The aim of the study was an assessment of monitoring & evaluation practices on the project performance of NGOs in Rwanda. The study was guided by three theories: The theory of change, community action planning (CAP) theory & dynamic capabilities theory. The specific objectives underpinned were: - to find out the relationship between monitoring & evaluation practices on project performance of NGO projects in Rwanda. The study employed descriptive and correlative approaches. The target population was 116 people while the sample size was 90 respondents. Data were collected using the questionnaire and documentary instruments. Techniques used to analyze data were descriptive statistics, Pearson correction coefficient& Regression Analysis Model. 

Findings indicated that the correlation matrix indicated that the sum of Pearson Correlation(588**); with a p-value of which is 0.01 that less than 0.00, meaning it was a significant positive and significant strong correlation between monitoring and evaluation practices M&E plan, develop M&E tools (.190), Meaning a unit increase provide (19%) on NGOs projects Performance whose effect was(.117), while Gathering M&E data (.146), a unit increase provide(15%) on NGOs projects Performance, it had the effect of(.098), Analysis of M&E data (.049) a unit increase provided(4.9%)being the lowest contributor, while M&E reporting .251 a unit increase provide(25%) on NGOs projects Performance and lastly Use of M&E data .929, Meaning a unit increase provided (.93%) on NGOs projects Performance being the highest contributor, with a strong effect(.432). 

Conclusion: findings indicated that the Use of M&E data Means a unit increase was the highest contributor on overall as a constructor it also posted the highest effect. A  strong man with evidence that there was a heterogeneity of responses that confirmed TAMTF used different M&E practices to stimulate NGOs Projects performance at Kicukiro District. The achievement of a positive and significant strong correlation between monitoring and evaluation practices indicated an uprated mitigation of NGOs projects Performance. 

Recommendation: The NGOs should consider making use of forecasting to determine the type of projects to pursue and assess the potential of the ongoing projects. The use of Log frames will help to propel a link of project goals, hence or otherwise the future objectives will mandate the inputs/outputs required for effective project implementation.
