A recent article in The Guardian caught my eye: “Report accuses government of increasing inequalities in developing countries by financing academies at the expense of state schools.” The report, conducted by the U.N. Committee on the Rights of the Child, was an attack on U.K. aid money being linked to private education providers since the rapid increase in such schools may be contributing to sub-standard education. In particular, they cited the U.K. government’s investments in the Nairobi-based and for-profit Bridge International Academies.

I’ve worked on private education extensively throughout my career and do not believe there is anything wrong with private schools, but in this particular case I couldn’t agree more. But to be clear, it’s the funding strategy that’s the problem.

Private schooling is on the rise in a number of poor countries, and Pakistan—where my education research is focused—is no exception. The majority of these schools are no longer the elite institutions of yore, but low-cost alternatives fighting for survival in a highly competitive environment. These schools have mushroomed in response to increased parental demand and poor public alternatives, but also to the greater availability of teachers in the local labor market.

More importantly, research increasingly demonstrates that there is absolutely nothing wrong with private schools. There's a summary of this research available here; specific examples on India (more here) and Pakistan are also available.

Some key are takeaways from this research are:

• Private schools charge low fees (about $1 to$2 a month in Pakistan).
• The quality is almost certainly higher compared to government schools in the vicinity.
• At least in Pakistan, there is no significant segregation between public and private schools in terms of parental wealth, education, or caste.
• The most significant barrier to attendance in low-cost private schools is not cost—it’s distance. Put simply, there just aren’t enough of them around.

If there is a cheaper and better alternative to public schooling, shouldn’t we encourage children to shift and thus improve the quality of education for all?

Perhaps. But when the rubber from these well-intentioned aid policies hits the road of rural Pakistan, Kenya, or Ethiopia, a very different sort of model emerges. Instead of supporting private schooling, donors end up supporting private schools (or at best private school chains), which is an entirely different action with little theoretical backing. In fact, economic theory screams that governments and donors should almost never do that.

Donors say the problem is that the low-cost private school market is fragmented with no central authority that can be “contracted with.” No one has a good model on how to work with a competitive schooling sector with multiple small players—ironically, the precise market structure that, according to economics, leads to efficiency.

In reality, I suspect the problem goes deeper. Most low-cost private school owners don’t do well at donor conferences. They don’t know how to tell compelling human-interest stories about the good they do. But what they are excellent at is using local resources to ensure that their schools meet the expectations of demanding parents.

The first is a problem of accountability. Public schools are accountable, through a democratic system, to citizens of the country. Private schools are accountable to the parents. And donor-funded private school chains are account to the donors. While both citizen-led accountability and direct accountability to parents have problems, they are grounded in centuries of experience. It’s unlikely that donors in a foreign land, some of whom can’t visit the schools they fund for security reasons, can do better than either citizens or parents.

The second is a problem of market structure. When one private school or private school chain receives preferential treatment and funding, without allowing other private schools to apply for the same funds, the donor is picking winners (remember Solyndra?). The need for private schools as an alternative to government schools is insufficient justification for donors to put their thumbs on the scale and tilt the balance of power towards a pre-identified entity.

In a recent experiment, my colleagues and I gathered direct proof for this assertion. We gave untied grants to low-cost private schools with a twist. In certain villages, we randomly selected a single private school for the grant. In others, we gave the grant to every private school in the village. Our preliminary results show that in villages where we gave the grant to a single school, the school benefitted enormously from an increase in enrollment. Where we gave the grant to multiple private schools, the enrollment increase was split among schools. But only in the villages where we gave the grant to every school did test-scores for children increase.

What happened? When a single private school receives the grant, knowing that the other schools cannot react due to a lack of funds, they engage in “customer poaching” to increase their profits at the expense of others. Some have argued that Uber’s recent fundraising is precisely such an effort to starve competitors of funding.

When you equally support all private schools, customer poaching does not work, and the only way to increase profits and generate returns is to increase the size of the market, either through higher overall enrollments or through new quality offerings.

The first strategy supports pre-identified private schools and concentrates market power. The second, by providing opportunities for all private schools, improves education for children.

