The Early Learning Study at Harvard is a large-scale, population-based study that examines children's development in the context of their learning experiences.
Household Survey in progress!

To deliver on the promise and potential of early education at scale, we need to bring the science of early learning up-to-date in two major ways. First, the science must match the demographics of today’s children, given increasing immigration rates and the linguistic and economic diversity among the U.S. population. Second, we need to capture the variety of settings in which children are learning and growing. Only then are we positioned to address the big questions and concerns facing the field, including that of “fade out”—the observation that positive effects of exposure to high-quality early education are not maintained through the school years—and those of scale, including what models work, for whom, and under what conditions.
Our Key Questions
What learning outcomes and developmental gains can we expect from early learning environments? Which of these outcomes are particularly sensitive to high-quality environments and how do they vary by characteristics of the population?
What are the features of early schooling that maintain and multiply the benefits of preschool? What practices undermine those benefits?
