Strategies with this rating are likely to work, but further research is needed to confirm effects. These strategies have been tested more than once and results trend positive overall.

Health Factors  

Cross-age youth peer mentoring programs establish an ongoing relationship between an older youth or young adult, usually a high school or college student, and a younger child or adolescent, usually an elementary or middle school student1. The more experienced mentor provides the less experienced mentee support, encouragement, and guidance for schoolwork and relationships with others. Mentors and mentees are often paired based on some shared characteristic or circumstance such as age, ability, or interests2. Cross-age youth peer mentoring programs are often organized by schools, community centers, or faith-based organizations; they can include one-on-one mentoring or group mentoring.

Evidence of Effectiveness

There is some evidence that cross-age youth peer mentoring programs increase social connectedness among elementary school-aged mentees3. Elementary and middle school students paired with high school or college student peer mentors appear to be better connected to their school, friends, and parents than classmates without mentors3. However, additional evidence is needed to confirm effects among mentees and mentors.

Participation in cross-age peer mentoring programs may increase mentees’ self-esteem, interpersonal skills, and peer acceptance3. Mentees may have greater involvement with, and a more positive attitude about, school than their classmates; mentees also report greater affection for their parents4. In some circumstances, cross-age peer mentoring programs can increase academic skills among mentees3 and decrease problem behavior among youth with the highest risk of engaging in delinquent behavior3, 5. Teachers report that elementary and middle school students mentored by high school students have better peer relationships than non-mentored students6.

An evaluation of a peer mentoring program for children with learning disabilities or attention-deficit hyperactivity disorder (ADHD), Eye to Eye, reports increased self-esteem and interpersonal relationships and decreased depression among elementary and middle school students, when paired with mentors with the same challenges7. It also indicates that mentees’ depression decreased to the level of peers without such difficulties7. Evaluations of a mentoring program that supports elementary school students who are bullied suggest that mentored children are less likely to be victimized than bullied children who do not have mentors8, 9. A UK-based study suggests that peer mentoring can be a good practice to provide emotional support and interpersonal benefits for female youth at risk of sexual exploitation, and to connect them with services10.

Cross-age peer mentoring may increase mentors’ connection to school, parents, and friends, as well as their self-esteem11. In some cases, mentors have shown improved interpersonal skills over the course of their mentoring relationship6, 12. College students who mentor middle and high school students also report more positive perceptions of community service and demonstrate greater problem solving skills than non-mentoring peers12.

Group-based cross-age peer mentoring can be incorporated in educational programs that promote healthy diets and physical activity among school children13, 14; use of trained high school peer mentors in school-based physical activity programs can be more effective at increasing physical activity and improving health outcomes in mentees compared to teacher-led programs14. Incorporating peer mentoring in youth peer support services appears to benefit youth with mental health challenges15. Ensuring adequate program coordination and leadership, choosing the right mentor, selecting the activities to facilitate the mentor-mentee relationship building, providing plentiful training and supervision to peer mentors, and allowing youths to lead the programs are recommended best practices in cross-age youth peer mentoring programs3.

Impact on Disparities

Implementation Examples

Programs such as Link Crew and IGNITE help freshmen transition into high school with the help of high school senior mentors in cities across the country16, 17. The Just Say YES peer-to-peer mentoring program in Dallas-Fort Worth pairs younger teens with outstanding high schoolers trained as mentors18, and San Jose’s Breakthrough Silicon Valley program matches middle school students who have high potential but lack opportunities with high school and college student mentors19. Girl Talk is an example of a program that connects female middle school students with female high school students20, and Denver’s YESS mentoring program matches high schooler seniors to freshman with similar cultural backgrounds21. Eye to Eye is a national mentoring program that connects middle school students with learning difficulties (e.g., dyslexia, attention-deficit hyperactivity disorder (ADHD)) with high school and college student mentors with similar learning difficulties22
