The research study focuses the effects of mandated-training for protégés on mentor outcomes within a large-scale e-mentoring program MentorNet for adults. In this randomized experiment, 200 protégés were assigned to a mandated e-training (experimental) group, and another 200 protégés were assigned to a voluntary e-training (control) group. The mentors were more satisfied, engaged with program, and held their protégés in higher esteem.
