But the big issues arise when achievement gaps are viewed over time. This is the primary focus of the NJDOE statement (as well as NJ’s overall 2011 education reform agenda). The state presents a bunch of graphs illustrating the trend in gaps between 2005 and 2011. The accompanying text asserts that race- and income-based gaps as measured by the state’s tests have been persistent since 2005 (NAEP results support this characterization – for instance, the difference between students eligible and not eligible for free/reduced-price lunch in 2011 is not statistically different from that in 2005 in any of the four main assessments).**
Differences in performance between student subgroups are important, but the “narrowing of the achievement gap,” as a policy goal, also entails serious, well-known measurement problems, which can lead to misinterpretations. For example, as most people realize, the gap between two groups can narrow even if both decline in performance, so long as the higher-performing group decreases more rapidly. Similarly, an achievement gap can remain constant – and suggest policy failure – if the two groups attain strong, but similar, rates of improvement.
Put differently, trends in achievement gaps, by themselves, frequently hide as much as they reveal as far as the performance of the student subgroups they are comparing. These issues can only be addressed by , at the very least, decomposing the gaps and looking at each group separately. And that’s precisely the case in NJ.
The simple table below compares the change (between 2005 and 2011) in average NAEP scale scores for NJ students who are eligible for free/reduced-price lunch (lower-income) versus those who are not eligible (higher-income). I want to quickly note that these data are cross-sectional, and might therefore conceal differences in the cohorts of students taking the test, even when broken down by subgroups.***This table shows that, in three out of four NAEP tests, both low- and higher-income cohorts’ scores have increased substantially, at roughly similar rates. In fourth grade math, students eligible for free/reduced-price lunch scored six points higher in 2011 compared with 2005, the equivalent of roughly half a “year of learning,” compared with a similar, statistically discernible five point increase among non-eligible students. The results for eighth grade math and fourth grade reading are more noteworthy – on both tests, eligible students in NJ scored 12 points higher in 2011 than in 2005, while the 2011 cohorts of non-eligible students were higher by roughly similar margins.
In other words, achievement gaps in NJ didn’t narrow during these years because both the eligible and non-eligible cohorts scored higher in 2011 versus 2005. Viewed in isolation, the persistence of the resulting gaps might seem like a policy failure. But, while nobody can be satisfied with these differences and addressing them must be a focus going forward, the stability of the gaps actually masks notable success among both groups of students (at least to the degree that these changes reflect “real” progress rather than compositional changes).
Only in eighth grade reading was there a discrepancy between subgroups –the score for the 2011 cohort of FRLP-eligible students is statistically indistinguishable from that of the 2005 cohort. This means that, by social science conventions, we cannot dismiss the possibility that the former change was really just random noise. So, to the degree that there was a widening of the NJ achievement gap in eighth grade reading between 2005 and 2011 (and, as stated above, it also wasn’t large enough to be statistically significant), it’s because there was a discernible change for one subgroup but not the other. This exception is something worth looking into, and it is only revealed when both groups are viewed in terms of their absolute, not relative scores.
Similarly, if one looks exclusively at achievement gap trends in a simplistic manner, the substantial increases between cohorts in seven out of eight subgroup/exam combinations would be ignored, as would the fact (not shown in the table) that both eligible and non-eligible students score significantly higher than their counterparts nationally on all four assessments.
Roughly identical results are obtained for the subgroup changes if the achievement gap is defined in terms of race – there were equally large increases among both white and African-American cohorts between 2005 and 2011 in all four tests except eighth grade reading, where the change between African-American student cohorts was positive but not statistically significant.
(One important note about the interpretation of these data: The cohort changes among seven of the eight groups shown in the table [or the gaps in any given year], assuming that some of it is “real progress,” should not necessarily be entirely chalked up to the success of NJ schools per se. This represents the rather common error of conflating student and school performance. That is, assuming that students’ testing results [and changes therein] are entirely due to schools’ performance – though it’s well-established empirically that this is not the case. Some of the change is school-related, while some of it is a function of non-school factors [and/or sampling variation]. Without multivariate analysis using longitudinal data, it’s very difficult to tease out the proportion attributable to instructional quality.)
Nevertheless, the simple data above do suggest that an overintepretation of the achievement gap as an educational measure, without, at the very least, attention to the performance of constituent subgroups, can be problematic. Yes, in any given year, the differences between groups can serve as a useful gauge of inequality in outcomes, and, without question, we should endeavor to narrow these gaps going forward, while hopefully also boosting the achievement of all groups.
But it’s important to remember that the gaps by themselves, especially viewed over time, often mask as much important information as they reveal about the performance of each group, within and between states and districts, as well as the ways in which the actual quality of schools interact with them. Their significance can only be judged in context. States and districts must interpret gaps in a nuanced, multidimensional manner, lest they risk making policy decisions that could actually impede progress among the very students they most wish to support.

