Today 98% of students have access to a bouquet of digital services through their cyberspace. Pending of settlement and maintenance costs, the question arises to measure the usefulness of the panoply of services deployed. If this is straightforward locally for a bunch of services, the same question independently of the technology would offer more details on student’s behaviour. From the point of view of an entity providing digital services, at the level of governance or policy makers they may also need other indicators such as the number of services offered and their respective rates of use. We show how to avoid most technical issues, and we deal hereafter with determining the good levels of usage. The Agimus system, an open and free application is used to generate a bundle of indicators. Agimus is based on normative repositories of description of user profiles. We'll show how the device paves the way in a quality approach for improvement of the digital services provided by one or more organizations, the co-construction of knowledge, among others, on the statistical behaviour of the client users. Examples of indicators implemented will be taken on institutions of higher education digital services.
