This study examined the extent to which Primary Schools of Fagita Lekoma Woreda implement teachers' CPD and its impact to quality in education. Data were collected from teachers, school principals, and woreda education office supervisors. Questionnaire and interview were used as the data gathering tools of the study. The quantitative data was analyzed using percentage and one sample t-test. The qualitative data was analyzed via thematic description. The findings confirmed that the respondents' level of agreement regarding the implementation of teachers' CPD was found significantly greater than the expected mean (3) in some parameters of the implementation of CPD (e.g., teachers' access to new ideas (3.48), teachers' state of sharing experiences (3.44), and teachers' professional interaction (3.48)). But, there was no significant difference between the expected mean (3) and the calculated means of the other parameters (e.g., attention given for teachers true learning (3.15), focus on staff professional development (3.10), pursuit for improved teaching and learning (3.06), teachers' engagement into continuous professional development (3.31), the match between professional development provision and professional needs (3.08), conceptualization of professional development (2.92), being insensitive of matching of staff development opportunities to individual concerns (2.75), effort made to relate learning experiences to work place conditions (2.88), and teachers' engagement into professional development that promotes inquiry, creativity, and innovation (3.04)). The aggregate calculated mean value of extent of CPD implementation (3.14) also showed insignificant difference from the expected mean (3). Moreover, it was confirmed that there was no significant difference between the expected mean and the calculated means of all the parameters of the impact of CPD implementation on quality in education of primary schools of the woreda. Having considered the above major findings, relevant recommendations were forwarded in the recommendation section of this article.
