These working tags describe the approach’s focus. Conditional connections depend on the particular barrier, goal and application. Professional delivery roles remain recorded separately.

Direct focus

• 03 Communication & connection — Peers are prepared to change reciprocal communication, group entry and shared interaction.
• 06 Agency, safety & participation — The intervention explicitly changes peer-controlled access and participation conditions around the young person’s chosen goals.

Conditional connections

• 04 Learning & making meaning — Relevant when a specified peer-support programme targets academic learning and peers are trained for that purpose.

• E098 Difficulty joining shared activities or groups — Read alongside this approach when peers can help make shared activity more accessible and reciprocal. Keep the young person’s choice to join, remain or leave visible.
• E016 Peer-relationship difficulties — Read alongside this approach when peer access, responsiveness or opportunities for shared activity form part of the difficulty. Participation, friendship and belonging require distinct evidence and should not be inferred from one another.
• E066 Difficulty keeping track of group conversations — Read alongside this approach when conversational timing or partner responses affect participation. Peers may learn to wait and respond, but the young person should retain their own communication style and right not to take a turn.

What belongs to this approach

Peer-mediated approaches deliberately prepare and support peers to change an interaction, learning or participation environment. Peers may learn how to initiate accessibly, notice and respond to communication, use augmentative and alternative communication (AAC), invite participation, share an activity, provide academic support, repair misunderstanding or alter group routines. Adults design, coach, safeguard and gradually reduce unnecessary support.

The mediator is a peer, but the intervention remains an adult responsibility. A classmate is not a therapist, unpaid carer, interpreter, behaviour manager or safety plan. Participation must be voluntary, developmentally appropriate and supported for everyone involved.

A022 is not:

• assigning a “buddy” without goals, training, choice or review;
• manufacturing or requiring friendship;
• placing a young person near peers and counting proximity as inclusion;
• a generic cooperative-learning task or peer-tutoring arrangement unless peer actions are deliberately taught to address an identified access goal;
• a social-skills group that seeks change only in the focal young person;
• A017 Communication partner strategies, which applies to any communication partner and need not recruit peers through a defined intervention;
• a substitute for A018 AAC, environmental access, adequate staffing, teaching, safeguarding or specialist assessment.

The evidence boundary is a specified peer-mediated programme or procedure: who participates, what peers and adults do, where it occurs, how support is taught and faded, and which outcomes are measured. Named models such as peer networks, peer support arrangements, integrated play groups or peer-mediated social interventions have distinct protocols and should not be treated as interchangeable.

Named programme and format routes

LEGO-based collaborative work can involve a defined programme rather than a general brick club. The I-SOCIALISE school trial protocol, investigating social competence and isolation through LEGO-based group work, describes rotating engineer, supplier and builder roles followed by collaborative free building. Its trial programme is also described as Play Brick Therapy in the later implementation paper. Record the manual/version, adult preparation, peer roles and communication support; do not assume that a local four-role group or ordinary construction activity is the same programme. These sources establish the programme identity and delivery questions, not a new A022-wide effectiveness claim. (I-SOCIALISE protocol; implementation study)

Circle of Friends can describe a facilitated peer-support format. The author-described process includes a volunteer peer group, an adult-facilitated problem-solving meeting with the focal young person, and continuing review. A school project using the name does not establish which model or procedures were used. Specify peer preparation, meeting arrangements, goals and adult responsibilities before identifying a named A022 profile. This process description is not evidence that a particular local group improves friendship. (Author process account)

For either route, retain A022's existing protections: explain whether each participant is receiving support, helping facilitate it or both; invite rather than compel participation; agree what information may be shared; check continuing willing participation; and offer a usable way to decline, pause or withdraw. Review the experience and burden of every participant. Adults retain safeguarding and support responsibilities; successful building, attendance or a group name cannot stand in for reciprocal participation or friendship.

Purpose and evidence boundary

Teaching one young person to behave more conventionally does not by itself address the surrounding group’s opportunities and barriers to participation. Peers control invitations, conversational pace, group entry, shared interests, status and many informal opportunities. Preparing peers and organising meaningful shared activity changes opportunities that adult instruction alone may leave untouched.

Systematic reviews and controlled studies report encouraging effects on social interaction, communication, network salience, teacher-rated skills and reduced isolation in some school-based programmes. However, samples and measures vary, follow-up is limited, and adult-counted initiations or time near peers do not prove friendship, belonging or a positive experience. A 2023 friendship review found a favourable within-group pooled effect but no statistically clear between-group advantage, and friendship quality did not clearly improve.

A022 therefore asks: What peer-controlled barrier or opportunity is being addressed, what will peers and adults learn to do, does the young person want this support, and does it improve reciprocal and meaningful participation without creating burden, hierarchy or coerced friendship?

