Charter Schools And Teacher Diversity

A new study of North Carolina public schools finds that black students in charter schools are more likely to have black teachers than their regular public school counterparts, and that the positive effect of “teacher/student racial match” on the test scores of black students is more pronounced in charter than in regular public schools.

Like most good analyses of charter and regular public schools, this report, written by economist Seth Gershenson and published by the Fordham Institute, is an opportunity to learn from the comparison between the charter and regular public school sectors. For instance, the fact that the “match effect,” which is fairly well-established in the literature (e.g., Dee 2005), is stronger in charter schools is fascinating, though a well-informed discussion of the reasons why this may be the case is well outside of my rather modest wheelhouse (there are some possibilities mentioned in the paper’s conclusion). 

I’d actually like to focus briefly on the first finding – that teacher/student racial match is more common for black charter school students. This is the descriptive and arguably less interesting part of the analysis, but it struck me because, like the paper's main finding about the magnitude of the "match effect," it too raises policy-relevant questions, in this case about why teacher diversity might vary between sectors.

The Offline Implications Of The Research About Online Charter Schools

It’s rare to find an educational intervention with as unambiguous a research track record as online charter schools. Now, to be clear, it’s not a large body of research by any stretch, its conclusions may change in time, and the online charter sub-sector remains relatively small and concentrated in a few states. For now, though, the results seem incredibly bad (Zimmer et al. 2009; Woodworth et al. 2015). In virtually every state where these schools have been studied, across virtually all student subgroups, and in both reading and math, the estimated impact of online charter schools on student testing performance is negative and large in magnitude.

Predictably, and not without justification, those who oppose charter schools in general are particularly vehement when it comes to online charter schools – they should, according to many of these folks, be closed down, even outlawed. Charter school supporters, on the other hand, tend to acknowledge the negative results (to their credit) but make less drastic suggestions, such as greater oversight, including selective closure, and stricter authorizing practices.

Regardless of your opinion on what to do about online charter schools’ poor (test-based) results, they are truly an interesting phenomenon for a few reasons.

Charter Schools And Longer Term Student Outcomes

An important article in the Journal of Policy Analysis and Management presents results from one of the published analyses to look at the long term impact of attending charter schools.

The authors, Kevin Booker, Tim Sass, Brian Gill, and Ron Zimmer, replicate part of their earlier analysis of charter schools in Florida and Chicago (Booker et al. 2011), which found that students attending charter high schools had a substantially higher chance of graduation and college enrollment (relative to students that attended charter middle schools but regular public high schools). For this more recent paper, they extend the previous analysis, including the addition of two very important, longer term outcomes – college persistence and labor market earnings.

The limitations of test scores, the current coin of the realm, are well known; similarly, outcomes such as graduation may fail to capture meaningful skills. This paper is among the first to extend the charter school effects literature, which has long relied almost exclusively on test scores, into the longer term postsecondary and even adulthood realms, representing a huge step forward for this body of evidence. It is a development that is likely to become more and more common, as longitudinal data hopefully become available from other locations. And this particular paper, in addition to its obvious importance for the charter school literature, also carries some implications regarding the use of test-based outcomes in education policy evaluation.

Student Attrition And "Backfilling" At Success Academy Charter Schools: What Student Enrollment Patterns Tell Us

This is the second of two posts on Success Academy Charter Schools. The first post was entitled “Student Discipline, Race and Eva Moskowitz’s Success Academy Charter Schools.”

Last fall, at a press conference called to respond to a New York Times exposé of efforts to “push out” targeted students from New York City’s Success Academy Charter Schools, Eva Moskowitz , the charter chain’s founder and CEO, described those practices as “an anomaly.”

“Our goal in suspending children or issuing any consequences,” Moskowitz told reporters, “is not to get rid of children or to have them leave our school. It is to have them have high standards of conduct.”

Last week, at a press conference called to respond to the New York Times publication of a video of a Success Academy model teacher berating a child for making a mistake in arithmetic, Moskowitz reiterated her claim that such practices were “anomalies.”

The notion that students were being “pushed out” in order to boost Success Academy scores on standardized exams was “just crazy talk,” Moskowitz told journalist John Merrow in a PBS interview.

Does the available evidence support Moskowitz’s claims? In search of an answer, I examined the student enrollment patterns at Success Academy Charter Schools, using the data currently available in the New York State Education Department’s school report cards.

Student Discipline, Race And Eva Moskowitz’s Success Academy Charter Schools

At a recent press conference, Success Academy Charter Schools CEO Eva Moskowitz addressed the issue of student discipline. “It is horrifying,” she told reporters, that critics of her charter schools’ high suspension rates don’t realize “that five-year-olds do some pretty violent things.” Moskowitz then pivoted to her displeasure with student discipline in New York City (NYC) public schools, asserting that disorder and disrespect have become rampant.

This is not the first time Moskowitz has taken aim at the city’s student discipline policies. Last spring, she used the editorial pages of the Wall Street Journal to criticize the efforts of Mayor Bill De Blasio and the NYC Department of Education to reform the student code of conduct and schools’ disciplinary procedures. Indeed, caustic commentary on student behavior and public school policy has become something of a trademark for Moskowitz.

