The findings established that each of the factors, had good internal reliability values 0.88%, 0.87%, 0.87%, and 0.81% respectively. The SEM model of school motivation confirmed that the factor structure was a good model as the RMSEA (p = 0.066) was significant at a high level. Further, it was also affirmed that inter-correlations existed among each of the components: cognitive and success motivation (r = 0.95); cognitive and social motivation (r = 0.73); and success and social motivation (r = 0.73). Low correlation existed between the components of social and failure avoidance motivation (r = 0.03).
