A 50-year veteran of psychometrics — the science of measuring mental abilities and processes — offers a brief history and insights into the future of testing. Adaptive testing has been around since at least the early part of the 20th century. The goal has always been to measure something — such as IQ, academic progress or personality traits — with the same precision as more traditional assessments but with fewer questions and less time, or with greater precision. Early efforts had their drawbacks, of course, but we’ve come a long way in the intervening century or so. There is still much progress to be made, but some promising research today will likely change the way we assess students in the coming decade and beyond.