The National Move to Reform Student Discipline Practices

To understand why, it is important to provide some context. The New York City public school policies that Moskowitz derides are part of a national reform effort, inspired by a body of research showing that overly punitive disciplinary policies are ineffective and discriminatory. Based on this research evidence, the American Academy of Pediatrics, the American Psychological Association and School Discipline Consensus Project of the Council of State Governments have all gone on record on the harmful effects of employing such policies. The U.S. Education Department, the U.S. Justice Department, civil rights and civil liberties organizations, consortia of researchers, national foundations, and the Dignity in Schools advocacy coalition have all examined the state of student discipline in America’s schools in light of this research.1

Recent Evidence On The New Orleans School Reforms

A new study of New Orleans (NOLA) schools since Katrina, published by the Education Research Alliance (ERA), has caused a predictable stir in education circles (the results are discussed in broader strokes in this EdNext article, while the full paper is forthcoming). The study’s authors, Doug Harris and Matthew Larsen, compare testing outcomes before and after the hurricanes that hit the Gulf Coast in 2005, in districts that were affected by those storms. The basic idea, put simply, is to compare NOLA schools to those in other storm-affected districts, in order to assess the general impact of the drastic educational change undertaken in NOLA, using the other schools/districts as a kind of control group.

The results, in brief, indicate that: 1) aggregate testing results after the storms rose more quickly in NOLA vis-à-vis the comparison districts, with the difference in 2012 being equivalent to roughly 15 percentile points ; 2) there was, however, little discernible difference in the trajectories of NOLA students who returned after the storm and their peers in other storm-affected districts (though this latter group could only be followed for a short period, all of which occurred during these cohorts' middle school years). Harris and Larsen also address potential confounding factors, including population change and trauma, finding little or no evidence that these factors generate bias in their results.

The response to this study included the typical of mix of thoughtful, measured commentary and reactionary advocacy (from both “sides”). And, at this point, so much has been said and written about the study, and about New Orleans schools in general, that I am hesitant to join the chorus (I would recommend in particular this op-ed by Doug Harris, as well as his presentation at our recent event on New Orleans).

Teacher Turnover At Success Academy Charter Schools

A recent New York Times article about the Success Academies, a large chain of New York City charter schools, focuses a great deal on the long working hours and heavy stress faced by teachers at these schools. The article reports that three Success Academy (SA) schools had teacher turnover rates above 50 percent. Officials from the network, however, dispute these figures, which they say are inflated by the fact that many teachers who leave SA schools simply transfer to other SA schools (i.e., they are counted falsely as leaving SA when they are in fact staying within the network).

In fact, SA officials claim that, when one account for these intra-network transfers, their true turnover rate across all their schools ("attrition from the network," in the article) between June 2013 and June 2014 was 17 percent, which is far lower than many critics suggest. Now, on the one hand, these ongoing debates about teacher turnover at SA schools, which have been occurring regularly for years, are a little strange. It is clear that SA teachers work unusually long hours in high stress, tightly regulated environments, and do so for salaries that are lower than those offered by most other professional jobs with similar working conditions. It is, therefore, hardly surprising that turnover would be high; indeed, high teacher churn, like student mobility, is in many respects part of the model of schools such as the Success Academies (and, of course, some turnover, such as that among poorly performing teachers or those who are not a good fit for their schools, can be beneficial).

On the other hand, however, SA officials are making an empirical claim about turnover at their schools, one that includes an interesting and somewhat unusual angle (intra-network mobility). And this claim is very easy to examine with teacher-level data that we happen to have available via a public records request. So, let’s take a quick look at turnover at SA between 2012-13 and 2013-14 (the latest year-to-year transition we have).

Charter Schools, Special Education Students, And Test-Based Accountability

Opponents often argue that charter schools tend to serve a disproportionately low number of special education students. And, while there may be exceptions and certainly a great deal of variation, that argument is essentially accurate. Regardless of why this is the case (and there is plenty of contentious debate about that), some charter school supporters have acknowledged that it may be a problem insofar as charters are viewed as a large scale alternative to regular public schools.

For example, Robin Lake, writing for the Center for Reinventing Public Education, takes issue with her fellow charter supporters who assert that “we cannot expect every school to be all things to every child.” She argues instead that schools, regardless of their governance structures, should never “send the soft message that kids with significant differences are not welcome,” or treat them as if “they are somebody else’s problem.” Rather, Ms. Lake calls upon charter school operators to take up the banner of serving the most vulnerable and challenging students and “work for systemic special education solutions.”

These are, needless to say, noble thoughts, with which many charter opponents and supporters can agree. Still, there is a somewhat more technocratic but perhaps more actionable issue lurking beneath the surface here: Put simply, until test-based accountability systems in the U.S. are redesigned such that they stop penalizing schools for the students they serve, rather than their effectiveness in serving those students, there will be a rather strong disincentive for charters to focus aggressively on serving special education students. Moreover, whatever accountability disadvantage may be faced by regular public schools that serve higher proportions of special education students pales in comparison with that faced by all schools, charter and regular public, located in higher-poverty areas. In this sense, then, addressing this problem is something that charter supporters and opponents should be doing together.

Lessons And Directions From The CREDO Urban Charter School Study

Last week, CREDO, a Stanford University research organization that focuses mostly on charter schools, released an analysis of the test-based effectiveness of charter schools in “urban areas” – that is, charters located in cities located within in 42 urban areas throughout 22 states. The math and reading testing data used in the analysis are from the 2006-07 to 2010-11 school years.

In short, the researchers find that, across all areas included, charters’ estimated impacts on test scores, vis-à-vis the regular public schools to which they are compared, are positive and statistically discernible. The magnitude of the overall estimated effect is somewhat modest in reading, and larger in math. In both cases, as always, results vary substantially by location, with very large and positive impacts in some places and negative impacts in others.

These “horse race” charter school studies are certainly worthwhile, and their findings have useful policy implications. In another sense, however, the public’s relentless focus on the “bottom line” of these analyses is tantamount to asking continually a question ("do charter schools boost test scores?") to which we already know the answer (some do, some do not). This approach is somewhat inconsistent with the whole idea of charter schools, and with harvesting what is their largest potential contribution to U.S. public education. But there are also a few more specific issues and findings in this report that merit a little bit of further discussion, and we’ll start with those.
