SDN Members don't see this ad. (About Ads) I didn't see a thread created for Colorado yet so I figured I'd start one for my question. Umm...so what's with this new ETS-PPI (personal potential index)? Are they telling me now that not only do I need to harass my LOR writers to write but also to fill out this silly survey? I'd like to know how long it is so that I know what I'm signing my people up for. Is this just ridiculous or what? Anyone know of any other schools who are using this service this cycle?
