Most teachers will never meet a psychometrician, but every standardized test their students sit for went through one. Russell Ligon and Alexandra Lee do that work,, and in this replay hosts Ryan Lufkin and Melissa Loble ask them how they landed in a field almost nobody plans on, how assessment practice has shifted over their careers, and why the technical work behind a test decides whether it's fair to the student taking it.
In this episode:
- Failure gets treated as the thing assessment exists to prevent, and the group argues it teaches more than a clean score ever does.
- Accountability has moved from centralized to decentralized models, and with that came the expectation that a test be built against the standards of the state that adopted it rather than shipped intact from somewhere else.
- Psychometricians are the reason a test can be called equitable, and Russell and Alexandra walk through the parts of the job that never show up on a score report, including how each of them found their way into it.
- Assessment of learning, for learning, and as learning are three separate jobs, and a balanced system runs all three instead of asking one test to carry the whole picture.
- Every assessment spends time that instruction could have used, and the group is direct about that trade instead of treating more student data as free.
- Validity holds the whole structure up, because a test without it still measures something, just not what anyone needed to know, and a teacher who doesn't trust the instrument won't act on what it tells them.
- What comes next in assessment turns less on new technology than on whether the culture around testing lets a test show real growth, and the conversation closes on where AI fits into that.
