Uncommon Denominators: Understanding “Per Pupil” Spending

April 30, 2014


This post is another in my series on data issues in education policy. The point of this post is to encourage readers of education policy research to pay closer attention to the fact that any measure of “per pupil spending” contains two parts – a measure of “spending” in the numerator and a measure of […]

On “Dropout Factories” & (Fraudulent) Graduation Rates in NJ

April 29, 2014


This NJ Star Ledger piece the other day reminded me of an issue I’ve been wanting to check out for some time now. I’m skeptical of graduation rates as a measure of student outcomes to begin with, because, of course, graduation can be strongly influenced by local norms and practices. As such, it’s really hard […]

As evidence of these inequities, […]

Why you can’t compare simple achievement gaps across states! So don’t!

April 16, 2014


Consider this post the second in my series of basic data issues in education policy analysis. This is a topic on which I’ve written numerous previous posts. In most previous posts I’ve focused specifically on the issue of problems with poverty measurement across contexts and how those problems lead to common misinterpretations of achievement gaps. […]

Understand your data & use it wisely! Tips for avoiding stupid mistakes with publicly available NJ data

My next few blog posts will return to a common theme on this blog – appropriate use of publicly available data sources. I figure it’s time to put some positive, instructive stuff out there. Some guidance for more casual users (and more reckless ones) of public data sources and for those must making their way […]
