High turnover rates can have a negative effect on ECEC quality since staff provision is less stable, which, in turn, can impact child development. When staff members regularly change within a group of children, staff and children are less able to develop stable relationships, and nurturing, stimulating interactions take place less often (CCI, 2006). This is mainly because there is a complex inter-relationship between staff-child ratios, staff qualifications, quality and type of provision that makes it difficult to single out the effect of a particular characteristic of working conditions (Sammons, 2010). Available research findings focus on the effects on staff satisfaction rather than on child development.
