Abstract
This Study Showed How Efficiency And Security Can Be Enhanced In The Management Of Examination Result Of Students In The School Of Computer Studies The Researchers Went To The Case Study And Used Interview, Observation And Dissemination Of Questionnaires, To Collect Data At The School With A Bias Towards The Examination Office. This Data Was Then Analyzed And A Using Software Development Life Cycle (Sdlc) Developed A Secured Network Application. (Secured Online Examination Result Management System)
