Why Not an Outside Contractor? Why didn't BLM use an outside contractor? Originally, it was thought that only an outside contractor could provide sufficient confidentiality for participants and their raters. However, as the National Training Center learned more about the capabilities of Lotus Notes, the Center realized that it could maintain the required confidentiality using this product. Once the person being rated enters his or her name into the LNAT, the documents created for the person can only be accessed by that person. No one else can read the documents including the program manager at the National Training Center.
