This study examined the combined and relative effects of performance appraisal system, training and reward management on work efficiency of university non-academic staff. Two hundred and forty randomly selected non-academics from three universities in Ogun State, Nigeria took part in the study. The age range of the participants was between 23 and 57 years with mean age of 31.6 years while the standard deviation was 9.17. The data for the study were collected using a self-developed questionnaire with three subscales on performance appraisal, in-service training and reward management; while participants’ annual performance evaluation report was used in generating data for work efficiency. Two major hypotheses were formulated and analyzed using multiple regression statistical procedure tested at 0.05 alpha level. The results indicated that the predictor variables when combined accounted for 40.3% of the variation in employees’ work efficiency (R= .641; R2 = .411, Adj R2 = .403; F = 38.404; P = .000). Performance appraisal proved to be the most potent predictor of employees’ work efficiency (β= .458; t= 4.501; P < .05), followed by reward management (β = .321; t= 2.866; P < .05). In-service training has the lowest potency power (β = .390; t = 3.478, P < .05). Based on the findings of this study recommendations were made
