State early childhood education programs: Low-income

Pre-K to 12 Education
Benefit-cost methods last updated December 2024.  Literature review updated July 2019.
To be considered a pre-kindergarten program, the program must have had an age requirement of three or four at the start of the program and an education focus. This analysis includes studies of children attending a state- or district-funded pre-kindergarten programs that target low-income students after 1975. Programs examined offered ECE services on a part-time and/or full-time basis. Comparison students may have received child care provided by family or non-family members, another preschool program, or Head Start.

We exclude programs that provided childcare subsidies, focused on the provision of general childcare, focused on parent and child development, and/or provided more extensive wraparound services.

For an overview of WSIPP's Benefit-Cost Model, please see this guide. The estimates shown are present value, life cycle benefits and costs. All dollars are expressed in the base year chosen for this analysis (2023).  The chance the benefits exceed the costs are derived from a Monte Carlo risk analysis. The details on this, as well as the economic discount rates and other relevant parameters are described in our Technical Documentation.
Benefit-Cost Summary Statistics Per Participant
Benefits to:
Taxpayers $3,724 Benefits minus costs $13,144
Participants $9,713 Benefit to cost ratio $4.78
Others $5,119 Chance the program will produce
Indirect ($1,937) benefits greater than the costs 91%
Total benefits $16,619
Net program cost ($3,475)
Benefits minus cost $13,144

^WSIPP’s benefit-cost model does not monetize this outcome.

Meta-analysis is a statistical method to combine the results from separate studies on a program, policy, or topic to estimate its effect on an outcome. WSIPP systematically evaluates all credible evaluations we can locate on each topic. The outcomes measured are the program impacts measured in the research literature (for example, impacts on crime or educational attainment). Treatment N represents the total number of individuals or units in the treatment group across the included studies.

An effect size (ES) is a standard metric that summarizes the degree to which a program or policy affects a measured outcome. If the effect size is positive, the outcome increases. If the effect size is negative, the outcome decreases. See Estimating Program Effects Using Effect Sizes for additional information on how we estimate effect sizes.

The effect size may be adjusted from the unadjusted effect size estimated in the meta-analysis. Historically, WSIPP adjusted effect sizes to some programs based on the methodological characteristics of the study. For programs reviewed in 2024 or later, we do not make additional adjustments, and we use the unadjusted effect size whenever we run a benefit-cost analysis.

Research shows the magnitude of effects may change over time. For those effect sizes, we estimate outcome-based adjustments, which we apply between the first time ES is estimated and the second time ES is estimated. More details about these adjustments can be found in our Technical Documentation.

1In addition to the outcomes measured in the meta-analysis table, WSIPP measures benefits and costs estimated from other outcomes associated with those reported in the evaluation literature. For example, empirical research demonstrates that high school graduation leads to reduced crime. These associated measures provide a more complete picture of the detailed costs and benefits of the program.

2“Others” includes benefits to people other than taxpayers and participants. Depending on the program, it could include reductions in crime victimization, the economic benefits from a more educated workforce, and the benefits from employer-paid health insurance.

3“Indirect benefits” includes estimates of the net changes in the value of a statistical life and net changes in the deadweight costs of taxation.

The cost of participation in early childhood education programs targeting low-income children are estimated from Washington’s Early Childhood Education Assistance Program (ECEAP) for low-income preschoolers (2019-20 ECEAP Contractor Slots, Models, Overincome Allotments, and Funding https://www.dcyf.wa.gov/sites/default/files/pdf/eceap/ECEAP_Contractor_slots_models_funding.pdf). The comparison group cost consists of an estimate of all ECEAP/Head Start-eligible children in Washington who are participating in Head Start, receiving state-funded childcare subsidies, or receiving no state-funded care. The cost of Head Start participation was provided by T. Saenz-Thompson (personal communication, Office of Head Start Region 10, October 24, 2019). The cost of receiving state-funded childcare subsidies is based on Washington’s childcare subsidy reimbursement rates as of February 2019 (https://www.dcyf.wa.gov/node/1640). The comparison group cost is a weighted average of the cost of Head Start, state-subsidized childcare, and no state-funded care.
The figures shown are estimates of the costs to implement programs in Washington. The comparison group costs reflect either no treatment or treatment as usual, depending on how effect sizes were calculated in the meta-analysis. The cost range reported above reflects potential variation or uncertainty in the cost estimate; more detail can be found in our Technical Documentation.

Benefits Minus Costs Over Time (Cumulative Discounted Dollars)
The graph above illustrates the estimated cumulative net benefits per-participant for the first fifty years beyond the initial investment in the program. We present these cash flows in discounted dollars. If the dollars are negative (bars below $0 line), the cumulative benefits do not outweigh the cost of the program up to that point in time. The program breaks even when the dollars reach $0. At this point, the total benefits to participants, taxpayers, and others, are equal to the cost of the program. If the dollars are above $0, the benefits of the program exceed the initial investment.
