Abstract

This study examined the effects of performance appraisal methods on employee performance at NWSC in the Teso sub-region. The objectives of the study were to examine the impact of 360-degree appraisal method on employee performance at NWSC in the Teso sub-region, the impact of management by objectives appraisal method on employee performance at NWSC in the Teso sub-region, and the effect of Behavioral Anchored Rating Scale appraisal method on employee performance at NWSC in the Teso sub-region. The study employed a mixed-methods design, combining both quantitative and qualitative approaches. Structured questionnaires were administered to collect quantitative data, and interview guides were used to gather qualitative data. A sample of 98 respondents was obtained from the targeted population of 130 respondents using Krejcie and Morgan table of population sample determination. This sample population was selected using random sampling and purposive sampling techniques. The data collected were analyzed using the Statistical Package for the Social Sciences (SPSS), and descriptive statistics were generated. Based on the findings, the results revealed a positive and significant impact of the 360-degree appraisal method on employee performance (b = 0.206, p = 0.001, Partial R² = 0.11). Furthermore, the MBO appraisal method had a positive and significant impact on employee performance (b = 0.441, p < 0.000, Partial R² = 0.37). Lastly, the BARS appraisal method had a positive and significant impact on employee performance (b = 0.549, p = 0.001, Partial R² = 0.10). The descriptive and qualitative results indicated a positive and significant impact of these performance appraisal methods on employee performance. The study recommended that further research be conducted on the effects of performance appraisal on employee performance in other contexts, beyond NWSC and regions beyond the Teso sub-region.
