This thesis aimed at investigating Budget Management as a Tool to Effective Secondary Technical Schools Administration in the South West Region of Cameroon. The researcher used these variables: budget planning, budget preparation, budget execution and budget evaluation. Data were collected from primary sources through administration of questionnaire using a four point Likert scale format. This instrument was administered to sixty-two (62) principals, fifty-nine (59) bursars and five interview guides questionnaire items to sixty three (63) teachers randomly sampled from sixty five (65) secondary technical schools in the South West Region of Cameroon. Secondary data were collected from journals and magazines from all quarters. Chi-Square test of data analysis was used to analyze the extent and impact of these variables on effective secondary technical school’s administration in the South West Region of Cameroon. The findings obtained revealed that: Budget planning does not have any significant impact on effective secondary technical school’s administration with P>0.05. Budget preparation had strong positive significant impact on effective secondary technical school’s administration with P<0.05. Budget execution had strong positive significant effects on effective secondary technical schools administration with P<0.05. And budget evaluation had moderate positive significant effects on effective secondary technical school’s administration with P<0.05. It was concluded that budget management have positive significant effects on secondary technical school’s administration in the South West Region of Cameroon. It was recommended among other things that budget committees should be created to involve stakeholders in budget planning and to regularly audit and evaluates the challenges faced in budget management. Expenditures limit should be set when preparing the school budget to enhance addressing operational efficiencies in technical schools. Departments in technical schools should be encouraged to often submit their draft budget to hierarchy so that allocation of resources in budget execution can be made equitably toward staff needs for better teaching and learning.
