Background:
The transition from primary to secondary school is a pivotal period in young people’s lives and can significantly impact their mental health. However, the experiences of young people from ethnically diverse groups during this crucial period of physical, social and emotional development are under-researched, limiting the evidence base for meaningful support.

Objectives:
This study explored the experiences of young people from ethnically diverse groups during primary-secondary school transition and co-designed ideas for culturally sensitive support. It explicitly focused on the intersection between ethnic and cultural identity, primary-secondary transition and mental health.

Methods:
The study employed participatory design to collaborate with seven young people from ethnically diverse groups and a peer researcher. Four online workshops mapped participant experiences and ideas concerning the primary-secondary transition, identity and mental health. These were developed into implications for practice, policy and research.

Results:
Participants highlighted feeling unprepared for the transition, with some experiencing poor mental health and difficulty navigating their ethnic and cultural identity during this time. Participants’ ideas for future transition experiences included: supporting a longer transition period, schools promoting diversity among students and staff, enabling education on ethnicity and culture, breaking stereotypes, enabling mutual learning among staff and students and enabling an open and caring environment to support mental health.

Conclusions:
The study provides an in-depth understanding of experiences of young people from ethnically diverse groups during primary-secondary transition and suggests ways of supporting multi-faceted transitions and mental health, with a key focus on ethnic and cultural identity formation.
