In theory, school vouchers increase competition in the school system, giving all students the opportunity to choose the best learning environment. A look at voucher programs around the world reveals results.
As the demand for education increases, resources remain scarce. In most countries, the government is both the major financier as well as the provider of education. However, schooling still does not reach all members of society equally. One way of financing education is to provide families with the funding via cash transfers to schools based on enrollments, or by providing cash to families to purchase schooling. These are known as vouchers.
The objective of a voucher program is to extend the government’s financial support to any education provider and thus give all parents, regardless of income, the opportunity to choose the school that best suits their preferences. School choice via vouchers is often promoted as a means of increasing competition in the school system.
Advocates of the voucher system believe that competition will lead to efficiency gains, as schools—public and private—vie for students and try improving quality while reducing expenses. The idea is that when private schools are encouraged to attract students, they become innovative and thereby bring improvements to the learning process. Likewise, public schools, to attract students and the resources that come with them, seek to improve themselves to provide an education on par with the private schools.
On the other hand, opponents believe that under a voucher system, private providers will be unaccountable to taxpayers and the public. They question claims of efficiency gains. They assert that choice will lead to privatization, less public control of education, and increased segregation. While all these concerns need to be taken into consideration, the decision on how to finance education should be based on evidence.
Targeted vs Universal Vouchers
Colombia has a targeted voucher system. The Program for the Expansion of Secondary Education Coverage (PACES) was launched in 1991 to provide the poorest third of the country’s population access to secondary education. The program was oversubscribed, so students selected by a lottery were provided with vouchers to attend private schools. Municipal governments provided 20 percent of the funding for PACES; the federal government provided the remainder.
The program, which ran until 1997, covered 125,000 children in 216 municipalities. The unit cost per student for participating private schools was 40 percent lower than for non-participating private schools. The lottery allocation provided researchers with a natural experiment. Findings from the analysis showed that voucher beneficiaries have higher educational attainment. When compared with non-voucher students, voucher students were 6 percent less likely to repeat a grade; they scored 0.2 standard deviations higher on achievement tests and they were 20 percent more likely to take the college entrance exam. They were also less likely to be married and earned more in wages.
Chile’s universal voucher program has been active since 1980. Every municipality receives individualized monthly grants based on the number of students attending class in its schools. The municipal authorities also fund student attendance at subsidized private schools, which parents can choose. While test scores are similar in both public and private schools, after controlling for socioeconomic status, unit costs are lower in subsidized private schools.
Research on Chile’s voucher program has been subject to a high level of scrutiny. Though there are no randomized trials or rigorous impact evaluations, research results have been varied but trend positive.
The Netherlands is another country which illustrates the effectiveness of vouchers. Seventy percent of the enrollments are in government-financed private schools. On average, these students tend to be from families which belong to a lower socioeconomic class when compared to pupils attending public school, and yet test scores achieved are higher. The level of choice offered, alongside fixed funding from the government per student (with additional funding for disadvantaged students) appears to provide incentives for Dutch schools to keep improving. At the same time, given the need for schools to compete for students by demonstrating success, there’s no evidence of grade inflation.
These examples demonstrate that vouchers have the potential to help countries improve their education systems. But they do so within a context that requires more research to understand how they work, if they work, and for whom they work.
