The move from primary to secondary school is one of the biggest transitions a young person makes. A new campus, new teachers, a new timetable and an entirely new social world, all at once. For plenty of students it goes well. For others, the early months of Year 7 are where a sense of belonging quietly starts to slip, and where disengagement and attendance problems can take root long before anyone flags them.

Peer mentorship is one of the most practical, low-cost responses a secondary school has. Pairing older students with younger ones, or steadier peers with those still finding their feet, gives a student a familiar face, a reason to feel known, and someone to ask the small questions they would never take to a teacher. Done well, it builds connection at exactly the point where connection is most fragile.

This guide looks at what the evidence actually says about peer mentoring in schools, what separates programs that last from those that fade out by Term 2, and how to run one without turning a coordinator's week into a spreadsheet.

What the evidence says about peer mentoring

The strongest and most consistent finding is about belonging and connection, not marks. The Australian Student Wellbeing Framework puts positive, respectful relationships and a sense of belonging at the centre of both wellbeing and learning, and peer connection is one of the most direct ways a school can build them.

The Australian Education Research Organisation (AERO) has reviewed the evidence on wellbeing practices in schools and found that approaches which strengthen positive peer relationships can lift students' sense of belonging, connectedness and engagement. Its guidance on belonging and connectedness points the same way: students who feel they belong take part more, and are far more willing to ask for help when they need it.

It is worth being honest about the limits. The same reviews are cautious about academic gains: the evidence that mentoring lifts achievement directly is mixed. Peer mentoring is best understood as a belonging and wellbeing strategy that supports the conditions for learning, not a shortcut to higher results. The reviews are clearer about what makes mentoring effective. It works best when contact is regular (at least weekly), when the program runs long enough to build a genuine relationship (ideally across a year rather than a few weeks), and when it mixes social connection with structured, goal-focused activities.

What makes a peer mentorship program work

The programs that survive past the launch tend to share the same features:

  • Deliberate matching — pairs are chosen with some logic (year level, house, staff knowledge of the students), not left to chance.
  • A clear structure — mentors know what they are actually meant to do, with concrete activities rather than a vague brief to "check in".
  • Regular, protected time — mentoring that relies on students bumping into each other at lunch quietly dies. Lasting programs give it a scheduled rhythm.
  • Recognition — mentoring is real work. When students are acknowledged for it, they take it seriously and keep turning up.
  • Staff oversight and safeguarding — a named coordinator, clear boundaries, and an obvious way for a mentor to raise anything that worries them.

Why programs fizzle out

The failure pattern is almost always the same. A program launches with real enthusiasm at the start of the year, pairs are formed, and then nothing structures the weeks that follow. Mentors are unsure what to do, meetings stop happening, and by Term 2 the program exists on paper only. The fix is rarely more enthusiasm; it is structure. Defined activities, a predictable rhythm, and visible recognition are what keep momentum alive once the novelty wears off.

How AchievoEDU supports peer mentorship

AchievoEDU includes a buddy program built around exactly these lessons, so a coordinator can run mentoring without managing it by spreadsheet.

Matching. The platform can automatically match mentors and mentees, with an option to prioritise pairing within the same house so mentoring reinforces house identity. Each mentor takes on up to two mentees, so no student is over-committed, and staff can review, adjust or reassign any pairing.

Structured challenges. Rather than leaving mentors to guess, the program runs on shared challenges, each with a clear purpose and worth a set amount of XP. The defaults include practical, relationship-building tasks such as a School Tour Guide activity, a Goal Setting Session, a Skill Share, a House Pride Event and an open Wellbeing Check-In conversation. Schools can edit, add, reorder or remove challenges to suit their own program.

Momentum that looks after itself. Two challenges complete automatically from activity the platform already tracks: a Check-In Champion streak for four weekly check-ins in a row, and a House Points Push when both partners earn 100 or more house points in a single week. That keeps pairs active without a coordinator chasing paperwork.

Because challenges are grouped into connection, growth, house and wellbeing themes, a coordinator can see at a glance whether pairs are genuinely engaging, and step in early where they are not.

Getting started

You do not need a platform to begin. A strong pilot can start with a dozen carefully matched pairs, a weekly time slot, and three or four defined activities for the term. What matters most is structure and follow-through, not scale. When you are ready to extend mentoring across year levels without the admin load, a tool like AchievoEDU's buddy program can carry the matching, the activities and the recognition for you.

Peer mentorship will not fix everything a secondary school faces. But few things do as much, for as little, to help a young person feel they belong. For more on why connection matters, see our piece on school belonging and student outcomes, or book a demo to see the buddy program in action.
