This study investigated the extent to which management of educational facilities relates to quality education delivery in public senior secondary school in Rivers State. Four research questions and four corresponding hypotheses were used to guide the study. This study adopted correlational research design. The population for the study consists of 522, principals and vice-principals that is, 261 principals and 261 vice-principals in the 261 public senior secondary schools in Rivers State. A sample of 200 principals and vice-principals were drawn through simple random sampling technique and used for the study. Two instruments titled ‘‘Education Facilities Scale’’ (EFC) and ‘‘Quality Education Delivery Scale’’ (QEDS) were used for data collection. The instruments were validated by three experts; one in measurement and evaluation and, two others in Educational Management based on face and content validities. The reliability coefficients of the instruments were determined using Cronbach Alpha Method and the reliability coefficient obtained were 0.71 for (EDC) and 0.81 for (QEDS) respectively. The researchers personally administered the instruments to the respondents with the help of research assistants (Head Teacher) in each sampled school, who were properly instructed on what to do. The instruments were retrieved immediately after administration.
