California PTKLF

The California Preschool/Transitional Kindergarten Learning Foundations (PTKLF) describe the learning and development of most children ages three to five and a half years old in high-quality early education programs.

The California Preschool/Transitional Kindergarten Learning Foundations (PTKLF) outline key knowledge and skills that most children ages three to five and a half years old 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 preschool and transitional kindergarten (TK) educators, parents, and the public with a clear understanding of the wide range of knowledge and skills that children typically attain when given the benefits of a high-quality preschool program, whether it be in center-based, home-based, or TK settings.

The Preschool Learning Foundations were originally released by the California Department of Education (CDE) in January 2008 (Volume 1), 2010 (Volume 2), and 2012 (Volume 3). In the 2021 Budget Bill, the CDE was given the authority to revise the Preschool Learning foundation (PLF). The revised PTKLF will be released on this webpage in the summer of 2024.

The newly revised publication reflects the latest research on child development in all domains: Math, Language & Literacy, Science, Social-Emotional Development, History Social-Science, Health, Visual Performing Arts, and Physical Development. The publication also includes key changes:

  • A greater emphasis on diversity, equity, and inclusion with more examples of children from different cultural backgrounds, children communicating in different languages, and child with disabilities.
  • The "Later Foundation" is now more inclusive of TK and provides a developmentally appropriate stepping stone towards the Kindergarten Common Core State Standards.
  • A new Approaches to Learning Domain which captures aspects of motivation, executive functioning, and goal-directed learning.
  • A Language & Literacy Domain with two sub-domains: Foundational Language Development (FLD) and English Language Development (ELD).
    • FLD describes the knowledge and skills in language and literacy for children in their home language (whether it be English or another language) - with examples of child speech in over 15 languages. ELD describes the trajectory of English language and literacy development for children who are English language learners.
  • Alignment between more examples in the "Early" and "Later" foundation skills to demonstrate the development progression.

Webinars

More detailed webinars for each domain will be scheduled for Summer 2024 following the release of the PTKLF.

California Preschool Learning Foundations, Volume 1

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.

On January 22, 2008, the California Department of Education (CDE) released the California Preschool Learning Foundations, Volume 1 (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, Tagalog, Spanish, and Vietnamese, and are based on the prevalent non-English languages spoken by parents of preschool children in California.
