The study established the influence of parenting style on involvement in education of public preschool learner, in Nandi Central Sub-County, Kenya. The study adopted the Concurrent Triangulation design within the mixed methods approach. The target population was 3566 which was composed of 183 head teachers’ public primary school, 183 lead teachers of public Early Childhood Development Education and 3200 parents of top class in Nandi Central Sub-County, Kenya.
