Outcomes of early childhood education

The New Zealand Ministry of Education commissioned this literature review into the impact of early childhood education (ECE) on children and families. The authors explored 117 international and New Zealand texts to addresses three questions:

(a) What developmental, educational, social, and economic outcomes are associated
with participation in ECE for learners and their families?
(b) Are different outcomes associated with different population groups and under different circumstances/ contexts? Considering whether there are adverse impacts more likely and for whom?
(c) How do different outcomes interact/relate with one another?
i. What is the size/significance of the different impacts of ECE? How long do the effects last?

Key findings:

- ECE participation is positively associated with gains in mathematics and literacy, school achievement, intelligence tests, and also school readiness, reduced grade retention, and reduced special education placement.

- the small number of studies that examined associations between ECE participation and learning dispositions found positive impacts.

- There are mixed findings on the impact of ECE participation on antisocial and worried behaviour.

- There is a suggestion that children may catch more infections (ear, nose, and throat) through ECE participation, and that young children attending all-day centres may experience higher cortisol levels (symptom of stress). Where centres are good quality, cortisol levels tend to be lower.

- Studies found cognitive gains for children from low-income/ disadvantaged homes could be greater than for most other children in mathematics and literacy.

- Children for whom English is an additional language, and children from some ethnic minority groups (including Black children), made greater progress on numeracy and pre-reading measures during ECE participation than the white U.K. children or those for whom English is a first language in the English EPPE study.

- Longer duration of ECE experience is linked with cognitive (“academic”) gains for children from all family socioeconomic backgrounds but full-time attendance has no benefits for cognitive outcomes over part-time attendance in studies of children from a range of socioeconomic backgrounds.

- A small number of international studies found an early starting age before age 2 or 3 is associated with higher levels of antisocial or worried behaviour at the time of attendance or shortly after school entry. These associations were generally found in centres rated as low-quality.

As the diagramme shows, early childhood services that contribute to positive child and family outcomes are settings characterised by:
- intentional teaching;
- family engagement with ECE teachers and programmes, where social/cultural capital and interests from home are included, and both family and teachers can best support the child’s learning; and
- a complex curriculum involving both cognitive and non-cognitive dimensions
