As an introduction to a series I'm doing for What Happens in Texas about Texas schools, I started by researching a few facts and figures. In many cases, the data I discovered created more questions in my mind than answers, but I've decided that's a good thing. Research works that way; you're never sure where it's going to take you. I'm just going to put these here without a lot of explanation, and go swimming in the details later. I do want to call out the monkey wrench I threw in the last graph, which compares Texas per student spending to the US and to the averages of other developed countries, because I think this looks really interesting.
