This study examined the influence of performance appraisal systems on employee motivation in selected ministries of Delta and Rivers States, Nigeria. The research focused on five performance appraisal dimensions: Traditional Performance Appraisal Systems, 360-Degree Feedback Systems, Management by Objectives (MBO), the Critical Incident Method, and Ranking and Paired Comparison Methods. The study was motivated by the need to understand how different appraisal practices affect motivation and performance within the public sector, particularly in an environment where efficiency, accountability, and service delivery are critical. A cross-sectional research design was adopted for the study. The population comprised 30,500 public service employees drawn from selected ministries in Delta and Rivers States. Using the Gill and Johnson (2010) sample size determination table, a sample size of 652 respondents was selected. Data were collected through a structured questionnaire, of which 537 copies were correctly completed and deemed suitable for analysis. The data were analyzed using descriptive statistics, Spearman’s correlation, and multiple regression techniques to test the study’s hypotheses at a 5% level of significance. The findings revealed that all five performance appraisal systems examined had positive and statistically significant relationships with employee motivation. Traditional performance appraisal systems were found to enhance motivation when appraisal processes were clear, fair, and consistently applied. The 360-degree feedback system showed a strong positive influence on motivation by promoting fairness, accountability, and comprehensive feedback. Management by Objectives emerged as the most influential appraisal method, significantly enhancing motivation through participatory goal-setting, clarity of expectations, and measurable performance tracking. The Critical Incident Method positively influenced motivation by focusing on key job-related behaviors and timely feedback. At the same time, the Ranking and Paired Comparison Methods also contributed positively by encouraging recognition and healthy competition among employees. The study concluded that effective performance appraisal systems are vital tools for enhancing employee motivation in the public sector. It recommended, among other things, adopting a balanced, integrated appraisal framework that combines traditional and modern approaches to improve motivation, accountability, and overall organizational effectiveness in public service ministries.