Sure, some private school chains and schools are making positive impact and deserve the support they can get. But funding such schools creates the wrong institutional structures and are more likely to lead to disasters than successes (Greg Mortensen and 3 cups of tea, anyone?).

In general, the Government’s responsibility towards the education of children is two-fold:

• Alleviate the market constraints that hold back private schooling without favoring one school over the other—letting parents decide who succeeds and who does not.
• Support and improve public schools to provide an alternative because there will always be children who cannot enroll in private schools, either because they are too expensive or because they are too far away, or because they don’t offer the instruction “basket” that some parents want.

In short, foreign aid should play no part in supporting private schools rather than private schooling.

Donald Trump has made waves during this year’s election cycle by taking a hard line on illegal immigration. This, however, builds on years of heated debate among policymakers. It is also an enduring hot-button issue in Arizona, which has passed several immigration laws over the years.  In 2010, the passage of SB 1070 brought national attention to this debate.  Deemed the strictest immigration law to date, SB 1070 sought to achieve “attrition [of illegal immigrants] through enforcement” by requiring law enforcement to detain any person whom they believed to be residing in the country illegally. Although SB 1070’s effects on individuals and families have been well documented, little is known about its impact on students and schools. To this end, we sought to estimate the relationship between the passage of SB 1070 and school-level student achievement.

We anticipated that anti-immigration policies would primarily affect children from the families of undocumented immigrants. Such effects could be observed in different ways. For instance, the emotional and psychological distress of these children could result in a decline in average test scores at the school-level. On the other hand, students might have left the country or the state under the threat of being deported in which case school-level test scores would rise (since these students often perform below their peers). To this end, we considered three scenarios: 

1. Immigrant children remain in the state but experience higher levels of stress.  As a result, average school-level test scores will drop while Hispanic enrollment remains the same.
2. Children of undocumented immigrants leave the state, which results in a drop in Hispanic enrollment accompanied by an increase in school-level test scores.
3. Or, the first two scenarios occur simultaneously and we do not observe any change in test scores since the two effects would cancel each other, but note a slight decrease in Hispanic enrollment.

In order to see which of these hypothetical scenarios is supported by the data, we first estimated the relationship between the passage of SB 1070 and average school-level reading test scores. We then attempted to unpack the mechanism through which such an effect might have taken place. To this end, we used publicly available data on school-level achievement and enrollment collected by the Arizona Department of Education (ADE). Given the targeted nature of the policy and the demographics of immigrants in Arizona, the majority of whom are of Hispanic or Mexican descent, we focused on schools that traditionally enroll large proportions of Hispanic students. We identified schools with high (more than 75 percent) shares of Hispanic students as those whose average achievement and student composition are most likely to be affected by immigration reform. We contrasted changes in school-level achievement and enrollment in those schools with schools that enroll less than 25 percent Hispanic students, as these schools are less likely to experience any changes as a result of tightening immigration laws.

Figures 1 and 2 show trends in the average percentage of students passing the state reading test and average Hispanic enrollment at these schools between 2006-2007 and 2011-2012.           

Figure 1. Average Percent of Students Passing AIMS Reading

Figure 2. Average Hispanic Student Enrollment

Clearly, the rate of growth in school-level reading scores was much higher for high Hispanic schools after the passage of SB 1070 in 2010 (Figure 1). At the same time, there was a significant decrease in Hispanic enrollment in these schools (Figure 2). Thus, it appears the second scenario is likely driving the patterns we observe.

The data also suggest that the trends for high Hispanic and low Hispanic schools started diverging before the passage of SB 1070 - after the 2007-2008 school year.  This happens to be the year that Arizona passed an even more restrictive, though less controversial, immigration law – the Legal Arizona Workers Act (LAWA). LAWA required Arizona business owners to verify the legal status of their employees using E-Verify, an online tool managed by the federal government. Although LAWA used a different mechanism, similar to SB 1070 it sought to achieve the attrition of undocumented immigrants from the state. 

