be added all workers who have passed the background check. Qualifications can optionally include valid dates in case these checks need to be re-run after so many years. Then, you'd include the qualification when selecting a Worker for the booking. Only those who have the Qualification will appear as available.
Thanks,
Patrick
