This article reviews international evidence of the determining factors for a successful transition from primary to secondary school. Studies worldwide have identified a strong and supportive pupil-family-teacher relationship as one of the most crucial influential factors for a positive transition with regards to both social and academic challenges many pupils experience. Studies on the transition experience suggest that, when designing supportive policies for future transition, it is essential to let pupils’ voices be heard and involve parents in the process. This evidence aligns with research on Scottish children’s experience of the transition. People Know How and their Positive Transitions service has already played an important role in facilitating good transition experiences for young people across Edinburgh and East Lothian – involving pupils in the design of projects to ensure they are as helpful and relevant as possible. With their strong connections with young people, their families and communities, their service is an innovative example of supplementary support during the transition period.