Core components

Begin with the young person’s goal and willing participation

Find out where, with whom and how the young person wants greater access. The goal may be joining a game, contributing to group work, communicating through AAC, sitting with others at lunch, taking part in a club or developing a chosen acquaintance. Respect a preference for solitude, one-to-one interaction or no intervention. Review willing participation throughout, not only at referral.

Understand the group and its environment

Observe routines, group rules, noise, pace, physical access, adult positioning, peer networks, shared interests, communication demands and points at which participation opens or closes. Identify what peers genuinely control and what adults or systems must change. Do not formulate exclusion solely as a deficit in the focal pupil.

Select peers transparently and voluntarily

Use an ethical recruitment process appropriate to age and setting. Consider shared interests, natural contact, reliability and diversity rather than selecting only high-status or highly compliant classmates. Explain the activity without unnecessary disclosure. Obtain agreement, permit withdrawal and avoid dependency on one “special helper”.

Teach a small set of usable peer actions

Define observable actions matched to the goal: invite and wait; offer a clear role; use the person’s communication mode; respond to attempts; share materials; model a task; provide a choice; repair; check rather than assume; or make space in a group. Combine explanation, modelling, rehearsal, guided practice and feedback.

Structure meaningful shared activity

Use ordinary, age-respectful activities with a genuine shared purpose or interest. Adapt materials, roles, group size, communication supports and timing so all participants can contribute. The interaction should not exist solely so peers can “practise on” the focal young person.

Coach in context and fade carefully

Adults establish safety, prompt discreetly, reinforce reciprocal participation, solve barriers and monitor burden. Fade intrusive prompting and proximity when interaction becomes workable, while retaining the environmental arrangements that make access possible. Fading should not mean withdrawal of needed communication or safety support.

Protect reciprocity and status

Ensure the focal young person can initiate, refuse, help, lead, change the topic and offer expertise—not only receive help. Rotate roles and peers where appropriate. Avoid praise systems that publicly mark one person as the object of kindness or position another as morally superior.

Plan for generalisation without claiming friendship

Practise across relevant activities and partners, using natural cues and interests. Generalisation may involve more independent participation or a broader network. Friendship remains voluntary, personal and mutual; it cannot be prescribed as an intervention outcome without direct evidence from the people involved.

Monitor everyone’s experience and the actual outcome

Record implementation, reciprocal interaction, communication, participation, independence, social validity, peer burden, adverse experiences and maintenance. Ask the focal young person and peers whether the arrangement feels useful, natural, safe and wanted. Adult observation alone is insufficient.

What this may look like

Peer-mediated approaches may include:

• classmates learning how a peer communicates and how to wait for a response;
• a small voluntary peer network meeting around shared interests and ordinary school activities;
• peers inviting a young person into a chosen playground game using an agreed cue;
• cooperative group roles adapted so every member has meaningful control and contribution;
• a peer learning to model or respond through the young person’s AAC without touching or speaking through the device;
• peers sharing a visual task plan or checking one instruction at a time during practical work;
• a lunchtime club organised around a strong common interest rather than generic conversation practice;
• peers learning how to pause, clarify and repair a misunderstanding;
• a rotating group rather than permanent dependence on one buddy;
• adult coaching before and briefly during a natural activity, followed by debrief;
• opportunities for the focal young person to teach, lead or support peers;
• explicit permission for any participant to decline, pause or change the arrangement;
• measures of shared turns, reciprocal communication, contribution and chosen participation;
• direct checks of belonging or friendship where those are the claimed outcomes;
• review of whether interaction continues when adult prompts reduce.

Peer mediation does not require extroversion. A successful outcome may be reliable access to a group task, one authentic exchange, a comfortable shared activity or the ability to decline without social penalty.

Tiered use

Tier 1 — Universal peer culture and access

Teach all pupils accessible group routines, respect for different communication modes, repair, consent, anti-bullying expectations and multiple ways to participate. Design clubs, classrooms and unstructured times so entry does not depend on fast social inference. Universal culture supports but does not replace an individual peer-mediated plan.

Tier 2 — Targeted peer group or network

Prepare a voluntary small group for a recurring activity, shared interest or participation goal. Define strategies, coach in the natural context and monitor the experiences of all participants. Rotate and broaden the network when this supports natural participation.

Tier 3 — Individualised peer-mediated intervention

Develop a structured plan around the young person’s own goals, communication, access and safeguarding needs. Coordinate specialist and setting input; train peers and staff; specify prompting and fading; measure reciprocal outcomes and review willing participation. Complex needs do not justify transferring professional responsibility to classmates.

Practice example

This is a constructed illustration of the approach, not a reported case or an observed outcome.

