Is there any sense of causation here? Are there other variables at work here?

good question, chris --
i thought that it might just be a correlation, or something that SES would explain, but merryman (and the research she cites) suggests that it's causal, not obviously explained by SES, and takes place in a variety of circumstances. check it out -- let us know if it's missing something.

Did you post the wrong link? Not only do I not see any evidence of causation, I don't see any mention of NCLB.

hi, alexa --
the part about NCLB was a (bad) joke -- i was riffing off the thing people always say about how you can predict how many prison beds you need based on kids' test scores. sorry!

as for causation, i'll leave it up to you to decide whether the research is convincing.

thanks for reading -- let us know what you think.

Thanks Alexander, I was hoping that was tongue-in-cheek. I'll refrain from writing an overly snarky blog post about how correlation does not equal causation.

I've heard that "Prisons in Louisiana" line on 4 separate occasions now, from everybody from TFA to the New Teacher Project. I know you've linked to a blog post refuting it...I'm going to look for it now, because I read it a while ago and don't remember the particulars.

Thanks for posting the link though.

here's the link to the story that debunks the prisons-test scores myth:


feel free to write a snarky response about causation and correlation. all comments welcome.