We then would anticipate both laws to have similar effects on school-level achievement and Hispanic enrollment. Indeed, we estimated that LAWA likely led to an average increase of roughly 4 percent of students passing the state reading test at high Hispanic schools. This was accompanied by an average loss of 38 Hispanic students per school. Because the passage of SB 1070 was preceded by the passage LAWA as well as a language policy that would have affected treatment schools, disentangling the effects of these two policies is not straightforward. However, based on our analysis, we estimate that SB 1070 is associated with an average increase of between 1.5 percent and 4.5 percent of students passing the state reading test at the school-level accompanied by an average loss of between 14 and 40 Hispanic students. 

Despite the fact that we cannot pin down the exact magnitude of SB 1070’s effect on school-level achievement, our analysis shows that when Arizona passed restrictive immigration laws in 2008 and 2010, it looked as if the state’s lowest performing schools were improving rapidly. This, however, likely had more to do with the changing composition of schools as an indirect though anticipated effect of immigration policies than with policies aimed at improving student achievement. 

Despite this, the Arizona Department of Education took credit for these gains. Similarly, Arizona was recently recognized as one of the nation’s leaders in growth on the National Assessment of Educational Progress (NAEP) over the last ten years. Although wrongly attributing these gains may seem harmless at first glance, it is important to remember that Arizona is viewed by many as a model for controversial education reforms like school choice and high-stakes accountability. It is easy to imagine how policymakers might look at increasing test scores in Arizona and wrongly attribute them to these kinds of reforms. That’s not to say that these policies don’t have merit. However, if other states adopt education policy reforms under the assumption that they worked in Arizona, then they might find that these policies fail to deliver.

INTRODUCTION

Economic inequality has been on the rise in America for more than three decades. The nation’s traditional engine for promoting equality and opportunity—its public education system—has been unable to halt that upward trend despite increased public spending at the preschool, K–12, and postsecondary levels. Meanwhile, accumulating research evidence reveals that postsecondary education has, for the past few decades, proved an increasingly powerful tool in boosting the income and economic mobility of disadvantaged students. Here we outline steps that high schools can take to increase the college readiness of poor and minority students, making it more likely that they will be accepted into and graduate from college.

The annual income difference between Americans with a college degree and those with a high school degree was more than $33,000 in 2007, up from $12,500 in 1965. More to the point, long-term intergenerational data from the Panel Study of Income Dynamics show that a college degree helps disadvantaged children move up the income distribution past peers in their own generation. Adult children with parents in the bottom fifth of income, for example, nearly quadruple (from 5 percent to 19 percent) their chance of moving all the way to the top fifth by earning a college degree.

But too few poor kids get a college degree. About one-third of all youngsters from the bottom fifth of family income enter college and only 11 percent get a degree. By contrast, 80 percent of those from the top fifth enter college and well over half earn a degree.

Perhaps the primary reason that poor and minority students do not enter and graduate from college is that they are poorly prepared to do well there. The problem is especially evident in the huge gap between the academic achievement of white, Asian, and middle- and upper-income students as compared with black, Hispanic, and low-income students. And decades of educational reform aimed at reducing this gap have had, at best, modest success. Striking evidence of how few college freshmen meet even the most basic college preparation standards is provided by Jay Greene and Greg Forster of the Manhattan Institute. Defining minimum college readiness as receiving a high school diploma, taking courses required by colleges for basic academic preparedness, and demonstrating basic literacy skills, Greene and Forster report that only around 40 percent of white and Asian students were college ready by these criteria. But that figure was twice the 20 percent rate for black students and more than twice the 16 percent rate for Hispanic students.

The latest issue of The Future of Children, devoted to exploring how to improve America’s high schools, contains several articles that touch on student preparation for postsecondary education and the world of work. An especially compelling article, written by Melissa Roderick, Jenny Nagaoka, and Vanessa Coca, of the Consortium on Chicago School Research at the University of Chicago, contains a careful analysis of how to measure whether students are ready for college and a host of proposals for actions high schools can take to increase their students’ readiness for postsecondary education. As the Roderick article and related research and analysis make clear, recent years have seen an upsurge of support for the goal of helping all students, but especially poor, urban, and minority students, prepare for college, enter college, and earn a terminal degree. Attaining that goal, we believe, would boost economic mobility in the United States and help the nation live up to its ideals of equality of educational and economic opportunity.

