Putting a bunch more kids in Head Start is not what's being proposed here. The main proposal is a partnership with states to ensure that all four-year-old kids from moderate and low-income families have access to quality preschool.
Preschool children develop physically through running, jumping and climbing. Play is their context for deep learning and it is critical in preschool. Let's avoid the teacher-directed and worksheet-heavy model of the preschool classroom. Let's get it right.
