Mayoral Control of Schools in Washington DC Appears to have Benefitted Children of College Grads, But Nobody Else

The reason given for having the office of the Mayor (originally Adrian Fenty) take over the school system in Washington DC, and abolishing all the powers of the elected school board, was to help the poorest kids.

But that’s not how it worked out, according to official test results from the National Assessment of Educational Progress.

Using those stats, harvested for me by the parent of a former student of mine from the NAEP database, we see that children in DC whose parents did NOT finish college made lower gains after 2007 (the date of the changeover) than they did before that date. However, children of college graduates in DC made higher gains after 2007.

Amazing.

And yet another sign that the education ‘reform’ movement is a complete failure.

Here are my graphs and raw data. (Right-click to see them enlarged, if you have a PC – not sure what to do if you have an Apple product.)

annualized gains pre and post mayoral control, DC, 8th grade math, by parental education

The vertical orange line shows the date (June of 2007) when Michelle Rhee was appointed as the first Chancellor of DC Public Schools. The black, dashed line represents average scale scores on the 8th grade math NAEP for students who reported that their parent(s) graduated from college, and the other lines shows scores for kids whose parent(s) did or did not graduate high school, had some college courses. The thin, double blue line represents those students who were unsure of their parental education.

I asked Excel to calculate the annual rate of change pre- and post-mayoral control, and you can see the results in the last two columns. The boxes filled in with yellow are the ‘winners’, so to speak. Note that for the period 2000-2007, the annualized change in NAEP scale scores on the 8th grade NAEP math test in DC is 2.63, which means that on the average, that group of students (yeah, it’s a different group of students for each testing event) saw their scores rise by 2.63 points per year, or 5.26 points every two years. However, for the period 2007-2017, after mayoral control, that same group of students saw their gains cut nearly in half – it tumbled to 1.41 points per year. Kids whose parents did graduate from high school (but went no further) and those whose parents had some education after high school, also saw their rates of increase tumble drastically. Kids who were unsure of their parental education levels or who didn’t report it also saw a drop, but not so large: dropping from 2.08 down to 1.88 points per year.

The only group which saw their annualized scores increase after mayoral control were the children of college graduates: their rate went from 1.16 points/year to 2.60 points per year, which to me looks rather significant.

Ironic, huh?

And here are the results for reading:

annualized gains pre and post mayoral control, dc, 8th grade reading, by parental education

Once again, the results for students whose parents did NOT graduate from college (the first three lines of the table) tumbled dramatically after mayoral control. However, students whose parents did graduate from college (the fourth line) saw a dramatic increase. The last line, representing kids who didn’t know or didn’t report their parental education, saw a little uptick after mayoral control.

Remind me again why  we got rid of the elected school board and put the mayor in charge? Was it really to make sure that the ‘haves’ would get more and that the ‘have-nots’ would have less?

Let me point out the obvious: white parents in DC are overwhelmingly college-educated. Those in DC who did not graduate from high school, or who graduated from 12th grade and went no further, are overwhelmingly African-American or Hispanic. So our ‘reforms’ have had a disproportionately negative impact on black and hispanic students, and a positive one on white kids.

Was that really the intent all along?
