Do the benefits fade out or not? Understanding influences on short and long-term effects of preschool programmes

Drawing on global and local research, this Insights Brief unpacks influences on the short and long-term effects of preschool programmes and identifies the types of early learning programmes and education systems most likely to deliver lasting impact.

It’s the first publication from DataDrive2030’s Insights Lab series. Essential reading for policymakers, funders, researchers and programme designers who want to understand what makes the gains from ECD sustainable – and what leads to “fadeout” over time.

KEY INSIGHTS

• Short-term gains don’t always last: Without strong schooling, early ECD advantages can diminish by Grade 3.
• Quality and timing are crucial: Well-designed programmes that match children’s developmental stages deliver more lasting gains.
• System-level support sustains impact: Strong follow-on environments, especially quality primary schooling, reduce fadeout.
• International models show it’s possible: Mexico’s preschool reform achieved sustained gains.
