Greetings From Due Diligence, New Jersey

Earlier this week, New Jersey Governor Chris Christie announced that the state will assume control over Camden City School District. Camden will be the fourth NJ district to undergo takeover, though this is the first time that the state will be removing control from an elected local school board, which will now serve in an advisory role (and have three additional members appointed by the Governor). Over the next few weeks, NJ officials will choose a new superintendent, and begin to revamp evaluations, curricula and other core policies.

Accompanying the announcement, the Governor’s office released a two-page "fact sheet," much of which is devoted to justifying this move to the public.

Before discussing it, let’s be clear about something - it may indeed be the case that Camden schools are so critically low-performing and/or dysfunctional as to warrant drastic intervention. Moreover, it's at least possible that state takeover is the appropriate type of intervention to help these schools improve (though the research on this latter score is, to be charitable, undeveloped).

That said, the "fact sheet" presents relatively little valid evidence regarding the academic performance of Camden schools. Given the sheer magnitude of any takeover decision, it is crucial for the state to demonstrate publicly that they have left no stone unturned by presenting a case that is as comprehensive and compelling as possible. However, the discrepancy between that high bar and NJ's evidence, at least that pertaining to academic outcomes, is more than a little disconcerting.

How Many Schools Don't Have Nurses?

In 2006, the National Association of School Nurses (NASN) commissioned the largest and, to my knowledge, most recent national survey on the availability of nursing services in U.S. public schools. It was administered to a sample of over 1,000 schools in all 50 states and D.C.

The primary purpose was to gather basic information on the health staff in these schools, as well as a few core characteristics, such as school size and student demographics.

I must confess that I was a little surprised by the results. Here is the distribution of schools by nursing availability, summarized very briefly (these proportions vary by school size, type and other characteristics):

The Ineffective Rating Fetish

In a story for Education Week, always reliable Stephen Sawchuk reports on what may be a trend in states’ first results from their new teacher evaluation systems: The ratings are skewed toward the top.

For example, the article notes that, in Michigan, Florida and Georgia, a high proportion of teachers (more than 90 percent) received one of the two top ratings (out of four or five). This has led to some grumbling among advocates and others, citing similarities between these results and those of the old systems, in which the vast majority of teachers were rated “satisfactory," and very few were found to be “unsatisfactory."

Differentiation is very important in teacher evaluations – it’s kind of the whole point. Thus, it’s a problem when ratings are too heavily concentrated toward one end of the distribution. However, as Aaron Pallas points out, these important conversations about evaluation results sometimes seem less focused on good measurement or even the spread of teachers across categories than on the narrower question of how many teachers end up with the lowest rating - i.e., how many teachers will be fired.

Poor Implementation Undermines Promise Of The Common Core

** Reprinted here in the Washington Post

Our guest author today is Stephen Lazar, a founding teacher at Harvest Collegiate High School in New York City, where he teaches Social Studies. A National Board certified teacher, he blogs at Outside the Cave. Stephen is also one of the organizers of Insightful Social Studies, a grass roots campaign of teachers to reform the newly proposed New York State Social Studies standards.

The Common Core Learning Standards (CCLS) seek to define “college and career readiness expectations." Forty-five states have adopted them, and are moving briskly towards full implementation in the coming year. Last January, I wrote that the standards “represent the greatest opportunity for history teaching and learning to be widely re-imagined since the Committee of Ten set the basic outlines for American education over a hundred years ago."

While I stand by that statement, with each step towards implementation I see the opportunity being squandered. We cannot possibly continue to move solely in the direction of “college and career readiness” in History & Social Studies education without ensuring that “civic” readiness is valued equally.  Additionally, we need to ensure that as states write new curricula, that they contain the proper balance of content, skills, and understandings.  New curricula will need to ensure students use an inquiry-based approach to go in depth with a smaller amount of content to gain the wider breadth of skills and dispositions required for civic, college, and career readiness.

A Controversial Consensus On KIPP Charter Schools

A recent Mathematica report on the performance of KIPP charter schools expands and elaborates on their prior analyses of these schools' (estimated) effects on average test scores and other outcomes (also here). These findings are important and interesting, and were covered extensively elsewhere.

As is usually the case with KIPP, the results stirred the full spectrum of reactions. To over-generalize a bit, critics sometimes seem unwilling to acknowledge that KIPP's results are real no matter how well-documented they might be, whereas some proponents are quick to use KIPP to proclaim a triumph for the charter movement, one that can justify the expansion of charter sectors nationwide.

Despite all this controversy, there may be more opportunity for agreement here than meets the eye. So, let’s try to lay out a few reasonable conclusions and see if we might find some of that common ground.

