[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]Interesting stats:

Charter sector is 79% African American and 82% economically disadvantaged
DCPS is 64% African American and 75% economically disadvantaged.

And also their parents are capable and willing to sign up for charter so not exactly the same population as those who just go to their neighborhood school now is it?  Motivation, parental involvement, small classes, etc are key!  I'm guessing by your horrible heading title that you knew that and were just trying to be provocative, I'm also guessing that you probably wrote the other posts. [/quote]

Yes, no way to rule out selection bias.  In other words, the more motivated, stable families could be the ones who have the wherewithal to apply for and attend charters (i.e., don't get sent back to their IB schools for infractions).  There's no way to say for sure otherwise unless families are randomized to either charter or non-charter public schools.  Of course, that can't be done, so there's really no way to say whether it's mainly the curricula/approaches of charters--or something pre-existing about the families who attend--that is responsible for the differences noted in scores.

I don't say this to knock charters--the self-selection of motivated, engaged families who attend is one of the reason charters were on our list.  However, I don't think we can attribute better scores solely to factors unique to charters without delving deeper.[/quote]

The two wards that had the highest participation rates in the common lottery were Ward 8 and Ward 7.https://ms-dc.s3.amazonaws.com/docs/2016-lottery-distribution-of-applications-by-war.pdf

I think the selection bias is less now that everyone must use the lottery for PK3 and PK4. All families care about location - nothing unique to poor families there - and commute time. A majority of families who are choosing charter schools are choosing ones near their homes but many do choose schools across the city - as the 'where students come from maps' bear out - especially as kids get older and are more able to commute independently.[/quote]
