The modern era is marked by a rapid flow of information, which carries ever greater progress in all spheres (aspects) of life, especially in terms of technological achievements. This implies a constant need for new information, but also a continuous insight in the same. This thesis shows the elaboration and implementation of the “eNastavnik” application, i.e. the application that is offered as one of the solutions to the mentioned, new demands of the society. Namely, the “eNastavnik” application has been developed as a web solution that makes the job of a teacher easier by replacing a "manual" way of keeping track of success and providing the possibility to create quizzes that have a feature to check the learnt content. In this context, i.e. in order to maintain a certain contemporary standard, modern software technologies have been used in creating this application. The main programming languages used for creating are: C # and JavaScript with their framework additions, while the application itself uses the SQL database to store the data.The application logic is done in two parts: Backend and Frontend. In other words, this thesis describes the creation and representation of the application that provides a continuous insight into the progress of each student in terms of accessing the application through assigned / divided three roles: "student", "parent" and "teacher". Each of the roles has different access to certain data, most of which is attributed to the "teacher" role that has administrator permission in the system.