Causality Rules Everything Around Me

In a Slate article published last October, Daniel Engber bemoans the frequently shallow use of the classic warning that “correlation does not imply causation." Mr. Engber argues that the correlation/causation distinction has become so overused in online comments sections and other public fora as to hinder real debate. He also posits that correlation does not mean causation, but “it sure as hell provides a hint," and can “set us down the path toward thinking through the workings of reality."

Correlations are extremely useful, in fact essential, for guiding all kinds of inquiry. And Engber is no doubt correct that the argument is overused in public debates, often in lieu of more substantive comments. But let’s also be clear about something – careless causal inferences likely do more damage to the quality and substance of policy debates on any given day than the misuse of the correlation/causation argument does over the course of months or even years.

We see this in education constantly. For example, mayors and superintendents often claim credit for marginal increases in testing results that coincide with their holding office. The causal leaps here are pretty stunning.

Data Driving: At The Intersection Of Arbitrary And Meaningful

In his State of the City address last month, New York City Mayor Michael Bloomberg made some brief comments about the upcoming adoption of new assessments aligned with the Common Core State Standards (CCSS), including the following statement:

But no matter where the definition of proficiency is arbitrarily set on the new tests, I expect that our students’ progress will continue outpacing the rest of the State’s[,] the only meaningful measurement of progress we have.

On the surface, this may seem like just a little bit of healthy bravado. But there are a few things about this single sentence that struck me, and it also helps to illustrate an important point about the relationship between standards and testing results.

Teacher Surveys And Standardized Tests: Different Data, Similar Warning Labels

As a strong believer in paying attention to what teachers think about policy, I always review the results of MetLife’s annual teacher survey. The big theme of this year’s survey, as pushed by the press release and reiterated in most of the media coverage, was that job satisfaction among teachers is at “its lowest level in 25 years."

It turns out that changes in question wording over the years complicates straight comparisons of responses to the teacher job satisfaction over time. Even slight changes in wording can affect results, though it seems implausible that this one had a dramatic effect. In any case, it is instructive to take a look at the reactions to this finding. If I may generalize a bit here, one “camp” argued that the decline in teacher satisfaction is due to recent policy changes, such as eroding job protections, new evaluations, and the upcoming implementation of the Common Core. Another “camp” urged caution – they pointed out that not only is job satisfaction still rather high, but also that the decline among teachers can be found among many other groups of workers too, likely a result of the ongoing recession.

Although it is more than plausible that recent reforms are taking a toll on teacher morale, and this possibility merits attention, those urging caution, in my view, are correct. It’s simply not appropriate to draw strong conclusions as to what is causing this (or any other) trend in aggregate teacher attitudes, and it’s even more questionable to chalk it up to a reaction against specific policies, particularly during a time of economic hardship.

School Choice And Segregation In Charter And Regular Public Schools

A recent article in Reuters, one that received a great deal of attention, sheds light on practices that some charter schools are using essentially to screen students who apply for admission. These policies include requiring long and difficult applications, family interviews, parental contracts, and even demonstrations of past academic performance.

It remains unclear how common these practices might be in the grand scheme of things, but regardless of how frequently they occur, most of these tactics are terrible, perhaps even illegal, and should be stopped. At the same time, there are two side points to keep in mind when you hear about charges such as these, as well as the accusations (and denials) of charter exclusion and segregation that tend to follow.

The first is that some degree of (self-)sorting and segregation of students by abilities, interests and other characteristics is part of the deal in a choice-based system. The second point is that screening and segregation are most certainly not unique to charter/private schools, and one primary reason is that there is, in a sense, already a lot of choice among regular public schools.

Through The Sunshine State's Accountability Systems, Darkly

Some Florida officials are still having trouble understanding why they're finding no relationship between the grades schools receive and the evaluation ratings of teachers in those schools. For his part, new Florida education Commissioner Tony Bennett is also concerned. According to the article linked above, he acknowledges (to his credit) that the two measures are different, but is also considering "revis[ing] the models to get some fidelity between the two rankings."

This may be turning into a potentially risky situation. As discussed in a recent post, it is important to examine the results of the new teacher evaluations, but there is no reason one would expect to find a strong relationship between these ratings and the school grades, as they are in large part measuring different things (and imprecisely at that). The school grades are mostly (but not entirely) driven by how highly students score, whereas teacher evaluations are, to the degree possible, designed to be independent of these absolute performance levels. Florida cannot validate one system using the other.

However, as also mentioned in that post, this is not to say that there should be no relationship at all. For example, both systems include growth-oriented measures (albeit using very different approaches). In addition, schools with lower average performance levels sometimes have trouble recruiting and retaining good teachers. Due to these and other factors, the reasonable expectation is to find some association overall, just not one that's extremely strong. And that's basically what one finds, even using the same set of results upon which the claims that there is no relationship are based.
