Abstract: This study investigated the relationship between organisational climate and teachers� job performance in primary schools in Ondo State, Nigeria. As a descriptive survey was utilised, the study population embraced all the 1153 primary schools in the State. Out of this population; a sample of 360 schools was selected through stratified random sampling technique. The instrument used to collect data was a questionnaire on organisational climate and teachers� performance in schools. The data were analyzed using percentages, t-test, correlation analysis and multiple regression. The findings revealed that most of the schools run an open climate type of organisation. The level of organisational climate in the schools was however, very low. The level of the teachers� job performance was equally low. A significant relationship was however found between organisational climate and teachers� job performance. Based on the findings, it was suggested that headteachers should create a favourable climate to enhance better job performance among teachers. They should intensify more regular supervision of teachers and be more sensitive to their needs to enhance a conducive and enriching school climate. Government too, should provide all the necessary facilities and resources in schools.
