Parental participation is a key ingredient for education intervention and socio-economic development. Education access, retention and participation are achieved through emphasis on inclusive education in regular schools for learners with special needs and disabilities, and parental participation through financing. In Kenya the financing of SNE is the constitutional obligation of both the government and the parents. The occurrence of low accessibility to SNE in spite of increased government financing to the programmes has been linked to various factors. The purpose of the study was to determine the selected factors influencing parental participation in financing SNE programmes in public primary schools in Mombasa County, Kenya. The study was guided by the following objectives: To determine parental participation on access to SNE programmes in public primary schools in Mombasa County; to establish parental participation in decision making in financing SNE programmes in public primary schools in Mombasa County, and to determine the parents' ability to finance SNE programmes in public primary schools in Mombasa County.