In her February 25 Brookings report, Dr. Dale Farran questions the scientific case for endorsing widespread policy in preschool education. Indeed, she argues that enthusiasm for public preschool and its promise is “premature.” Her argument is founded on three points—that the data on impact is mixed, that we do not have scientific direction with respect to the key quality constructs, and that our measurement of these constructs lack empirical validity. There is a grain of truth in each of these statements. Yet, a closer look reveals that when the data are focused on high quality preschools, the weight of the evidence for effectiveness is compelling. The early childhood science is at least evidence informed on the skill sets that will promote later school and life success and valid measures exist for many of the important outcomes. While there is always more to be learned, the bulk of the scientific community contends that high quality preschool programs will play a role in preparing young children for success in school and beyond.

There is no doubt that the literature looking for relationships between preschool access and school readiness outcomes in literacy, mathematics, and other domains are mixed.  Both the Head Start Impact Study and recent findings from Farran’s own Tennessee pre-k study (Lipsey et al., 2015) indicate that preschool of less than high quality produce only modest short-term gains. 

The data do not look bleak, however, when we look across preschool outcomes in the aggregate. And when high quality programs are investigated, whether in well-controlled studies of intensive models (e.g., Perry and Abecedarian) or in studies of strong public programs in Boston (Weiland & Yoshikawa, 2013), Cincinnati (Karoly & Auger, 2016), New Jersey (Barnett et al., 2013), North Carolina (Peisner-Feinberg et al., 2015), and Tulsa (Hill et al., 2015), the results are downright promising  (Yoshikawa et al., 2013; Minervino. 2014). Society reaps benefits from fostering early skill development, as children participating in high quality preschool programs had lower rates of grade retention, less need for special education, decreased antisocial behavior, and greater productivity as adults (Reynolds & Temple, 2015; Cunha & Heckman, 2006). In 2014, over 1,200 scientists who work in the area of early education signed the ECE Consensus Letter for Researchers, attesting to the mountains of data in support of the role of preschool education in improving child outcomes in social development, language, pre-literacy, and mathematics.

Though Farran’s brief reviews only data from the United States, a growing literature suggests that preschool education has long and lasting and causal effects on outcomes around the globe (Atinc & Gustafsson-Wright, 2013). For example, an impact evaluation of a preschool program in Mozambique found that the program increased on-time enrollment into primary school among beneficiaries by 22 percent relative to the children in the control group. Enrolled children also experienced a 6 percent increase in fine motor development, and an 87 percent increase in cognitive development. More importantly, this is not just a story of “everything is bleak in the developing world so the program is bound to have an impact.”

With compelling data in the United States and across the globe, one might ask why there is such a great divide between Farran’s interpretation and that of the wider academic community? One reason appears to be that Farran discounts any data that did not emerge from random assignment longitudinal studies. While correlational studies are not the gold standard, they are informative. Surely practitioners and policymakers would not dismiss data on parenting practices because children were not randomly assigned to parents. Further, in the area of preschool education, there is no difference in findings between randomized trials and other methodologies with respect to targeted cognitive, achievement-related outcomes when other study and program features are taken into account (Duncan & Magnuson, 2013; Camilli et al., 2010). 

Farran also discounts many of the randomized trials because she says they do not tell us enough about cause and effect. She writes of the famous Abecedarian and Perry Preschool studies:

The primary difficulty with this approach as a basis for designing interventions is that there is no way to identify what specifically changed about children’s abilities that enabled them to perform better in school or to link those changes to any particular set of active ingredients in the treatment. Neither Perry nor Abecedarian explicitly describes beyond the broadest level the “treatment” that brought about their positive effects.

