There is a sound research base attesting to the importance of parental involvement and to the many potential benefits it can offer for children's education. This study sought to examine differences in parental aspirations (as a mechanism of parental involvement in their children's education) for their children's educational attainment between slum and non-slum residing parents in Kenya. The study used cross-sectional household data for a sample of 4065 parents, collected in 2007 by the African Population and Health Research Centre (APHRC) in Nairobi. A multinomial logistic model was used for the analysis to explore the factors determining parental aspirations. The results indicate the following: (i) that parents who live in the slums have lower aspirations for their children's educational attainment when compared to those who live in non-slum areas; (ii) that parents in the slums have aspirations for higher levels of educational attainment for their children than their own levels of education. We conclude that parents in urban Kenya have a strong belief in the education of their children irrespective of their slum or non-slum residence but aspirations are higher in non-slums than in slums.
