The 2025-26 Budget:
Transitional Kindergarten
GABRIEL PETEK | LEGISLATIVE ANALYST | FEBRUARY 2025
SUMMARY
Governor Proposes $1.8 Billion in Additional Funding for Final Year of Transitional Kindergarten
(TK) Expansion. This brief provides an overview and analysis of the Governor’s proposals for TK.
The Governor’s budget increases funding by $1.1 billion to implement the final year of TK expansion.
This would provide additional funding through the Local Control Funding Formula (LCFF) for the anticipated
increase in TK students and the higher add-on costs associated with maintaining a 1-to-12 adult-to-student
ratio. The Governor also proposes to increase funding by $746 million for school districts and charter schools
to meet one-to-ten staffing ratios in TK classrooms, a requirement set to start in 2025-26. (For brevity, we
refer to both school districts and charter schools as districts throughout this brief unless otherwise noted.)
Recommend Providing a Lower Amount of Funding for Add-On Costs. The Governor’s proposed
add-on funding to meet the one-to-ten staffing ratio is likely higher than the costs of the requirement.
We developed two estimates of staffing costs aligned with the two main ways districts are likely to adapt to
the new requirement. One estimate assumes that districts keep TK class sizes at 24 and add a third adult
in the classroom, which would effectively result in a staffing ratio of one adult for every eight students.
We estimate this approach would cost $196 million less than the administration’s proposed funding.
A second estimate assumes districts reduce TK class sizes to 20 and keep two adults in each classroom.
We estimate this would cost $410 million less than the administration proposes (though districts may have
some associated one-time costs to increase the number of classrooms). We recommend the Legislature
adopt one of these two alternatives, which would free up Proposition 98 funding the Legislature could use for
other school priorities.

State Has Several Penalties Related to
Transitional Kindergarten (TK) Program Requirements
The State Has Three Penalties for TK. Since 2022-23, districts can incur penalties for
noncompliance with TK program requirements related to the maximum class size and the
minimum number of adults in the classroom. Starting in 2025-26, districts will also incur penalties
if they do not comply with TK teacher education requirements. The figure below explains these
penalties in greater detail. Each penalty targets a specific aspect of the Local Control Funding
Formula; however, the class size penalty is unique because noncompliance results in loss
of the entire grade span adjustment. The other two penalties are based on the rate at which
noncompliance was observed.

The State Monitors District Compliance Through Annual Auditing. The state monitors
district compliance with TK program requirements through the annual auditing process. Auditors
will review a representative sample of schools within a district to determine if it has complied with
the statutory program requirements. As an example, for a district with 15 school sites, auditors
may review the TK program at four schools to determine compliance for the entire district.
Current Penalty Structure Has Trade-Offs. Compared with other elementary grades, the
state provides higher levels of funding for TK, as well as stricter requirements with relatively
stringent penalties for noncompliance. Higher penalties may put pressure on district budgets, but
also create a financial incentive for districts to comply. In some cases, this could have the effect
of encouraging districts to prioritize TK staffing over other grades. For example, districts with
challenges hiring instructional aides may reduce the number of aides in other grades to ensure
compliance with TK staffing ratios. As TK fully expands, the Legislature may want to continue to
monitor these various trade-offs to ensure that the current structure aligns with the Legislature’s
priorities for staffing at schools.
