Iowa's Statewide Voluntary Preschool Program for Four-Year-Old Children (SWVPP) is an important part of the state's comprehensive early childhood effort, providing more opportunities for young children to access quality preschool and enter school ready to learn. The preschool programs are expected to serve four-year-old children with a range of abilities representing the social, linguistic, cultural, and economic diversity of families within the communities.
