Nope. The SLOR IS your LOR (hence, S-LOR). It doesnt' leave too muhc room for comments but the PD's prefer the SLOR to a letter anyways (plus its easier and quicker to read). I had two of my EM attendings fill out my SLOR, and the rest of my LORs (Trauma Surgeon, Pulmonlogist) were regular old letters.
