Like most things, this research had the benefit of input from many people. Most important, I wish to thank Karen K. Petersen for teaching me what it takes to do a creditable piece of research. I particularly appreciated the many questions you posed and the continued focus you provided. Thank you.
Don Schwartz's technical expertise in job evaluation and psychological measurement was invaluable. I would also like to thank Don for providing "psychological support" at key points. Dan Corts spent many hours explaining how the FES was first established. Joe Donovan introduced me to SAS.
I would like to thank Bea Edwards and Bobbie Spalter-Roth, of the Center for Applied Research, and Sam Freidman, Muriel Cantor, and Ester Chow from American University for their theoretical input. Lise Markl edited and re-edited the many versions and these were typed by Lona Pollard. Finally, I wish to thank my family: George, Herta, Diane, John, Vicki, and Yoko, who always wished me success.