* It’s also worth noting that the achievement gap as defined above – the difference in scores between students eligible and not eligible for free/reduced-price lunch – is not statistically different from the U.S. public school student average in three out of four NAEP tests (with the exception being eighth grade reading, where the NJ gap is moderately larger).
** Most of the data presented in the NJDOE statement are achievement gaps on the state’s tests, as defined in terms of proficiency rates – that is, the difference in the overall proficiency rate between subgroups, such as students who are and are not eligible for free/reduced-price lunch. Using proficiency rates in serious policy analysis is almost always poor practice – they only tell you how many students are above or below a particular (and sometimes arbitrary) level of testing performance. However, measuring achievement gaps using these rates, especially over time, is almost certain to be misleading– an odd decision that one would not expect of a large state education agency. In this post, I use actual scale scores.
*** Since most achievement gaps compare two groups of students, they often mask huge underlying variation. For example, the comparison of students who are eligible versus those not eligible for free- and reduced-price lunches completely ignores the fact that this poverty measure only looks at students below a certain threshold, thus concealing the fact that some students below that line are much more impoverished than others, making comparisons between states and districts (and over time) extremely difficult (making things worse, income is a very limited measure of student background). On a related note, one infrequently-used but potentially informative conceptualization of the achievement gap is the difference between and high- and low-performing students (e.g., comparisons of scores between percentiles).
ahhh, the memories…
When most people think of the roughly $150 billion in federal stimulus money put toward education, they think of the jobs it saved.
A lesser-known component of the American Recovery Act allocated $5 billion for turnaround efforts at the 5,000 worst schools in America.
As explained in a three-part series by The Denver Post’s Jennifer Brown last week, that portion of the stimulus had a jobs component (even if unintentional) as well: rewarding consultants with roughly $1 billion.
Unfortunately, as Brown’s stories pointed out, too little energy has gone into tracking how the money was spent or measuring whether it served its intended purpose.
“There is not $1 billion worth of good consultants; there aren’t enough good consultants in the country,” Van Schoales, chief executive of the education advocacy group A+ Denver said.
And, because no one is gathering nationwide data on the three-year endeavor, educators (and taxpayers) will have a harder time rating the various providers and replicating those efforts that show promise.
On the bright side, Colorado is one of 15 states that had the foresight to track where and how the money was spent. So we know that $9.4 million of the $26.6 million (33 percent) delivered by the Education Department to Colorado schools in the last two years went to consultants.
On average, Brown discovered that in the 15 states that are tracking the money, $25 out of every $100 went to the consultants.
For their efforts, those states will have a better sense of what worked, and what didn’t, than others.
Already, the Colorado data are showing schools where considerable money has been spent where outcomes are not improving. That’s concerning, and it bears watching as the final year of grants are handed out.
Diane Ravitch, a former U.S. secretary of education, called the program “a bonanza for entrepreneurs and testing companies.”
But what about the children the money was supposed to help?
These schools are the nation’s worst, with low graduation rates and unacceptable student achievement.
As educators, lawmakers and taxpayers look back on this $5 billion rescue effort, we fear they will learn the real benefactors in the rushed attempt at education reform were private contractors who flocked to the scene rather than the students whose futures depended on it.

My Comments in RED.
When students came back to Glasgow High School last fall, hopes were high that the low-performing school would start to show great progress. Designated to participate in the state’s “Partnership Zone” school program, a three-year, public-private effort funded by federal Race to the Top grants, Glasgow totally restructured its operation. It created four “academies” of learning within the school, increased parent involvement, and extended the school day, using staggered start times for staff. Later in the year, teachers planned to start “Project Based Learning” — breaking common core learning standards into 4- to 6-week chunks of curriculum, culminating in a comprehensive project for students. The reform effort didn’t go exactly as planned. “We had a rough start to the school year and we’ve hit some bumps along the way,” said Glasgow principal Sherry Gross. But recent student test scores showed a noticeable jump from earlier in the year. “I think we’re finally starting to gain some momentum,” Gross said, though one critic (yes, I am once again the critic shedding light onto the dark side of the PZ. Growth is fine and dandy, but we continue to fail children at GHS and it’s not the teachers, it’s the plan. Proficiency rates are woefully below any semblance of where our parents, students and taxpayers want them to be and we need to be accountable to them. As you listen to our board meetings I have consistently been the most consistent questioner of scores, metrics and tactics) noted Glasgow students are still a long way from meeting proficiency goals. Glasgow’s experience shows some of the challenges in turning around a low-performing school. Teachers were enthusiastic at first (why aren’t they now? Teacher morale is function of many things and those who read my blog regularly know what numnber one is), as they prepared to revamp the way the school would operate. “In the summer there was a lot of synergy and a lot of energy toward, ‘we can do this,’ ‘this is good stuff,’ said Gross, who took on the principal’s job in August, not long before school started. But some of the staff who signed up to be part of the partnership zone school “didn’t really realize what they were getting themselves into and really questioned whether or not this is something for them,” How could that be? They were selected based on a state approved teacher selection process that the DDOE froze out 11 Million dollars to protect? she said. When those questions were answered, half of the staff left Glasgow. Fortunately, being a Partnership Zone school allowed the positions to be filled quickly as professional development ramped up in late summer. “Then as the school year started and the kids walk in the building, after a few weeks of the staggered start time and the gaps where we had overloaded classes and not enough teachers to teach 1,200 students and only half the staff here at the end of the day, the front end of the day, you know people got worn down very quickly,” Gross said. The plan to stagger staff start times was abandoned in October when administrators found themselves short-handed in the building.

