Using the Bulk Update feature in the training record helps to reduce the time and workload spent in keeping this up to date. 

Select the training subject to be updated and then open Bulk Update.

You can select all staff, user groups or type search staff names to be included. Check training required and the form expands to include last trained and scheduled training dates as well as the option to upload certificates or files. Remember to save and you see that all staff have the record updated.
