The aim of this study was to examine the impact of Reading for Ethiopia's Achievement Developed Community Outreach (READ CO) project intervention on students' oral reading fluency, reading comprehension, academic achievements, and listening comprehension. It also aimed at identifying the students and teachers' awareness and practices about the READ CO project interventions. Experimental research--Posttest-only control group--design was employed for the study, which is mainly quantitative, but also uses qualitative techniques (latent content analysis). The results were analyzed using t tests and econometrics analysis mainly. Questionnaires and observations were also developed and employed as other tools among the experimental group principals and language teachers in the school to investigate the overall practice. The results from quantitative data analysis indicated that there were no statistically significant differences between the posttest performance of the study group and the control group for reading comprehension, academic achievements, and listening comprehension, yet oral reading fluency is significant. The result from questionnaire and observation also showed that the project has not been found to have a positive impact on students reading performance or improvement. Finally, it was mainly recommended that practical training and real service should be given for the targeted schools on how to improve and implement reading practices via the project.
