My institution is new to Turnitin, and on a number of occasions they've requested system admin access to our LMS, in order to troubleshoot a Turnitin-related problem (of which there have been more than I expected). So far, I have not given them that level of access. Do others give over system admin access? We don't really have a policy restricting such a practice, but it makes me very uneasy. I'd appreciate any feedback on how others handle this.
