Plausible hypothesis; the outmigration numbers in the linked article do seem high. Even so, Chicago is big (denominator law!) and that’s a big jump. Would be nice to check.
Right after we get the highly anticipated GF Last Jedi review… 🙂
Thanks for reminding me! 🙄
Yeah- plus there is some odd stuff going on in the Chicago NAEP data. I’ll write an additional post soonish.
City level NAEP has always been a little dodgy. But a big swing like this has a cause somewhere.
Chicago’s reading results look similar, so something seems to be going on.
