The study examined historical foundation of Western Education in the said region and the factors that influenced the development, the role of missionaries in relation to organization, management of schools, financial and physical support and the nature of mission-state partnership in the provision of education. This study identified schools using purposive sampling techniques basing itself on the categories of national, provincial and district schools. It also categorized them on the basis of church sponsors which were Catholic Church, Anglican Church of Kenya, Presbyterian Church of East Africa and Salvation Army. 18 (51%) schools were sampled from which, the BoG chairpersons (18), principals (18), and 3 teachers per school (54) were selected to fill in the questionnaires.