Imagine a pupil who uses a communication device and wants a fuller role in a robotics club. The pupil and interested peers choose a project and agree how to share decisions. Adults support the group to make the device and materials available, leave time for messages and distribute meaningful roles. Both the pupil and supporting peers can decline a role, ask for a change or withdraw; adults retain responsibility for access and safety.

Review would record each person’s influence on decisions, whether messages were heard, adult takeovers, effort and the participants’ views. Collaboration at club would be a valid outcome in its own right. Friendship would be recorded only if the young people describe the relationship that way.

1. Why the evidence boundary matters

“Peer-mediated” describes who carries part of the intervention, not one programme. Studies include peer networks, peer supports, playground interventions, classwide approaches, peer tutoring and packages combining adult instruction with peer action. They differ in age, setting, peer number, dose, target and outcome.

The label should therefore never carry an undifferentiated efficacy claim. The record must specify the trained peer behaviour, adult support, context and outcome. An intervention that increases conversational turns is evidence for that result, not automatic proof of friendship or inclusion.

2. How the group and setting may matter

Peer groups create many natural opportunities for communication, shared attention, learning and status. They also contain fast rules, implicit expectations and barriers that adult-only teaching may not change. A peer-mediated approach changes this shared environment: it changes invitations, response, pacing, roles, access and the probability that a social attempt has a meaningful consequence.

This does not deny that a focal young person may want direct teaching or support. It prevents the intervention from treating social participation as a solo performance. Outcomes depend on peers, adults, activity design and the wider climate, including bullying and acceptance.

3. What systematic reviews show

A systematic review of group-design school studies identified five studies, four randomised, and reported social-skill improvements across them, while emphasising the small and varied evidence base. A later review of primary-school peer-mediated interventions located 24 articles and found positive findings in most studies that reported relevant outcomes.

The later review also identified familiar limits: small samples, design and reporting weaknesses, limited blinding, potential confounds and sparse student perspectives. Only five studies reported follow-up, with mixed maintenance. The evidence is promising rather than universally conclusive.

4. What controlled studies add

In a randomised school study involving 60 autistic children across 56 classrooms, the peer-mediated condition improved measures including social-network salience (how prominent a pupil is in the network of peer connections), friendship nominations, teacher-rated social skills and playground isolation, with some effects maintained at three months. This is stronger evidence than uncontrolled observation, but it remains one model, age range and school ecology.

Randomised work on peer networks and peer support arrangements has also reported improved interaction, communication or classroom engagement for autistic pupils and students with severe disabilities. The packages include adult facilitation, peer preparation and structured opportunities; their findings should not be reduced to “give the pupil a buddy”.

5. Interaction is not the same as friendship

A 2023 systematic review and meta-analysis of friendship interventions for children with neurodevelopmental conditions found a moderate favourable within-group pooled effect, but the pooled between-group effect was not statistically significant. Several interventions had negligible effects and friendship quality did not clearly improve.

Friendship is reciprocal, voluntary and partly private. Network nominations, time near peers or adult-coded exchanges may be valuable indicators, but none alone establishes friendship or belonging. If friendship is the claim, ask the young people and use measures that capture mutuality and quality. If the intervention improves participation in science club without producing a friendship, that can still be a worthwhile and honest result.

6. Implementation determines what was delivered

Effective-looking programmes typically do more than brief peers once. They identify meaningful contexts, recruit willing peers, teach and rehearse concrete strategies, create shared activities, coach in the moment, reinforce reciprocity and plan fading. Adults monitor and adapt rather than disappearing.

Document peer selection, consent and withdrawal; content and duration of training; activity; adult prompts; focal-young-person preparation; communication and environmental adjustments; generalisation; and debrief. Staff fidelity (delivery of the approach as intended) matters, but peer behaviour should not be policed so tightly that ordinary interaction becomes performance.

7. Minimum monitoring

Monitoring should connect implementation, outcome and experience:

• participation and assent: whether the focal young person and peers choose and continue the arrangement;
• implementation: peer strategies, adult coaching, activity access and prompt fading;
• reciprocity: who initiates, responds, contributes, leads, refuses and repairs;
• communication: successful messages, mode access, range and partner understanding;
• natural-context outcome: contribution, engagement, isolation, network access or the specific goal;
• relationship quality: direct reports of belonging, friendship or loneliness when those are claimed;
• maintenance and generalisation: what persists with fewer prompts, different peers and other settings;
• cost and harm: stigma, fatigue, unwanted attention, peer burden, dependency, conflict or bullying.

Adult tallies require interpretation. A rise in prompts or scripted initiations may inflate activity without improving autonomy. A smaller number of chosen, reciprocal interactions may be more meaningful.

8. Cautions, safeguarding and equity

Peers must not become unpaid care staff or hold responsibility for medication, physical assistance, behaviour control, confidential disclosure, transport or protection from harm. Adults retain safeguarding and instructional responsibility. If a peer hears a disclosure or sees risk, they need a simple route to a trusted adult—not an expectation to investigate.

