摘要：In this work, we have developed a web application for Baccalaureate grades processing in Niger. This online application allows to replace Excel based manual grades processing with fully automated one. Thus, the application helps to minimize the errors caused by the Excel manipulation. It also allows rapid centralization of all results at the exam service level. For the development, we adopted the agile method. This method is very efficient in allowing us to prioritize our real needs and the application is enriched as these needs arise. For the design, we used the UML Modeling language and for the implementation, we used a number of computer tools such as PHP, JavaScript, HTML, Jquery, AJAX, Bootstrap and CSS.
