Currently, efforts to improve the quality of teachers in Cambodia are underway. To contribute infor-mation that can be used in the design of interventions, this study was conducted. Focus was on deter-mining the factors that influence teaching skills. Participants were 40 urban primary school teachers inCambodia. Data were gathered by questionnaire and classroom observations. Results of the correlationanalysis showed that teacher enthusiasm, teacher punctuality, pupil behavior, relation between theteacher and the pupils, the teacher's use of lesson plan, flashcards, supplementary exercises and visualmaterials were significantly positively related to the teaching skills.
