The researchers explored the benefits, challenges and preferred methods of communication of those who took part in the "¡Guiamos!" online and face-to-face mentoring program. Participants included 21 novice pre-service teachers who served as mentees and 32 experienced educators of English language learners who served as mentors. To explore the answers to the research questions, participants completed a survey which contained Likert-scale items and open-ended questions. The researchers found that "¡Guiamos!" mentors and mentees rated a large number of benefits highly ranging from the improvement of relationships to increases in knowledge and skills; and in their commitment to teaching. Furthermore, with the exception of not having enough time, participants perceived challenges within the mentoring program as occurring relatively infrequently. In regards to mentor-mentee communication preferences, participants favored email and least favored video-conferencing.
