Benefits attributed to classical mentoring (when an older adult mentors a younger person) can translate to peer mentoring relationships, mainly when the peer mentor and the mentee have similar backgrounds. Some colleges and university campuses have encouraged peer mentorship programs to aid retention of under-represented populations, such as women in economics. The lack of role models or volunteers forces administrators and student leaders to use students as peer mentors of other students—usually first year students, ethnic minorities,[19] and women[20]—in order to guide, support, and instruct junior students; Because peer mentoring programs require a low budget for administration and/or development, they become a cheap alternative to support students perceived as likely to fail.
