This study investigated administrative strategies of departmental heads as determinants of effective management of human resources in tertiary institutions. Four research questions were asked and four hypotheses were formulated to guide the study. As a descriptive survey, the population comprised all the eight tertiary institutions in the state with 1898 academic staff and 4633 non-academic staff. A sample of 980 academic staff and 1550 non-academic staff was drawn through the multi-stage and stratified random sampling techniques. The instrument used was the questionnaire. Data collected were analyzed using Pearson correlation matrix, means and standard deviation, linear and multiple correlation and regression analysis. Results showed, among others, that there is significant correlation between administrative strategies and human resource management. It was recommended that departmental heads should equip themselves adequately with various administrative strategies.
