Earlier this spring, Education Next published an article by Paul T. von Hippel and Laura Bellows questioning whether it was possible to distinguish one teacher preparation program from another in terms of their contributions to student learning. Looking at data from six states, von Hippel and Bellows found that the vast majority of programs were virtually indistinguishable from each other, at least in terms of how well they prepare future teachers to boost student scores in math and reading.
Much of the national conversation around teacher preparation focuses on crafting minimum standards around who can become a teacher. States have imposed a variety of rules on candidates and the programs that seek to license them, with the goal of ensuring that all new teachers are ready to succeed on their first day in the classroom. Von Hippel and Bellows’ work challenges the very assumptions underlying these efforts. If states cannot tell preparation programs apart from one another, their rules are mere barriers for would-be candidates rather than meaningful markers of quality. Worse, if we can’t define which programs produce better teachers, we’re left in the dark about how to improve new teachers.
To probe deeper into these issues, we reached out to von Hippel, an associate professor at the University of Texas at Austin. What follows is an edited transcript of our conversation.
Bellwether: Can you start off by describing your work on teacher preparation? What compelled you to do the work, and what did you find?
von Hippel: It started with a 2010 contract that some colleagues and I at the University of Texas had with the Texas Education Agency. Our contract was to develop a pilot report card for the nearly 100 teacher preparation programs in the state of Texas. The idea was to come up with a teacher value-added model and then aggregate teacher value-added to the program level. We would then figure out which programs were producing better and worse teachers in the state, with the idea that the state would at a minimum provide feedback, encourage programs that were producing effective teachers and ideally expand them, and, in extreme cases, shut down programs that were producing a lot of ineffective teachers.
