Seeing where students stand, early enough to act

A mark awarded at the end of a term is an accurate summary and a poor instrument. It arrives after the window for acting has closed, it aggregates across every concept taught, and it hides the one idea a student never secured underneath five they understood perfectly well. The information a teacher needs is the concept that broke, the students who share it, and enough time left to do something.

The writing in this category deals with both halves of that: the mechanics of how a missing prerequisite compounds into what looks like low ability, and the discipline of building analytics that answer a small number of questions attached to named owners and specific actions. A recurring theme is restraint. A flag should start a conversation, not attach a label, and a dashboard should be judged by the decisions it changes rather than by how much of the institution it depicts.

On the product side, student performance analytics covers the measurement layer, at-risk students covers the early-warning case, and schools and higher education show how the same evidence is used in two different institutions.
