Two hundred pupils male and female of age 12 and 14.5years from both public and private primary schools in Nairobi city participated in the study. Multiple regression and t-test were used for data analysis. The results revealed that three independent variables; intelligence, achievement, motivation and type of school jointly and significantly contributed to the prediction of academic achievement of the urban primary school pupils. (R = 0.693, P < .01). In terms of magnitude of contribution, intelligence turned out to be the most significant predictor (Beta = .445, t = 7.503, P< .01) followed by achievement motivation (beta = 0.282, t – 5.042, P< .01) and type of school (Beta = 0.208, t = 3.615, P < .01). The results of t – test revealed that students from private schools differ significantly from students of public schools in academic achievement and intelligence but not in terms of achievement motivation.enBook chapter