Opinion in “The News Journal” Scapegoats Charter Schools
Last week, The News Journal posted an opinion that opined the fact that our schools have become more segregated due to charter schools and school choice options – while failing to acknowledge the basic rules of our education system that lead to this problem in the first place.
First, let’s put to rest the debate that school choice is beneficial. Consider Delaware’s non-public school options, which enrolled over 15 percent of total students during the 2010-2011 school year – not to mention the much larger system of school choice embedded in our real estate market. These options, readily available to many middle-to-high income families, are, by definition, school choice since they vote with either their wallet or their mortgage. Lower-income families, unfortunately, don’t have that luxury. Without these options, they are left to send their children to their district feeder school, regardless of its performance – bringing us to the purpose of (some) charter schools and school choice, which is to level the educational playing field by giving parents access to the free market that they can’t afford on their own. Until we tackle issues of funding and governance (along with others, such as development), segregation along income, and presumably race, lines is here to stay, with charters and school choice as the most viable, albeit imperfect, option we have.
Second, the opinion claims that charters are de facto segregation. Analyzing at the data reveals what is demonstrated in the above paragraph, which is that district schools (not just charter) are negatively impacted by this reality. For example, Warner, Stubbs, and Harlan Elementary schools, all from different districts and located within the city of Wilmington, have low-income and minority populations whose percentages far outnumber both district/state student populations and that of Delaware as a whole. Therefore, students that attend these schools aren’t segregated because of charters or choice; rather, they experience segregation in spite of these options. And while the author argues that charters and choice allow districts to avoid the tough decisions to combat this reality and its effects, the opposite is actually true in practice – only when forced, either by poor performance or decreasing enrollment/income, have we seen movement, although relatively weak, to improve opportunities for these kids.
Third, this conversation ties in to the broader movement to more accurately measure the school and teacher-level impact on student learning. While it’s no doubt true that more affluent kids disproportionally benefit from enriching environments outside the classroom, that doesn’t relieve us of our responsibility to assess the impact our precious tax dollars have on all students’ learning. This is at the heart of Common Core’s promise to provide a clear road map and end goal towards college and career readiness. And, more importantly, it’s the lynchpin of our state’s move towards a more growth oriented measurement of student success. These efforts, in the end, might yield results that surprise us all – helping all parents, regardless of zip code, determine which schools/teachers push their kids further, and faster, rather than across a specific cut-off point (proficiency at the end of the year).
Fourth, the author states that choice has led to overcrowding in some schools and vacant rooms in others. While that could be true, one could argue that districts and the Department haven’t exhausted all means necessary to identify building vacancies – many of which the nation’s highest performing charters would happily use and be held accountable to produce the results the author covets.
Unless we’re willing to tackle issues of funding and governance, we must work within the constraints of our system by taking a multi-pronged approach to both increase the availability and impact of charters and choice options while promoting best practices within our district schools – especially those from low-income and minority backgrounds that can’t access these on their own.

Today, I am heartened to have received multiple e-mails, and phone messages detailing both direct and indirect expressions of praise and excitement for the selection of Dr. Freeman Williams to guide the Christina School District. I am especially elated to note that more than one message was from the Delaware Department of Education, not an official message, but just a heartfelt expression of appreciation for the selection and a sentiment that the state DOE is excited, supportive, and ready to work with Dr. Williams when he assumes his post in July. A very nice day indeed.
Motion read into the record by John Young:
I believe that we are blessed to have an administrator in Christina who has dedicated almost his entire career to the students, teachers, staff and parents of Christina. He has worked for us in many and varied roles and has brought an earnest and sincere problem solving, collaborative approach to how he does his job. He has earned several promotions within our district and demonstrated a passionate, robust, meaningful and above all local approach to making his assigned areas both accountable and accessible. He has earned the respect of his coworkers, schools, fellow leaders and this board of education. It is time, in my opinion, for this administrator to take the next step in his career journey and assume day to day control and administration of our district and to fight for all of our children alongside our Board and to help craft the vision and future successes of our district moving forward.
I hereby move that the CSD BOE appoint Dr. Freeman Williams to the position of Superintendent of Schools for Christina, effective July 1, 2012 pending successful contract negotiations which may commence in the immediate future upon approval of this motion.
Board approved 7-0.
