Metodología

Active and participatory course through demonstrations, practical exercises and clinical analysis of users of all the theoretical topics taught by the instructor in order to deal with real cases of the related product. The trainer will also use different dynamics that allow group work in the classroom as challenges, evaluation exams and real cases to prepare for the associated Linux Foundation certification exam, if there is one.


Certificaciones

Continual evaluation based on group and individual activities. The faculty will give continuous feedback and at the end of the activities to each participant.

During the course the participants will complete an evaluation test that must be passed with more than 75%. They will have one hour available for its realization.


Acreditación
