Due to the Covid-19 pandemic, distance education has been enhanced through the use of Information and CommunicationTechnologies (ICT) at all levels. That is why several institutions adopt different approaches to distance education. Given the above, a comparative study of face-to-face and synchronous academic performance is carried out between Santiago de Cali University and Universidad Libre de Cali, where a survey was conducted with 300 students from both universities. The Saaty's Analytic Hierarchy Process (AHP) multicriteria analysis method was used to analyze how difficult it was for students to achieve their learning objectives and maintain the quality of distance classes. The obtained results showed that throughout all the classes, many students encountered numerous issues such as connection problems or power failures. It is also noticeable that there has been an increase in individual work by students and a lack of class participation. However, despite these situations, students have a perception of acceptable achievement regarding their learning objectives and their experiential experience with teaching practice in fulfilling their teaching objectives in ICT-mediated classes
