This article deals with the design and implementation of a new web application for the evaluation of lessons and teachers by students. This application is accessible from a smartphone or any other computer device to allow the student to evaluate. The latter has access to the application once registered, hence his number and first name gives him access. Finally, the application produces a summary evaluation report for a teacher per course and annually for all the courses given by a teacher according to the criteria defined in the Vadmecum for managers of a higher education and university establishment. It is designed in client-server architecture with PHP programming language which is mainly used to produce dynamic web pages through a HTTP-server, but can also function as any interpreted language locally with a database that runs on the MySql server allowing the exploitation and manipulation of stored data. The man-machine interface offers the user a user-friendly form containing clear and explicit criteria and validation button and also a button allowing the student to check all his courses already evaluated.
