The evaluation of the IFNMG Campus Almenara portal was based on the recommendations of the federal government's Usability Primer. This study identified the main difficulties encountered by the institution's students with regard to the use and functionalities of the portal. Based on the guidelines discussed in the aforementioned booklet, it was possible, through an exploratory study of the site, to identify problems and possible difficulties encountered by students when accessing the portal. In order to ascertain these difficulties, a questionnaire was administered to clarify the students' perception of their familiarity with and access to technology. The evaluation of the portal against the information obtained was able to identify the difficulties experienced by IFNMG students in relation to the use and organisation of the site in terms of the concept of usability discussed in the booklet.
