The Hidden Costs of Private School Vouchers

Many states are rapidly expanding private school voucher programs, offering families public funds to pay for private education. While lawmakers often present these programs as a simple win for school choice, the financial reality is much more complicated. When states roll out universal vouchers, hidden costs quickly emerge for taxpayers, public school districts, and the parents participating in the programs.

State Budget Deficits and Taxpayer Burdens

The most immediate hidden cost of expanding private school vouchers statewide is the impact on state budgets. When states remove income caps and open voucher programs to all students, the cost projections almost always fall short of reality.

A clear example is Arizona. In 2022, Arizona expanded its Empowerment Scholarship Account (ESA) program to all students. Lawmakers originally estimated the expansion would cost around $65 million for the 2024 fiscal year. Instead, the program exploded in popularity, mostly among families whose children were already attending private schools. The cost quickly approached $900 million, contributing directly to a massive state budget shortfall.

Florida experienced a similar surge. After expanding the Family Empowerment Scholarship to all students, the state faced program costs exceeding $3 billion in a single year. Because public funds are finite, these massive cost overruns often force states to cut funding from other critical services like infrastructure, public safety, or higher education.

Out-of-Pocket Realities for Parents

Vouchers rarely cover the full cost of a private education. Parents who accept a voucher often discover a steep financial gap they must cover themselves.

Most state vouchers provide between $6,000 and $8,000 per student. However, the national average for private K-12 tuition is roughly $12,500, with high school tuition often exceeding $16,000. For a family earning a median income, paying the remaining $4,000 to $8,000 per child is simply impossible.

Beyond base tuition, private schools routinely charge additional fees that vouchers do not cover. Parents are frequently responsible for:

• Application and testing fees: Often ranging from $50 to $200 just to apply.
• Uniforms: Mandated daily wear can cost $300 to $600 per year.
• Technology fees: Charges for school-issued laptops or tablets, which can add $200 to $500 annually.
• Extracurricular costs: Mandatory fees for sports, arts programs, or field trips.

The Crushing Weight of Stranded Costs

When students leave public schools using a voucher, the public school loses the per-pupil funding attached to that student. However, the public school’s operating expenses do not drop at the same rate. Financial experts call these “stranded costs.”

Imagine a public elementary school with a fourth-grade class of 25 students. If three students leave to attend a private school using vouchers, the district might lose $24,000 in state funding. However, the school cannot fire three-twenty-fifths of a teacher. The school still has to heat the building, pay for the electricity, maintain the roof, and run the buses. The fixed costs remain exactly the same, but the school now has less money to cover them. This financial drain forces public schools to cut elective programs, delay facility repairs, or increase class sizes to make ends meet.

The High Cost of Transportation

Public schools are required to provide free transportation for students living within their district. Private schools rarely offer this service. When a parent accepts a voucher, they take on the hidden logistical and financial cost of getting their child to and from school every day.

Driving a child to a private school 10 miles away adds up to 40 miles of driving per day. Over a 180-day school year, that is 7,200 miles. Using the standard IRS mileage rate of 67 cents per mile, a parent is spending roughly $4,800 a year on gas, vehicle wear, and maintenance. This does not even account for the lost wages or missed work hours required to manage morning drop-offs and mid-afternoon pickups.

Special Education Surcharges

Under the federal Individuals with Disabilities Education Act (IDEA), public schools must provide special education services to students with disabilities at no cost to the parents. Private schools are not bound by this federal law.

When parents of a child with special needs use a voucher to switch to a private school, they often forfeit their federal IDEA protections. If the private school accepts the student, they will likely charge extra for necessary accommodations. Parents may find themselves paying out-of-pocket for a dedicated paraprofessional, speech therapy sessions, or specialized reading tutors. These services can easily cost upwards of $10,000 a year, quickly wiping out the financial benefit of the state voucher.

Frequently Asked Questions

Do private school vouchers cover the full cost of tuition?

In most cases, they do not. The average state voucher provides around $7,000 per student. Because average private school tuition exceeds $12,000, parents are usually required to pay the difference out of their own pockets.

How do vouchers affect public school funding?

When a student uses a voucher, the state transfers a portion of public education funds to a private institution. The public school loses that per-pupil funding, but they still have to pay fixed operating costs like building maintenance, utilities, and teacher salaries.

What are stranded costs in education?

Stranded costs are the fixed expenses a public school district must continue to pay even when enrollment drops. A school cannot easily reduce its heating bill or cut a teacher’s salary just because a few students leave for private schools.

Are special education services covered by private school vouchers?

Generally, no. Private schools do not have to provide free special education services. Parents using a voucher for a child with an Individualized Education Program (IEP) will likely have to pay extra fees for speech therapy, occupational therapy, or one-on-one aides.
