Group Mentoring: How to Run a Program That Works

Last Updated: 9 November 2026

While traditional mentorship typically involves a one-on-one relationship between a mentor and a mentee, group mentorship takes a different approach. Group mentorship brings together a small group of individuals who share common goals, interests, or experiences. Instead of relying solely on one mentor, group mentorship leverages the collective wisdom and diverse perspectives of the entire group. 

Group mentoring puts one or more mentors with several mentees, or a set of peers, in regular shared sessions. Research on youth programs finds it about as effective as one-to-one mentoring, and it can cost less per participant. It works best with small groups, a clear purpose, a facilitator and tracked participation.

What is Group Mentoring?

Group mentoring is a structured program where one or more mentors meet with several mentees together, or where peers mentor each other in a consistent group. Unlike a one-off workshop, the same people meet repeatedly, and the conversation runs in both directions. Most programs use a one-to-many, peer or cohort format.

The common formats differ mainly in who leads and how many people take part:

• One-to-many: one mentor with a small group of mentees. Published youth mentoring models use about 3 to 10 mentees per mentor, and most programs settle at 4 to 6 (National Mentoring Resource Center).
• Multi-mentor: two or three mentors with a larger group, about 5 to 20 mentees in the same models.
• Peer groups: no designated senior mentor. Participants share experience with each other, often around a common role or challenge. See peer mentoring.
• Cohorts and communities: groups formed around a shared stage or identity, such as a graduate intake or an employee resource group.

Group Mentoring vs One-to-One Mentoring

Group mentoring spreads one mentor's time across several people and builds peer networks. One-to-one mentoring offers more privacy and advice tailored to one person. A meta-analysis of youth programs found no difference in effectiveness between the two formats, so the right choice depends on your goals, mentor availability and how personal the topics are.

The formats are not mutually exclusive. Brancher's platform runs one-to-one, group and peer programs side by side, so you can use each where it fits. Brancher's group mentoring page covers the group setup.

Benefits of Group Mentoring

Group mentoring lets one mentor reach several mentees at once, and the research suggests it works about as well as one-to-one mentoring in youth programs. A meta-analysis found no difference between the formats, and a workplace survey found 93% of participants rated the topics relevant to their jobs.

• Relevance and application: In a survey of group mentoring participants, 93% said the topics were relevant to them and their jobs, and 96% said they could apply what they learned directly in their role (Emelo, 2011).
• Evidence of effect: Of 29 youth group mentoring programs with comparison-group studies, 24 reported significant positive effects on at least one outcome (National Mentoring Resource Center).
• Cost: A national survey of US youth programs reported about US$1,191 per participant for group programs against US$1,913 for one-to-one programs.
• Peer connection: A randomised trial found pairs embedded in groups made similar gains and reported more social connections (Haddock et al., 2020, as summarised by the National Mentoring Resource Center).

Three limits apply to this evidence. The strongest studies involve US youth programs, not workplaces. The Emelo survey is from 2011, the report does not state its sample size, and its author led a mentoring software company. Some group programs also showed small negative effects, and large groups can weaken cohesion. We found no Australian group mentoring outcome data in this review.

How to Run a Group Mentoring Session

Run each session with a clear topic, a facilitator and a fixed structure: a short check-in, a focused discussion, and agreed actions before the next meeting. Keep the group small enough for everyone to speak and meet on a regular schedule. Published group programs commonly meet weekly or fortnightly.

A simple 60-minute structure (suggested format, not drawn from research):

1. Before the session: Send the topic and one guiding question so people arrive prepared.
2. Check-in (10 minutes): Each person shares progress on the last action.
3. Core discussion (35 minutes): The facilitator runs a case, a question round or a short activity, and makes sure everyone contributes.
4. Close (15 minutes): Each person states one action for next time, and the facilitator records them.

For the first session, agree ground rules on confidentiality, respect and feedback, and use an icebreaker. Our guide to inclusion in group mentoring covers this in detail.

Plan for the group to take time to settle. Tuckman's group development model (forming, storming, norming, performing, adjourning) informs at least one published group program. Practitioners cited by the National Mentoring Resource Center regard fewer than four or five meetings as too few to build relationships.

Group Mentoring in the Workplace

In the workplace, group mentoring suits onboarding cohorts, leadership development, employee resource groups and peer learning. It works well for topics many people share and for mentors with limited time. In a research, 18% of organisations offered group mentoring, which suggests many programs could add it.

