The "Start Plan" in the United States is an early childhood development project, which aims to provide education, medical care and physical health services for children aged 3-4 from poor families, help them overcome the obstacles of poverty and better prepare for primary education. The plan was implemented by the federal government, state governments and local agencies in the summer of 1965. It is one of the earliest preschool education projects in the United States, and it is a far-reaching preschool education research and practice.

The principles and organizational forms of the "Start-up Plan" include nine aspects: high quality, prevention and promotion, benign interaction and persistence, parents' participation and community cooperation. There are three forms of organization: nursery-based programs, family-based programs and mixed programs. Since 1990s, the "Beginning Plan" has taken various improvement measures to promote the development of their reading and writing ability, including highlighting the dominant position of preschool children, optimizing preschool curriculum model, integrating reading and writing teaching contents, improving the quality of preschool teachers, expanding diversified training paths, promoting family cooperation of preschool children and advocating parent-child sharing reading.

In a word, the "Start Plan", as a landmark early childhood development plan in the United States, has provided important support for improving the lives and development of poor children, and also provided valuable experience for the research and practice in the field of preschool education.
