The major objectives of the study were to assess the implementation of Co-Curricular Activitiesrn(CCA) in second cycle primary schools. To achieve the purposes descriptive survey method wasrnapplied. In the study, 4 sample groups encompassing 36 regular teachers, 114 students, 5rnprincipals and 3 personnel of Woreda Education Office (WEO) were participated. Questionnaires,rnchecklists and interview were instruments used to collect data. After data were collected, analysisrnwas made qualitatively and quantitatively. Hence, the results revealed that the majority ofrnparticipants had no clear awareness on the CCAs except Clubs. Moreover, the chi-square testrnemployed confirmed that Age, Grade level and Sex significantly affected the participation ofrnstudents in CCAs. Additionall y, it was found that the CCAs were not properly organized in thernschools. However, 14 types of clubs and 9 non-club activities were found in the schools (of thesernonly five clubs were commonly found in the schools).Regarding factors affecting thernimplementation of CCAs, the major problems identified were: Lack of budget and material, lowrnmotivation level of teachers, absence of facilities, absence of trained and skilled personnel atrnWEO and school level, lack of effective communication, low interest of students, extra-works ofrnstudents in home, absence of supportive material for teachers and work load of principals. Hence,rnthe findings showed that the implementation of CCAs was not undergoing in normal conditionrn(not good).Based on the findings, the following important lileasures were suggested: awarenessrncreation activities for the school communities, trainings for teachers and principals, use rewardrnsystem to motivate teachers, systematically organize CCAs to attract the interest of the students,rnestablish effective communication mechanism between implementers and higher educationrnofficial s, encourage using local reso urces or income generating scheme to reduce budgetrnconstraints. Furthermore, building net-work with Non-Governmental Organization (GOs) andrnCommunity Based Organization (CBOs) class ifying scientifically and limiting numbers of CCAsrnaccording to the need, Age, sex, developmental characteristics and feasibi lity of the schoolrnfacilities are very important measures should be considered to have effective CCAs. Lastly, inrnorder to create competitive atmosphere among i mp l em er: ~ers the establi slm1ent of effectiverncontinuous assessment and evaluation mechanism need to be sonsidered.
