This study examines Hungarian pre-service and inservice teachers' satisfaction (n = 154) with the Mentored Innovation Model (MIM), an online collaborative mentoring model focused on technology integration. The Kano model was applied to results from two surveys to identify conditions in the MIM that most contribute to overall satisfaction with online mentoring. Self-efficacy with technology was identified as a must-be attribute. Online communication was a one-dimensional attribute contributing to linear increase of mentees' satisfaction, although preservice and inservice teachers' perceptions about the mentor's activity in the MIM differed. The results reinforce the importance of online communication during online collaborative mentoring.
