The general objective of this research is to assess monitoring and evaluation on construction project performance in Rwanda, case of Musanze and Rwamagana Asphalt road Project. The specific objectives were to assess the extent to which project budgets contribute to project performance of Musanze and Rwamagana asphalt road project, to determine the contribution of project risks analysis on construction project performance of Musanze and Rwamagana asphalt road project, to determine extent to which project trainings and accountability contribute to project performance of Musanze and Rwamagana asphalt road project and to determine the relationship between monitoring and evaluation on construction project performance. Thus, a description research design was used and the target population of the study was the project contractors, project engineers and project human resource officers. In total they were 210 from which a sample of 138 were selected as sample. A simple random sampling technique was used to select respondents and data were collected using questionnaire and interview. Analysis of data was done through SPSS (Statistical Package for social Science) version 20. Research findings showed that project budget was per planned to meet operating activities of the project. This was determined by mean score of 1.670 and standard deviation of 0.756. As indicated, the study findings showed that project budget varies from 5-10% of the entire project budgets as indicated by mean score of 1.636 and standard deviation of 0.734.Based on research findings provided in two selected projects, the were efficiency and effectiveness and reliable as respondents had the common understanding. The results showed that project has meet timelines operations of construction. This was confirmed by respondents at the mean score of 1.751 and standard deviation of 0.732.Findings showed that project trainings and accountability of project personnel led to quality assurance of projects operators as this confirmed by respondents at the mean of 1.446 and standard deviation of 0.616. Results showed that there is a positive correlation between Monitoring and evaluation and construction project performance where project cost effectiveness has a positive correlation at (r=.811, p=0.024), expected quality standards had a positive correlation at (r=.947, p=0.019), project time schedule (0.772, p=0.053) while beneficiary satisfaction (r=.819, p=0.064). As recommendation, researcher recommend to put more focus on undertaking appropriate monitoring and evaluation practices to achieve effective construction performance.
