This report is a study caffied out in Baitambogwe Sub County, in Mayuge district which aimed at studying the relationship between teacher motivation and academic performance of pupils in Universal Primaiy Education (UPE) schools. Teacher motivation has been seen to be at its lowest in Baitambogwe Sub County, this stemming from a number of variables ranging from personal variables e.g. age, gender, marital status etc. situational I organizational variables, e.g. salary (pay), supervision, working conditions, company policy, recognition etc. These have greatly contributed to the demotivation of teachers and hence a dramatic fall in academic performance of pupils in UPE schools. Wafula (1991) also suggests that among the factors that demean the teaching profession in Africa countries are poor buildings in which teachers operate. Herman (1999) cited various factors that demotivates workers among which include low salaries, lack of fringe benefits, poor working conditions. Research findings have found out that the major demotivators cited by Herman are predominantly embraced in most UPE schools in Uganda not excluding those in Baitarnbogwe Sub County in Mayuge district. Research findings were established by use of several tools like self administered questionnaires, interview guides and interviews ofrespondents.
