At some point the mechanics of schooling begin running of their own accord. Such has become the case with grades (A's, B's, C's, etc.). This article reconsiders the history of grades through the concepts of immanence and abstract machines from the oeuvre of Deleuze and Guattari. In the first section, the history of grades as presently written until now is laid out. In the second, the concepts of immanence and abstract machines are described, and in the third section, problems are raised by reconsidering grades as machines (grade-machines).