Brancher supports these uses:

• Onboarding: Help new starters and graduates build connections early. See onboarding new staff and graduates.
• Leadership pipelines: Group sessions for emerging leaders. See developing high potentials.
• Inclusion: Employee resource groups and cross-cultural groups. See employee resource group activities.

A Brancher program at scale. Women in Media started with a state-based pilot and grew it into a national program across five or more cohorts. Brancher reports 183 matched pairs, 100% match satisfaction in the national cohort and 92% retention. This was a one-to-one program run in cohorts, not a group mentoring program. Read the Women in Media case study.

Group Mentoring Best Practices

Effective group mentoring programs set a clear purpose, keep groups small, agree ground rules, appoint a facilitator and track participation from the start. Large groups weaken cohesion and can form cliques, and a curriculum followed too rigidly can hinder relationships, so leave room for conversation.

1. Define the purpose before recruiting. Unclear goals are one of the common causes of program failure. See why mentoring programs fail.
2. Keep groups small. Start at the 4 to 6 range most published programs settle on, then adjust after a pilot.
3. Set ground rules in session one. Cover confidentiality, honesty, respect and how feedback is given.
4. Appoint a facilitator. This is usually the mentor, who keeps time and invites quieter members in.
5. Watch for power imbalances. Seniority, gender and background can shape who speaks. Intervene early if one voice dominates.
6. Form groups on compatibility, not only job title. Brancher's matching considers personality and values as well as goals.
7. Track attendance and relationship health during the program. Retention varies widely. One youth program kept fewer than half its participants over a year, and another saw completion rates from 30% to 100% across sites (National Mentoring Resource Center).
8. Mark milestones. Recognise progress at the midpoint and at close to sustain attendance.

Best Platforms for Group Mentoring Programs

The best platform for a group mentoring program supports your group format (one-to-many, peer or cohort), forms groups without heavy admin, and reports participation by group. Brancher, Mentorloop, Qooper, Together and 10KC all list group formats. They differ in how groups are formed and how much group detail they publish.

Disclosure: Brancher publishes this guide and is listed in the table. Details below come from each vendor's own pages, checked on 9 November 2026, and may change. Check them against current vendor information before you buy.

Questions to ask any vendor (suggested checklist):

1. Which group formats do you support, and do any require a higher plan?
2. Are groups formed manually, by self-selection or by an algorithm?
3. Can a participant belong to more than one group, and can I switch that off?
4. What does the admin see for each group: attendance, engagement, goal progress?
5. Can I export group data for stakeholders?

What Brancher Offers for Group Programs

• Matching built on personality and values. The Strengths & Values Analyser assesses personality, motivators and values before groups form. Brancher says its group page can form groups "in seconds, rather than days."
• Goals Module. Participants log a backlog of goals, mark those in progress and complete them, and admins see progress live without a separate check-in.
• Real-time dashboards. Engagement, progress and outcomes update as the program runs. Standard dashboards and reports are on the Core plan, and advanced, customisable reporting is on Enterprise.
• Automated check-ins and reminders. Scheduling, calendar syncing and reminders run without admin chasing. SSO and integrations with Google, Outlook and Teams are supported.
• Ava AI. Ava AI gives participants prompts and guidance between sessions.
• In development. Brancher is working on insights that may suggest next actions, such as flagging participants who have not met recently, plus engagement trends over time and reporting segmented by division or location. No release dates are committed.

Pricing is tiered, and the cost per user falls as team size grows. Brancher provides quotes on request. Read more in progress tracking in mentoring software, or book a demo.

Frequently asked questions

What are the best platforms for group mentoring programs?

The best platform for a group mentoring program supports your group format (one-to-many, peer or cohort), forms groups without heavy admin, and reports participation by group. Brancher, Mentorloop, Qooper, Together and 10KC all list group formats. They differ in how groups are formed and how much group detail they publish.

How many people should be in a mentoring group?

Published group mentoring models use about 3 to 10 mentees per mentor, and most programs settle at 4 to 6. These figures come from youth mentoring programs, so test group size in a pilot for workplace settings.

Is group mentoring as effective as one-to-one mentoring?

In youth programs, a meta-analysis found no difference between group and one-to-one formats overall (DuBois et al., 2011). Results may depend on group size, facilitation and attendance. Evidence from workplace programs is thinner.

How often should a group mentoring session run?

Published programs commonly meet weekly or fortnightly. Fewer than four or five meetings is generally considered too few to build relationships, so plan a program length that allows at least that many.

How do you measure a group mentoring program?

Track attendance, participant feedback and progress against agreed goals for each group, and review them during the program rather than only at the end. Brancher's dashboards report engagement and progress as the program runs.