Recruitment must avoid public labelling, diagnostic disclosure without permission, tokenism and moral rewards for befriending a disabled pupil. Protect peers from pressure to participate and the focal young person from being observed as a project. Rotate arrangements thoughtfully, but do not disrupt a naturally chosen relationship for programme convenience.

Attend to race, language, gender, sexuality, disability, social status and cultural norms. A young person may be excluded through discrimination rather than lack of skill. Communication systems and sensory access must be present. Anti-bullying action, adequate staffing and environmental adaptation cannot be outsourced to kind classmates.

9. What we can say

• Peers can be taught defined strategies that increase opportunities for reciprocal communication and participation.
• Reviews and controlled studies show promising school-based outcomes, including interaction, communication, social-network and isolation measures.
• National Institute for Health and Care Excellence (NICE) advises considering peer mediation for school-aged autistic children within a specified social-communication intervention.
• Shared interests, natural contexts, explicit peer preparation, adult coaching and planned fading are recurring implementation features.
• Outcomes should be defined around the young person’s chosen participation and the experience of all participants.
• Friendship and belonging require direct, reciprocal measures rather than inference from proximity or adult counts.

10. What we cannot say

• We cannot claim that all peer-mediated approaches are effective or interchangeable.
• We cannot infer friendship, belonging, reduced loneliness or wellbeing from more interactions alone.
• We cannot assume that a peer who agrees once remains willing or unburdened.
• We cannot transfer primary-school autism findings automatically to other ages, populations and settings.
• We cannot treat peer mediation as a substitute for communication access, environmental change, direct teaching, staffing or safeguarding.
• We cannot make peers responsible for changing the focal young person or for outcomes beyond their role.
• We cannot describe assigned proximity or unpaid helping as inclusion.

11. Review, exit and escalation

At review, ask whether all participants still want to take part; whether the trained peer and adult actions occurred; whether interaction was reciprocal and connected to the intended activity; whether the focal young person experienced greater control and belonging; whether prompts faded; and whether burden, stigma, dependency or conflict emerged.

Revise or stop when the arrangement is unwanted, artificial, burdensome, publicly identifying, ineffective or unsafe. A structured intervention can end when ordinary access is established, while universal inclusive routines continue. Do not terminate a naturally valued relationship because formal data collection ends.

Escalate when bullying, exploitation, safeguarding concerns, significant distress, communication breakdown, severe isolation or discriminatory practice is present; when peers are carrying adult responsibilities; or when specialist communication, mental-health, occupational or educational assessment is required. Peer mediation should sit within, not replace, an adequate support system.

12. Phoenix judgement

Peer-mediated approaches have promising findings for some outcomes, with important conditions around participation, choice and adult responsibility. The evidence supports structured programmes that prepare peers and create meaningful natural-context opportunities. It is less secure for durability, generalisation and the deepest outcomes often implied by the approach: friendship, belonging and wellbeing.

A proposed peer-mediated plan should make clear that the young person’s goal and willing participation are explicit, peers participate voluntarily, adult responsibilities are protected, strategies and activities are defined, communication and environmental access are in place, and review includes reciprocity and lived experience. Peers can open doors to participation; they must not be used as the door staff, therapist or proof that inclusion has occurred.

Shared evidence profile fields

For peer-mediated work, identify the programme or format, the recipient and supporting-peer roles, adult preparation and the participation outcome. A generic buddy arrangement is not an adequate description of the intervention studied.

The following fields make a specific evidence or implementation record comparable with other Atlas profiles. They do not supply missing study data or replace the source-specific judgements in this entry.

• Identity and version: Name the component or programme, its edition or protocol where relevant, and the purpose being evaluated.
• Source role: Separate direct comparative evidence, descriptive implementation findings, guidance, theoretical support and firsthand experience.
• Population and setting: Retain the studied age, communication/access characteristics and setting. State when an intended application lies outside them.
• Intended and actual delivery: Record the planned components, frequency and duration (dose) separately from what was received, by whom, and with what support or interruptions.
• Comparison and other support: Name the actual comparison and concurrent changes. If there is no comparison group or condition (comparator) or it is unreported, say so rather than supply an assumed usual-care condition.
• Outcome and reporter: Record the outcome, time point and reporter. Keep the young person’s account separate from someone else’s judgement on their behalf (proxy report), and access or participation separate from task performance.
• Delivery as intended (fidelity) and adaptation: Record whether the core components were delivered and describe adaptations; distinguish an adapted application from the protocol tested.
• Burden and unwanted effects: Record time, effort, practical access, cost or workload where known, alongside refusal, fatigue, distress, restriction and other unwanted consequences. Unreported burden is not evidence of no burden.
