Mark,
I actually am getting audited. I am wondering about the unofficial transcript because my diploma is currently framed, and I would prefer to not have to take it out of the frame. Per the audit guidelines, I think the following excerpts are germane but do not lend enough specificity for me to determine if an unofficial transcript will be sufficient:
{from Audit PM Experience Records section}
Audit Requirements:
To meet this requirement for the audit, a copy of your degree or transcript from the educational institution where your Bachelors, Masters, or PhD (or global equivalent university degree) was earned is required.
...
{from Audit FAQs section}
Will PMI accept a school transcript to meet the degree requirement?
Yes.
If a certificate is in a professional frame, does it need to be taken out?
The degree does not need to be taken out of the professional frame. If it is too large to photocopy, please submit a transcript.
I think to be safe, I'm just going to take the diploma out of the frame and photocopy it because there does not seem to be a clear-cut answer based on PMI guidelines alone.
Best,
Mike
