In this article, we review the empirical evidence on the impact of education vouchers on student achievement, and briefly discuss the evidence from other forms of school choice. The best research to date finds relatively small achievement gains for students offered education vouchers,most of which are not statistically different from zero. Further, what little evidence exists regarding the potential for public schools to respond to increased competitive pressure generated by vouchers suggests that one should remain wary that large improvements would result from a more comprehensive voucher system. The evidence from other forms of school choice is also consistent with this conclusion. Many questions remain unanswered, however, including whether vouchers have longer-run impacts on outcomes such as graduation rates, college enrollment, or even future wages, and whether vouchers might nevertheless provide a costneutral alternative to our current system of public education provision at the elementary and secondary school level.Fonte

Charter Schools: Hope or Hype
http://terrear.blogspot.com/2010/11/charter-schools-hope-or-hype.html
O Final do 1º capítulo, de um livro com um título estimulante:Finally, we conclude with an attempt to pull together the disparate empiricalfindings of the earlier chapters and view them through the lens of our organizingframework. We return to our central question: are charter schools, on the whole, abeneficial policy reform, or are the hope and the hype unjustified by the facts?

The impact of school choice and public policy on segregation: Evidence from Chile
http://terrear.blogspot.com/2010/11/impact-of-school-choice-and-public.html
School choice advocates argue that the introduction of vouchers can make improved educationalopportunity available to the most disadvantaged children. Critics contend that vouchers increase the risk of exacerbating inequities based on race and socioeconomic status. They are worried about whether disadvantaged parents have enough information to make good choices and whether parental preferences will lead families to select schools based on the race or class composition of their student bodies and not on their academic quality. Critics also fear that in order to remain competitive and save costs, private schools will have incentives to skim off the highest performing students who are usually least demanding in terms of resources. Most evidence in Chile confirms skeptics’ concerns. Researchers have found that Chile’s unrestricted flat per-pupil voucher program has lead to increased stratification across public and private schools. What has been overlooked, however, is segregation between schools within a sector and variation within private voucher forprofit and non-profit (religious and secular) school sectors. Using a highly detailed dataset, I examine public and private school segregation. I find that public schools are more likely to serve disadvantaged – low-income and indigenous – students than private voucher schools. I also find that the typical public school is more internally diverse with regard to ethnicity and socioeconomic status than the typical private voucher school. While differential behavior is also found across private school ownership types, the differences do not always comport with theory. The data suggest that school tuition is much more important than other factors in explaining segregation patterns between and within school sectors. I also find that policies that provide incentives for schools to enroll disadvantaged students can help to mitigate the stratifying effects of educational vouchers.Texto Integral

Escolha da Escola e Segregação
http://terrear.blogspot.com/2010/11/escolha-da-escola-e-segregacao.html
The economic debate around school choice is centered on two key questions. The proponents of school choice argue that the competitive forces released by school choice increase efficiency and make the schools more responsive to parents’ preferences. The resulting quality improvement benefits all students, including those not exercising choice themselves (e.g., Hoxby, 2003). The opponents argue that choice merely increases segregation. According to a typical argument, the students will be increasingly sorted according to family background or ability. This may hurt the most disadvantaged students who may become isolated in the worst schools (e.g., Fiske and Ladd, 2000.(...)The change in the admission system is only one of the important changes that affect segregation of students across schools. Segregation across residential areas has also increased. The increase in the private school sector also increases choice options and might lead to an increase in segregation across schools. However, the quantitative importance of these two changes appears to be small compared to the effects of the admission reform. This should not be very surprising. Changes in residential segregation are slow compared to sudden changes caused by the change in the admission system.Further, even though the private school sector has grown rapidly, it still represents a rather small fraction of students. For most students, the choice between different public schools is far more important than the choice between public and private schools.Texto IntegralEstudar para debater e escolher.
