India should invest in its youngest learners
A rethink about early learning in anganwadis and play schools is needed.
As much as 85% of brain development happens before the age of six. A birth cohort study in Vellore has shown a 5-point IQ increase among pre-school age children who underwent stimulation and learning through structured early childhood development (ECD) programmes compared with those who did not. Global research shows that millions of neural connections form every second at this age and that ECD has a 10-20% impact on high-school completion rates and lifetime income, which is why it is often classed as the intervention with the highest social return on investment.
