I was hoping we could get a list going of Industry Certifications.

The biggest, of course, is NABCEP.
Underwriters Laboratories (UL) has a Certified PV System Installer.

Those are the only two independent certifications that I know of (though I thought there was a third). Then there are two other categories of training: manufacturer and technical schools/colleges. I don't really want to get into the latter. Most manufacturers provide some sort of webinar or basic training to some extent, but the companies that I know of having more extensive training/certification programs are Sunpower University and SMA Solar Academy. Also, Multi-Contact has a simple, free online certification for connector assembly (i.e. MC-4). What else is out there?
