Background: Poor hygiene practices and conditions create a serious public health threat to school children. This evaluation aimed to assess School Water sanitation and Hygiene (SWASH) project established for providing better school environment to the school children and better hygiene conditions to all pupils. The specific objectives included assessing the alignment of the project to the national guidelines, hygiene practices behavior of the pupils as well as the perception of implementers of this program. Methodology: The study was qualitative and a descriptive cross sectional study design where a formative evaluation approach was employed. A sample size of 8 primary schools with 80 people was used in the study. One on one interviews, Focus group discussion and observations checklist were used to extract data from the study participants. Data was analyzed through content analysis technique with the help of Atlas ti software, where codes, themes and quotes were created Results: The overall results showed that none of the 8 schools had met the standards of school WASH. 2 district implementers and 16 school teachers were interviewed while 62 pupils (56%) females and (43%) males were in a focus group discussion. The majority of Pupils seem to have fair knowledge on hygiene related diseases but poor practice on hygiene practices. 85% of interviewed pupils never wash their hands after toilet use and 83.87% of them do not like their school toilets despite of them using it. The implementation process is a big challenge to the implementers of both sides (district and schools). Conclusion: The evaluated primary schools have poor hygiene conditions mainly due to poor planning and implementation of the programme. The school children practices poor hygiene behavior due to lack of knowledge and means made available for them to practice safe hygiene practices. Lack of water and sanitation facilities is stated as the main obstacle for the pupils to practice safe hygiene behavior. The implementers find that the biggest challenge in the implementation of School WASH is poor or too little budget for the project and poor commitment of the government in running school WASH. Poor partnership and co- ordination between the department of education and health are also observed as the driving challenges to the implementation of school WASH. Efforts should be made by the government in improving these challenges.
