This research identifies variables affecting the length of time to pro
cess a soldier through the U.S. Army Physical Disability Evaluation Sy
stem (PDES), The subjects are 8,301 soldiers whose disability records
were processed in fiscal year 1996, The dependent variable examined wa
s the average number of days a soldier remains in the disability proce
ssing system. Independent variables included age, component, compensat
ion award, Congressional involvement, gender, grade, retirement eligib
ility, race, length of service, formal Physical Evaluation Board (PEB)
, and regional FEB. Statistical analysis using linear regression and S
PSS yielded an average length of stay (ALOS) of 155 days and a range o
f 1 to 2,052 days, The research shows that the most significant variab
les affecting ALOS are Congressional involvement, component, compensat
ion, formal FEB, and regional FEB. The authors recommend a program of
disability case management and increasing emphasis on transition assis
tance programs to reduce ALOS in the PDES.
