The population of the study consists of 5,246 teachers of public secondary schools in the study area while the sampling size which was randomly chosen comprised 1,246 teachers. The instrument for the study was a 10 item structured questionnaire that consisted of two clusters. Cluster A dealt with the extent of the application of management matrix by principals of schools while cluster B was concerned with the factors that affect the application of management matrix in public secondary schools in the study area. The instrument was validated by three experts, two from the Department of Educational Management and Policy one from the Department of Education Foundations. All in the Faculty of Education. The reliability of the instrument was obtained through Cronback Alpha with cluster A weighing 0.76 and cluster B weighing 0.84, all having a weighted average of 0.80 which was considered high enough for the study. Mean and standard deviation were used to answer the research questions while the hypotheses were tested at 0.05 level of significance. The null hypotheses were rejected when the calculated p-value was less than 0.05 level of significance while it was accepted when the calculated p-value was higher than the 0.05 level of significance. The finding of the study showed among others that most principals are ignorant of the application of management matrix, as such their managerial effectiveness is not enhanced.
