Plain English summary of protocol
Background and study aims
Pupil attendance in schools is a matter of great concern in England and Wales. While the reasons for school absence are complex, bullying, lack of safety at school, and school conflict are among them. The Grassroots programme aims to improve school attendance by reducing conflict and bullying behaviours in schools.
Who can participate?
Young people in school years 7-9 attending mainstream state-funded secondary schools in the recruitment areas.
What does the study involve?
Pupils in the treatment group will complete a survey in which they identify pupils they have chosen to spend time with. The best-connected pupils in each school will be invited to join a Change Makers group and attend 10 fortnightly intervention sessions with a facilitator to develop anti-conflict interventions tailored to their school. This will include handing out wristbands for engaging in friendly or anti-conflict behaviour, displaying posters with anti-conflict messages, sharing anti-conflict messages online, modelling pro-social behaviours and talking with peers about how to reduce conflict.
What are the possible benefits and risks of participating?
It is hoped that being part of a Change Makers group will be enjoyable and may improve pupils' experiences of school. Being part of a Change Makers group will mean missing a small number of lessons (10).
Where is the study run from?
The Grassroots programme is being run by a team from Behavioural Insights Limited (UK). Regional facilitators will lead Change Makers sessions in schools.
When is the study starting and how long is it expected to run for?
January 2023 to January 2027
Who is funding the study?
1. Youth Endowment Fund (UK)
2. Education Endowment Foundation (UK)
Who is the main contact?
1. Dr Becky Taylor (UCL) is the main contact for the evaluation (becky.taylor@ucl.ac.uk)
2. Dr Kathryn Atherton (Behavioural Insights Ltd) is the main contact for the Grassroots programme

| Scientific title | Grassroots Efficacy Trial: Evaluation of an anti-conflict intervention by cluster randomised controlled trial |
| Study acronym | Grassroots |
| Study objectives | The Grassroots intervention reduces conflict and bullying behaviours among pupils and so reduces pupil absence from school. |
| Ethics approval(s) |
Approved 24/03/2023, IOE Research Ethics Committee (UCL) (20 Bedford Way, London, WC1H 0AL, United Kingdom; +44 (0)20 7679 2000 (switchboard); ioe.researchethics@ucl.ac.uk), ref: REC1773 |
| Health condition(s) or problem(s) studied | Improving school attendance through reduction of conflict and bullying behaviours in 11-14-year-old adolescents in secondary schools in England and Wales |
| Intervention | The Grassroots programme (adapted from ROOTS, Paluck et al., 2016) will be implemented in schools and randomised on a 1:1 basis. The randomisation procedure placed half of participating schools in each region (North West, Midlands, London, West England and South Wales) in the intervention arm and half in the control. A seed in R was used to generate random numbers for each school (listed alphabetically) and schools with the lowest random numbers in each of the five regions were allocated to the intervention arm. Pupils in the treatment group will complete a survey in which they identify pupils they have chosen to spend time with. The best-connected pupils in each school will be invited to join a Change Makers group and attend 10 fortnightly intervention sessions with a facilitator to develop anti-conflict interventions tailored to their school. This will include handing out wristbands for engaging in friendly or anti-conflict behaviour, displaying posters with anti-conflict messages, sharing anti-conflict messages online, modelling pro-social behaviours and talking with peers about how to reduce conflict. The control group is business as usual. |
| Intervention type | Behavioural |
| Primary outcome measure(s) |
School attendance is measured as the percentage of school sessions attended in a term from the National Pupil Database (England) and SAIL databank (Wales) at baseline (Autumn term 2023), post-intervention (Summer term 2023), and 1 year (Autumn term 2025) |
| Key secondary outcome measure(s) |
1. Bullying victimisation, cyberbullying victimisation, bullying perpetration and cyberbullying perpetration are measured using the four subscales of the Bullying and Cyberbullying Scale (for adolescents) at baseline and post-intervention |
| Completion date | 31/01/2027 |
