A recent meta-analysis of almost 60 years’ worth of high-quality early childhood education (ECE) studies in the US found that participating in ECE programmes significantly reduced special education placement and grade retention (pupils having to repeat a year), and lead to increased graduation rates from secondary school.
Dana Charles McCoy and colleagues examined data from studies spanning 1960-2016. All had to meet strict inclusion criteria and address ECE’s effects on special education placement, grade retention, or dropout rates, yielding 22 studies. Seven were randomised controlled studies, four were quasi-experimental, and eleven used non-randomised assignment and compared groups who were equivalent at baseline.
Results showed statistically significant effects of ECE. Compared to pupils who did not attend ECE, participants were 8.1% less likely to be placed in special education, 8.3% less likely to be held back a year and 11.4% more likely to graduate from secondary school.
