This study focused on the extent to which managerial characteristics moderate the relationship between strategic planning process and institutional performance. Descriptive survey design was adopted. Both stratified and purposive techniques were used to collect data from twenty-six accredited private universities with strategic planning committees. The extent of effect of strategic planning on performance was determined with linear regression. In addition, the determination of any significant moderating interaction between the identified decision maker characteristics and strategic planning process over performance was achieved by means of a Binary Logistic Regression analysis. Findings have been presented, and recommendation made.
