This paper examined conflict management strategies and administrative effectiveness in tertiary institutions in Sokoto metropolis. The study employed a correlational survey research design with questionnaire as the instrument of data collection. The population comprised all the eight tertiary institutions in the area. A sample of 168 lecturers were selected as respondents across four tertiary institutions. Two researcher developed instruments titled “Conflict Management Strategies Questionnaire” (CMSQ) and “Administrative Effectives Scale” (AES), with reliability indices of 0.82 and 0.85 respectively, were used for data collection. Data were analysed using Multiple Regression Analysis. The study established a significant relationship between dialogue, competition, prevention, and communication on one hand and administrative effectiveness on the other hand. It is recommended that tertiary institutions institutionalize dialogue as a conflict management strategy because through dialogue, team members develop skills to think together and to accept differences, thereby avoiding crises and improving performance.
