Progress (or Not) for DC’s 8th Graders on the Math NAEP?

8th grade naep math, DC, w + H + B

Here we have the average scale scores on the math NAEP for 8th grade students in Washington, DC.* You will notice that we don’t have data for 8th grade white students in DC in math for the years 2003, 2007, and 2009, because there weren’t enough white students taking the test in those years for the statisticians at NCES to be confident in their data.

The vertical, dashed, red line near the middle of the graph represents the date when the old, elected, DC school board was replaced by Chancellors Rhee, Henderson, and Wilson, directly appointed by the various mayors. That year (2007) was also when Rhee and her underlings instituted brand-new teacher evaluation systems like IMPACT and VAM and new curricula and testing regimes known as Common Core, PARCC, and so on. Hundreds, if not thousands, of teachers were either fired or resigned or took early retirement. If these reforms had been as successful as Rhee promised in writing, then the lines representing scores for white, black, and hispanic students in DC would go slanting strongly up and to the right after that 2007 change.

I don’t see it.

Do you?

In fact, let’s look carefully at the slopes of the lines pre-Rheeform and post-Rheeform.

For black 8th grade students, scores went from 231 to 245 in the years 2000 to 2007, or 14 points in 7 years, which is a  rise of 2.0 points per year. After mayoral control, the scores for black students went from 245 to 257, or 12 points in 10 years. That’s rise of 1.2 points per year.

Worse, not better.

For Hispanic students, scores went from 236 in the year 2000 to 251 in 2007, a rise of 15 points in 7 years, or a rise of about 2.1 points per year. After mayoral control, their scores went from 251 to 263 in 10 years, which is a rise of 1.2 points per year.

Again: Worse, not better.

With the white students, a lot of data is missing, but I’ll compare what we have. Their scores went from 300 in year 2000 to 317 in the year 2005, which is an increase of 3.4 points per year. After mayoral control, their scores went from 319 in 2011 to 323, in 2017 or a rise of four (4!) points in 6 years, which works out to about 0.6 points per year.

Once again, Worse, not better.

Voters, you have the power to stop this nonsense, if you get organized!

* Note that I’m using the numbers for Washington DC as a whole – which includes the regular DC Public School system, all the charter schools, as well as private (aka ‘independent’) and parochial schools. At one point, NAEP divided the DC scores into those for DCPS only (on the one hand) and for everybody else. In addition, they began to make it possible to separate out charter schools. However, since the regular public schools and the charter schools together educate the vast majority of students in DC, and the DCPS-only score-keeping started well after 2007, I decided to use the scores for all of DC because there was a much longer baseline of data, going back about twenty years.

  1. I just looked at the NAEP “difference from large cities” results for 4th grade math for DC and find:
    2003 -19
    2005 -16
    2007 -16
    2009 -11
    2013 -6
    2015 -2
    2017 -1

    I’m curious why the period you presented for the elected school board is so brief… Is it because it’s hard to get earlier data via the NAEP interface? I’d like to have been able to go further back with the above set of data, which seems to show startlingly good progress after mayoral control, but don’t immediately see how to do so.

  2. 1. Much of the data on these subgroups in 4th grade math was simply missing before 2000, so that’s why I stopped there,.They simply didn’t report it on the NAEP database. Feel free to search for yourself if you like.

    2. The Washington Post and DCPS administrators have already widely publicized that DC is no longer the worst city in the nation in terms of overall NAEP test scores (though they leave unsaid that it still has the widest gaps between whites and other groups). Detroit has apparently now fallen into last place in the league tables.
