California has significantly transformed its Early Care and Education (ECE) landscape since 2019 through the implementation of Universal Pre-Kindergarten (UPK). The state has phased in Universal Transitional Kindergarten (TK), expanding access to a school-based early learning experience for four-year-olds. This expansion is supported by the Expanded Learning Opportunities Program (ELO-P), which provides before-school, after-school, and intersession care to children from low-income families. State investments in subsidized programs across the early childhood mixed delivery system, including the California State Preschool Program (CSPP), general child care and development programs, Head Start, and private providers, continue to give families options and remain the primary mechanism through which low-income children under age four are served.
This expansion, however, has moved faster than the systems needed to support it. The rapid pace has further exposed long-standing challenges across the ECE system. Fragmented oversight, significant data gaps, and an unevenly prepared and compensated workforce continue to make it difficult to monitor, evaluate, and improve programs despite billions in public investment. California has taken steps to address some of these systemic issues by developing the PK-3 ECE Specialist Instruction Credential, revising the Child Development Permit, and updating the preschool/TK learning foundations to better align with K-3 standards. Even so, major initiatives, including TK and state preschool, have moved forward without dedicated resources to evaluate their implementation or effects.
Investments in Transitional Kindergarten and state preschool offer clear benefits, including the potential to narrow achievement gaps and relieve some of the financial stress facing California families. At the same time, the movement of four-year-olds into TK may destabilize community-based providers that rely on older children to subsidize the high cost of infant and toddler care. California also lacks the preschool-through-third-grade infrastructure needed to sustain and build on early gains, including aligned data systems, curriculum, assessments, and teacher preparation requirements and ongoing professional learning support. Although the state’s recent accomplishments reflect a serious commitment to young children’s learning and development, their long-term impact will depend on effective implementation across programs. Without evaluation resources, integrated data systems, and unique identifiers for children and educators, California cannot accurately track enrollment, assess program quality, or measure long-term outcomes.
The challenge for California now is not simply to expand access further, but to ensure quality and continuity of care in a complex, multi-agency system that families and providers often struggle to navigate. This brief, drawing on Getting Down to Facts III reports, describes the current state of ECE in California and what will be required to move forward. At the heart of that challenge are three recurring issues in the research: fragmented governance, uneven workforce preparation and compensation, and weak data infrastructure. The central issue now is whether California’s expansion efforts are being matched by the coherence and quality needed to support children from birth through third grade.
Key Findings
1. Universal Transitional Kindergarten has expanded access to early learning for California’s four-year-olds, although access remains uneven.
Enrollment in TK among eligible four-year-olds is high, and available evidence suggests that participation benefits children while easing financial pressure for many families. At the same time, not all families are aware that TK is an option, and others continue to face barriers to enrollment.
2. Investment in Universal Pre-Kindergarten improves child outcomes for most students.
California has invested heavily in early childhood education, especially through TK and CSPP. These investments have produced substantial, equity-enhancing gains in student achievement and appear to reinforce one another alongside TK–12 investment through the Local Control Funding Formula across the preschool and early elementary years.
3. Significant supply gaps persist for infants, toddlers, and three-year-olds.
California continues to face major shortages in care for children under four. TK expansion has raised concern among some providers because many rely on older, less expensive children to subsidize the cost of infant and toddler care, and the gap between the supply of and demand for those slots remains substantial despite recent investments in CSPP and child care.
4. Preparation requirements vary widely across ECE settings, and ongoing professional support remains limited and fragmented.
Requirements for teachers and caregivers differ significantly across programs and do not always align with children’s developmental needs. California’s expectations for lead teachers in state preschool remain low relative to most states, and professional development is typically not organized around the job-embedded and sustained approaches that research has found most effective. Meanwhile, TK teachers are held to higher preparation requirements than teachers of 4-year-olds in many states.
5. Workforce support has improved, especially in TK, but compensation and training pathways across the broader ECE sector remain inadequate.
California has made meaningful progress in supporting the ECE workforce through reimbursement increases and expanded access to TK, where educators earn K–12-equivalent wages. However, compensation, preparation pathways, and working conditions remain inequitable and inadequate across much of the broader ECE workforce, contributing to staffing shortages and high turnover.
6. Oversight of ECE remains fragmented across state agencies, limiting accountability, support, and preschool-through-third-grade coherence.
Responsibility for ECE is split across multiple funding streams and agencies, creating a misaligned system for providers that rely on multiple funding sources. This fragmentation complicates efforts to align preschool with the early elementary grades and leaves monitoring and improvement efforts limited, duplicative, and often focused more on compliance than meaningful quality improvement.
7. California lacks the integrated statewide data infrastructure needed to evaluate quality and support continuous improvement.
Although the state has made substantial investments in ECE, fragmented and ineffective data systems limit its ability to assess participation, quality, coordination, and long-term outcomes. Without reliable, systematic, and integrated data, California cannot answer basic questions about how well the system is working or whether its investments are being used effectively.
