The target population involved 163 public secondary schools, 978 student leaders, 4694 teachers, 163 heads of schools, seven DCSQAOs, and seven DSEOs. Probability and non-probability sampling procedures were employed to determine the study sample of 16 schools, 16 heads of schools, 469 teachers, 98 student leaders, six quality assurance officers and six DEOs, making a total of 595 respondents. The instruments used to collect data were questionnaires, interview guides, focus group discussion guides and document analysis guides. The quantitative data were analyzed descriptively and inferentially in frequencies, percentages, means, and presented in tables and interpreted in relation to research questions. The qualitative data were analyzed by coding contents into themes, interpreting direct quotations and presented in narrative form. The findings revealed that in most schools there was moderate level of involvement of educational stakeholders in preparation of strategic plans.
