The California Preschool Learning Foundations outline key knowledge and skills that most children can achieve when provided with the kinds of interactions, instruction, and environments that research has shown to promote early learning and development. The foundations can provide early childhood educators, parents, and the public with a clear understanding of the wide range of knowledge and skills that preschool children typically attain when given the benefits of a high-quality preschool program.

The foundations were developed using an inclusive and deliberative input process, including statewide stakeholder meetings, public input sessions held throughout the state, public hearings, and public comment. Input from the various review opportunities was considered and incorporated as appropriate.

California Preschool Learning Foundations, Volume 1

On January 22, 2008, the California Department of Education (CDE) released the California Preschool Learning Foundations, Volume (PDF; 5MB) . Former State Superintendent of Public Instruction Jack O'Connell stated that these foundations offer our early childhood educators a clear understanding of what our youngest learners should know before entering kindergarten.

Volume 1 of the California Preschool Learning Foundations focuses on the domains of social-emotional development, language and literacy, English-language development, and mathematics. They provide a comprehensive understanding of what children learn in these four domains.

In an effort to partner with parents in the education of their preschool children, key sections of the publication are available and have been translated to support parents' understanding of the preschool learning foundations, their purpose, and what they describe as the knowledge and skills that children typically attain at 48 and 60 months of age. The translations include traditional Chinese, simplified Chinese, Hmong, Korean, Pilipino (Tagalog), Spanish, and Vietnamese, and are based on the prevalent non-English languages spoken by parents of preschool children in California.