But the children did improve, and at some level—while it would be wonderful to isolate the exact recipe for preschool success—we need not deny children the benefits of preschool while scientists probe for the precise combinations of active ingredients that yield the best results. Consider an analogy: the impact of storybook reading on children. While numerous studies document that reading storybooks with children in a joint way improves vocabulary and early literacy, we have yet to isolate the exact causal factors that matter in book reading. Perhaps it is the cuddling that occurs between child and parent; perhaps this crucial unstudied variable is the key that has not yet been turned. But no one would argue that we should stop book reading as a way to foster young children’s interest in reading. So it is with preschool. A quality preschool can heighten young children’s desire to attend school and prepare them for learning—even if all the ingredients in the magic sauce have not yet been identified.

In short, the evidence does provide models of high quality preschool that effectively prepare children for entrée into school and that change a child’s trajectory toward success. Not knowing the exact mechanisms by which preschool exerts its impact is secondary to the fact that poor children need good preschools now and we know how to provide them.

Farran raises the very important point that a narrow focus on only reading and math outcomes would be misplaced in our quest to build high quality preschool curricula. We could not agree more. She goes on to write, however, that “premature as well is the presumption that solid research exists to guide the content and structure of pre-K programs.”

Here we beg to differ. There are thousands of studies that speak to the skill sets children need to achieve success in the changing world. Reading and math are among these skills—collectively bundled under what Golinkoff and Hirsh-Pasek (2016) call “content skills.” But there is overwhelming evidence that children need to master skills that move beyond just reading and math. Content knowledge has, at its base, language and executive function skills. Language is the medium of instruction and executive function skills empower children with the ability to control their impulses and attend. Flexibility and working memory (Galinsky, 2010; Blair, 2016), also part of executive function, enable children to shift gears and remember what they have been told. But even language and executive function are not enough. Children must be prepared to participate alongside others (collaboration), to question when they are unclear (critical thinking) (Kuhn, 1999), and to have the persistence needed to stick with difficult problems—grit (Duckworth et al., 2007). These skills have been tested, are predictive of later achievement, have been shown to be malleable and to relate to academic, social, and learning outcomes in school.

Farran argues that we cannot provide high quality preschool because we lack strong measures of quality. Again, there is some truth in her assertion, but it seems to us somewhat confused. Farran mixes together policy benchmarks, measures of classroom practice, and child outcome measures. All are useful, but for different purposes. The first is meant to set a floor across many domains including health and safety. The second is designed for providing feedback on classroom practice. The last allows us to assess children’s wellbeing and progress. Well-designed continuous improvement systems for pre-K have detailed standards for learning and teaching that align with assessments of classroom practice and systems operation as well as with child assessments. Together with program standards these can provide a clear vision of high quality. They set high expectations for children’s learning and development and for pedagogy. Our ability to specify all of this exceeds our ability to measure it with reasonable investments of time and money. Nevertheless, classroom observation measures and child assessments as elements of a continuous improvement system help inform teachers and administrators about where they are and what steps they need to take next (Hall et al., 2012; Sylva et al., 2006; Williford et al., 2013). None of us would argue that this is easy, or that any single measure of classroom quality or child development is sufficient. Providing guidance for the improvement of learning and teaching is hard work and domain specific, but it is not futile.

Farran closes her report by suggesting that “[the] proposition that expanding pre-K will improve later achievement for children from low-income families is premature.” Perhaps instead it is Farran’s prognosis that is overly pessimistic. Research to date indicates that sustained access to high quality preschool does alter the trajectory of low-income children who are otherwise not exposed to early math and to age-appropriate books. In several now classic studies, the effects of a quality preschool education has far reaching consequences linked to not only reading and math, but to fewer incarcerations, teen pregnancies, and higher employment well into adulthood. As economists have shown, high quality early learning programs save money for society—a finding that has been replicated in different programs across the globe—in the United States, Canada, the U.K., and Mozambique.

Do we need to know more about what constitutes high quality and how to harness this reliably? Absolutely. But science offers evidence-based and evidence-informed advice on what has worked and what should work when brought to scale. We have an obligation to use the best science to serve our struggling children. Recent surveys indicate that a majority of the American public—Republican and Democrat—agrees that all children deserve a chance to reach their fullest potential. Let the science progress and let us use what we know at this point in time to meet the promise that all children should have a fighting chance to succeed. Better to light a candle than curse the darkness.
