Almost all 3- and 4-year-olds in Scotland now experience some form of pre-school provision prior to school entry. Given such high rates of participation, the impact of pre-school experiences on children's readiness for primary school has become an important issue for those involved in the early stages of compulsory schooling. Teachers in early years classes need to be aware of the experiences and achievements of individual children in their pre-school setting to enable each child to transfer into mainstream education with the least amount of disruption to their learning. This study was carried out in one small Scottish local authority and explored the perceptions of early years teachers, from a diverse range of primary schools, of what information is important for them as children start school. This article presents the perspectives of Primary 1 teachers on children's readiness for schooling. It reports the factors, which these teachers identified as having an impact on successful transition from the pre-school setting into the primary school.
