State spending on preschool more than doubled between 2002 and 2016, from $3.3 to $7.4 billion (constant 2017 dollars). However, a range of research also shows that many early childhood programs do not have positive long-term effects. For example, the Tennessee Voluntary Prekindergarten Program showed some positive effects for children as they finished their pre‐k school year; but, these positive were largely gone by the end of kindergarten. Program quality likely affects whether programs benefit children and recent investments have focused heavily on quality improvement.
