Choosing a nursery or childcare setting is one of the most consequential decisions families make in the early years. The anxiety around this decision is understandable and, to a degree, appropriate: the quality of early childcare does affect developmental outcomes, particularly for children from disadvantaged backgrounds. But understanding what quality actually consists of – and looking past the things that are easy to see (nice rooms, good food, a garden) to the things that matter most – is where the most useful guidance lies.

What Research Shows About Quality
The Effective Pre-School and Primary Education (EPPE) study, conducted by Kathy Sylva at the University of Oxford and colleagues, is the largest and most comprehensive study of early childcare quality in the UK context. Its findings are consistent and clear: the quality of early childcare has a meaningful and lasting effect on children's cognitive and social development, and the effects are largest for children from disadvantaged backgrounds. The study identified several features of high-quality settings.
Staff qualifications and ongoing professional development. Settings with graduate-level staff (or at minimum staff who had undertaken relevant childcare training to a high level) consistently produced better outcomes. This is not because a degree automatically creates better interactions – it is because the conceptual understanding of child development that comes with higher-level training tends to produce more responsive, developmentally appropriate practice. The EPPE report was influential in raising qualification requirements in the UK early years sector.
Warm, responsive, stimulating interactions. The quality of what staff actually say and do with children – not the quality of the resources – is the strongest predictor of outcomes. Staff who get on the floor with children, use extended conversation, ask open-ended questions, follow the child's lead in play, and narrate what children are doing engage children's language and thinking in ways that benefit development.
Adult engagement in child-initiated activities (EICA). Settings where adults join in and enrich child-initiated play – asking questions, extending the narrative, providing vocabulary, introducing challenges – showed significantly better outcomes than settings where adults primarily managed children's time with structured activities or left them to play independently.
The learning environment. Access to open-ended materials, outdoor space, books, and varied sensory experiences supports exploration and learning. Cluttered or impoverished environments limit the opportunities for the kind of play that develops cognition and language.
The Key Person System
The EYFS (Early Years Foundation Stage) requires every child in a Registered setting to have a named key person – a member of staff who takes primary responsibility for that child's care and development, builds a relationship with them and their family, and serves as the child's secure attachment figure within the setting.
Research by Peter Elfer at the University of Roehampton on the key person system in UK nurseries documents that the quality of the key person relationship is a significant determinant of how settled children are, how well they develop within the setting, and how their emotional wellbeing is supported through transitions. A key person who knows the child well – their interests, temperament, routines, and family context – can respond to them much more sensitively than a setting in which children rotate between multiple carers without continuity.
When visiting settings, asking about key person ratios (how many children each key person is responsible for), how key persons are involved in daily care routines (nappy changes, feeding, settling to sleep), and what happens when a key person is absent are all useful indicators.
What to Look for on a Visit
Ratio and group size: the legally required adult-child ratios are minimums, not optimal targets. Settings that maintain lower ratios than required, particularly for the youngest children, tend to produce better interactions.
Observe interactions rather than facilities: is the setting stimulating without being chaotic? Are staff getting on the children's level – physically and conversationally? Are children's attempts to communicate responded to with warmth and engagement?
Ask about staff turnover: high turnover in a nursery means that key person relationships are frequently disrupted, which undermines the attachment security that is the foundation of everything else. A setting where staff have worked for several years and genuinely know the children is more valuable than a bright new building.
Ofsted grades: An "Outstanding" grade indicates a setting that performed well at a particular point in time; it is useful information but not definitive. Some "Good" settings have warmer interactions and more consistent staff than some "Outstanding" ones. Use the Ofsted report as one piece of information, not the whole picture.
Key Takeaways
Research on nursery quality identifies staff-child interactions as the most important determinant of developmental outcomes – more important than facilities, resources, or Ofsted grade alone. The Effective Pre-School and Primary Education (EPPE) study, the UK's most comprehensive research on childcare quality, found that the highest quality settings involved trained staff, warm and stimulating interactions, and adult engagement in child-initiated activities. The key person system, in which each child has a named member of staff primarily responsible for their care, is a EYFS requirement and is strongly associated with attachment security in childcare. Parents visiting a setting should observe interactions, not just facilities.
