Hi Sarah Jane

If you choose the option Save Certificates then a copy of each student's certificate is saved in the course files moddata folder for that certificate.

There is also an option under delivery to email the certiifcate to the student. This needs to be chosen in conjunction with the Save Certificate

A link to each student's saved certificate will be displayed in the trainers "View Issued Certificates" report with a link to the file. (as in the screen below)
