Students in the boundary attend 81 schools, listed are Meridian, Mundo, Marie Reed, LAMB, Seaton, Cleveland, Hyde-Addison, Yu Ying, and Inspired Teaching.


In the 21-22 data, Garrison has 331 kids-- more than 10% enrollment growth in two years, wow! 138 are IB. There are 456 grade-specific kids living in the boundary (big drop!). So the school is 42% IB and the participation rate is 30%. So to me this spells improvement. Students living in the boundary attend 78 schools, listed are Meridian, Mundo Verde, Marie Reed, LAMB, and Seaton-- that's all.

The “improvement” is pure math. The participation rate “increased” 5% because the the number of kids living in bound decrease. Therefore if you reduced the denominator your result will be higher.

Ok but the enrollment growth is significant, no? And Garrison is turning away IB PKs now. Never used to be that way.

If you google for it you can get past years' data. https://dme.dc.gov/page/sy2019-20-public-school-enrollments-dcps-boundary

It's fascinating to compare. I will say, it's a bit of a project to keep in mind changes to feeder patterns, the unwinding of Education Campuses, and the impact of the 2014 re-boundarying. Some kids are attending the school that was their IB at the time they enrolled in it, and it's not their IB anymore but still that seems like an in-between category.

There are some DCPS schools that people really don't want to go to. Not just UMC people, either.

But you can’t ask this Q of this data set. It would be too difficult and expensive to get this data and of course, it wouldn’t be in CO’s best interests to find out so we will probably never know.

Also private schools don’t report this. They’re private, and have no requirement or need to report this info. At best you could merge with census type info on full population of students.

DME could require them to report it, but DME seems to have no interest.

As far I can tell roughly 10% of the kids in DC attend private school. In Ward 3 it's about 50%. There are pockets on Capitol Hill and Tacoma Park and almost none in the rest of the city.

+1 I will use these data every time a poster claims that most kids in their neighborhood attend their IB and no a charter school. Data > DCUM’s opinion

Yep. Clip and save for every time someone trots out “won’t send your kids to school with your neighbors.”

If you want to know how many IB attend the assigned school you need to look at Participation rate.

Participation rate: percent of public school students living in each school’s boundary who attend the school (the numerator is the number of in-boundary students enrolled at the school and the denominator is all grade-specific public school students living in the boundary)

Just to clarify though participation rate only includes those that participate in public school-- aka if you chose hardy or basis but live IB for deal -- This data does not include kids that live in bounds for Deal and go to private.

This mean that if they also includes kids that go to private then the participation rate will be even lower.

correct. A LOT lower for certain neighborhoods.

The fact that this info doesn't include private school makes it kind of uninteresting to me. I would LOVE a statistic on how many kids live in bounds for a school and opt for Private.

this is telling for me though -- 10-15% of kids ( more at the wealthy elementaries) that choose public for el school are leaving for private middle (or for the burbs) -- and if they haven't left by deal, another 10% will go by high school. I also wonder why there is so much controversy about keeping shepherd and bancroft in the JR pyramid when they have such a low in bounds rate...
