In the past few posts, (**#1**, **#2**, **#3**) I’ve merely cut-and-pasted graphs or text that the *National Center for Educational Statistics (NCES*) published two days ago on their website as part of what has become a very widespread, longitudinal survey of statistics illustrating educational progress or problems in the large urban school systems of the USA; this one was called the NAEP TUDA.

The only modifications I did to the graphs were cutting out the ‘fine print’ that few of my readers would look at anyway, and adding some notations and color for clarity.

(BTW, if you want to look at the fine print, go right ahead! It’s all findable at that same website.)

This time, I actually lifted a few digital fingers and asked the NCES web site to produce some simple tables of longitudinal and cross-sectional data for DCPS and a few other cities. Nothing complicated: I just wanted to see how black, white, and Hispanic students have been faring, along with those in special education and immigrant kids learning English for the first time, compared with ‘regular’ kids, and compared with tbejr counterparts among alloother large public urban school systems. Then I had Excel plot the data. Here are my first two such graphs, exploring whether mayoral control of schools (and all that went along with that, such as eliminating tenure and turning education over to private corporations) helped or hurt.

I think the results are obvious.

Here goes:

Lots of information in this first graph, but you have to pay a little attention.

(1) Notice how high white students in DCPS score on this graph (solid red line, at the top). Those students, some of whose siblings I’ve taught at Alice Deal JHS/MS, are the highest-scoring subgroup that I know of in the entire NAEP/NCES/TUDA database. Overall, they continue to do well, and in the fourth grade, for math, the only departure from a straight-line trend was 2007. Their rate of growth in test scores exceeds that of white kids in all urban public school systems, probably because white kids in DC overwhelmingly come from professional, educated families. We don’t have any trailer parks or other sizable population of white working-class kids in DC, ever since the massive “white flight” of the 1960s. (You have to go elsewhere to find characters like those on “Honey Boo Boo”!) In any case, overall, no real change pre-Rhee to post-Rhee, other than the fact (not apparent in this graph) that the proportion of white students at most grades has vastly increased in DCPS: in a word, because of gentrification. In any case, white kids in DC continue to score a lot higher in 4^{th} grade NAEP math than white kids in other public urban school systems (dotted green line near the top).

(2) Among Hispanic students, it appears that the trends after 2008 in DCPS for fourth-grade math students aren’t so favorable to the pro-mayoral-control side of the argument: from 2003 through 2009, their scores were increasing at a pretty amazing rate (solid purple line) until they matched the scores of Hispanic students in all US urban school systems (dotted purple line). After that year, those scores went down or leveled off. Again, no miracle.

(3) Among black students at this grade level, if the trends for 2003-2007 had continued, the bottom orange line for black 4^{th}-graders in math would be a bit higher than it is now, largely because there was in fact no growth from 2009 to 2011.

(4) It’s a bit harder to see, but the hispanic-white and black-white achievement gaps at this grade level continues to be a lot larger in DC than it is in the nation’s urban school systems. Twice as wide, in fact. So, again, no sign of success.

Overall: no evidence here whatsoever of any of the promised miracles. In fact, if anything, growth was a little worse, overall, after Rhee, than it was before Rhee.

Now let’s look at achievement levels for 4^{th} grade math students with disabilities (ie special education), ELLs (English Language Learners) and those in regular education, both here in DC and in all US urban public school systems. Here, I chose to plot the percentages of students who are “Basic” or above, rather than the average scale score. You could plot scale scores yourself, if you like.

(A score of “Basic” on the NAEP corresponds to “Proficient” on the DC-CAS and other state-administered NCLB and RttT tests.)

Notice that most of these lines show an overall upward trend for this period. The top line (dotted, green) is the percent of all public-school, regular-education students in urban public school systems who score “Basic” or above on the fourth-grade math NAEP. The solid, maroon/brown line represents the same measurement for regular 4^{th}-grade math students here in DC. Notice that both the dotted green and solid brown lines are going up pretty steadily, with no particular change in trend on either side of the vertical orange line. Which means that mayoral control seems not to have changed to past trends one way or the other.

The olive-colored, dotted line represents percentages of fourth-grade students of English as a second language in all of our urban public schools. As you can see, the trend is a slow but steady increase. However, in DC public schools, since 2009, the corresponding line (solid, sky blue) is trending downwards. Why? I have no idea, but it’s not a favorable argument for continued mayoral control, since before Fenty and Rhee took over DCPS, the trend was certainly upwards.

With special education students, I used a dotted purple line for all national urban public school students, and a solid orange lines for those in DC public schools. I have no idea why the percentage of 4^{th}-grade math students scoring “Basic” or above went down across the nation’s cities after 2008, while it had been going up modestly but steadily before that date. Clearly, the trends in special-education scores in DCPS are even more mysterious: a continuation of past trends in 2009, a fairly large drop in 2011, and a fairly large increase in 2013. In any case, if you were to extrapolate the orange pre-Rhee line past the central line, I suspect you’d come to about the same place we are in right now (2013).

Again, this is evidence that all the churn, upheaval, anguish, money, and curriculum impoverishment of the past 6 years in the District of Columbia has all been for naught. We would have gotten the same results with the system we had in place beforehand.

## My conclusion: any progress in DCPS appears to be a continuation of trends that show up very clearly as going back ten years, well before the DC city council, with the blessing of Congress, abolished the school board and handed control of the public schools over to a chancellor appointed and responsible to a mayor.
